Aloe Vera

The Aloe Vera plant has been known and used for centuries for its health, beauty, medicinal and skin care properties.

The name Aloe Vera derives from the Arabic word “Alloeh”, meaning “shining bitter substance”, while “Vera” in Latin means “true”.

2000 years ago, Greek scientists regarded Aloe Vera as the panacea.

The Egyptians called Aloe “the plant of immortality.”

Today, the Aloe Vera plant is been used for various purposes in dermatology and cosmetic products.

The history of aloe Vera is steeped in anecdotes and mysticism.

The earliest description of it is to be found in an Egyptian papyrus dating from 1,500 years BC.

It comes as no surprise that Nefertiti and Cleopatra, the most beautiful queens of Egypt, considered it a ‘wonder plant’ using it both as a cosmetic and a protective amulet.

It is also known that the Greeks, through the writings of Hippocrates and Theophrastus, studied the aloe as a medicinal plant and that Theophrastus even suggested to Aristotle a large-scale harvest of it to relieve the wounds suffered by the soldiers led by his pupil, Alexander the Great.

The Arabs of Al-Ándalus, who were great admirers of the plant’s therapeutic properties, left large crop crops at the end of the Christian Reconquest. Likewise, through their religious missions, the Spanish Jesuits introduced the aloe into the newly-discovered continent of America, mainly through the West Indies.

In Renaissance Europe, its pharmaceutical application was overshadowed by its use as an ornamental pot plant. It became relegated as a fall-back remedy to a laxative or as an antiseptic for public places in times of plague.

More recently, there are records of it being used as a cell regenerator with the first patients exposed to X-rays and with the victims of the bombings of Hiroshima and Nagasaki at the end of the Second World War.

In 1970, scientists succeeded for the first time isolating the aloin—the essential molecule of the aloe—thereby initiating the proliferation of formulas for cosmetic products and mass production.

Because Aloe Vera comes from hot and desert places, its cultivation requires that the minimum temperatures do not drop below 0 °C.

Intense frosts or weak frosts, but repeated cause damage, as it is not cold tolerant; neither does it tolerate humidity, neither in the soil nor on the plant. It can be located in full sun or in semi-shade.

Aloe Vera is grown on a large scale in Australia, Bangladesh, Cuba, the Dominican Republic, China, Mexico, India, Jamaica, Colombia, Venezuela, Kenya, Peru, Tanzania, and South Africa, along with the United States to supply the cosmetic industry.

In Spain its cultivation is more and more common, being Córdoba the main producing area, finding in the Canary Islands a totally wild and ecological crop.

The plant has triangular, fleshy leaves with serrated edges, yellow tubular flowers and fruits that contain numerous seeds.

Each leaf is composed of three layers:

1) a clear inner gel that contains 99% water and the rest is made of glucomannans, amino acids, lipids, sterols and vitamins.

2) The middle layer of latex is the bitter yellow sap and contains anthraquinones and glycosides.

3) The thick outer layer of 15–20 cells called rind has a protective function and synthesizes carbohydrates and proteins.

Inside the rind are vascular bundles responsible for the transportation of substances such as water (xylem) and starch (phloem).

Aloe Vera contains 75 potentially active constituents: vitamins, enzymes, minerals, sugars, lignin, saponins, salicylic acids and amino acids.

  1. Vitamins: It contains vitamins A (beta-carotene), C and E, which are antioxidants. It also contains vitamin B12, folic acid, and choline. Antioxidant neutralizes free radicals.
  2. Enzymes: It contains 8 enzymes: aliiase, alkaline phosphatase, amylase, bradykinesia, carboxypeptidase, catalase, cellulase, lipase, and peroxidase. Bradykinase helps to reduce excessive inflammation when applied to the skin topically, while others help in the breakdown of sugars and fats.
  3. Minerals: It provides calcium, chromium, copper, selenium, magnesium, manganese, potassium, sodium and zinc. They are essential for the proper functioning of various enzyme systems in different metabolic pathways and few are antioxidants.
  4. Sugars: It provides monosaccharides (glucose and fructose) and polysaccharides: (glucomannans/polymannose). These are derived from the mucilage layer of the plant and are known as mucopolysaccharides. 
  5. Anthraquinones: It provides 12 anthraquinones, which are phenolic compounds traditionally known as laxatives. Aloin and emodin act as analgesics, antibacterials and antivirals.
  6. Fatty acids: It provides 4 plant steroids; cholesterol, campesterol, β-sitosterol and lupeol. All these have anti-inflammatory action and lupeol also possesses antiseptic and analgesic properties.
  7. Hormones: Auxins and gibberellins that help in wound healing and have anti-inflammatory action.
  8. Others: It provides 20 of the 22 human required amino acids and 7 of the 8 essential amino acids. It also contains salicylic acid that possesses anti-inflammatory and antibacterial properties.
  9. Lignin, an inert substance, when included in topical preparations, enhances the penetrative effect of the other ingredients into the skin.
  10. Saponins are soapy substances that form about 3% of the gel and have cleansing and antiseptic properties.

Topical: May cause redness, burning, stinging and rarely generalized dermatitis in sensitive individuals. Allergic reactions are mainly due to anthraquinones, such as aloin and barbaloin. It is best to apply it to a small area first to detect a possible allergic reaction.
Oral: Abdominal cramps, diarrhoea, red urine, hepatitis, dependency or worsening of constipation. Long-term use has been reported to increase the risk of colorectal cancer. The laxative effect can cause electrolyte imbalances (low potassium levels).
Contraindication: Contraindicated in cases of known allergy to plants of the Liliacea family (people allergic to garlic, onions or tulips are more likely to be allergic to Aloe Vera).
Pregnancy and breast-feeding: Oral aloe is not recommended during pregnancy due to the theoretical stimulation of uterine contractions and, in breastfeeding mothers, it can sometimes cause gastrointestinal upset in the infant.
Interactions: Applying aloe to the skin can increase the absorption of steroid creams such as hydrocortisone. It reduces the effectiveness and may increase the adverse effects of dioxin and digitoxin, due to their potassium-lowering effect.

The combined use of Aloe Vera and furosemide can increase the risk of potassium depletion. It lowers blood sugar levels and therefore can interact with oral hypoglycaemic agents and insulin.


  • If you take medications regularly, talk to your doctor before using aloe supplements as they can interact with them.
  • Do not apply Aloe Vera to deep cuts or severe burns without the supervision of a healthcare professional.
  • Aloe Vera supplements should not be used by young children or pregnant or breastfeeding women.
  • Long-term use can lead to the loss of electrolytes, especially potassium. One of the ways we can tell if we tolerate oral Aloe Vera well is simply by checking our body’s immediate reactions. If you experience any side effects after using it for a short period of time (1-2 weeks), stop and wait at least a month before starting again.

Scientific researchers have never reached a consensus over the origins of the aloe barbadensis miller. Its origins have been attributed to every corner of the world, from the tropics of Jamaica, Barbados or Guyana to the deserts of the Arabian peninsula or tropical Africa. Many experts have also found in the Socotra archipelago’s endemism (of which the Canary Islands are a part) the ideal conditions whereby this plant could have seen life for the first time, thousands of years ago.

What is certain is that nowadays, the Canary Islands can claim with pride that they are the leading region of Europe in Aloe Vera’s production.

Aloe Vera is mainly grown in the most northern part of the archipelago—Lanzarote, Fuerteventura and Gran Canaria—where it benefits from the soil’s characteristics: cool and deep, with a particular acid level, and free from the risk of waterlogging.

On Lanzarote alone, almost 150 hectares of land are dedicated to the cultivation of aloe, with production reaching 6 million kilos per year.


By natural cosmetics, we understand a product made from natural ingredients or has a biological origin.
When most of the vegetable ingredients of a natural cosmetic are ecological farming, we speak of environmental cosmetics, also called biological or organic.
The skin is the largest organ in our body and the most exposed to the outside world.
It is the first line of defence against microorganisms. For this and many reasons, it needs the best of our care.
Also known as organic cosmetics, these products are very favourable for the skin since being made only with natural ingredients. They are very respectful of the skin and do not cause allergies or redness.
  • Organic, biological ingredients and bioproducts from organic farming
  • Does not contain parabens, paraffin or other petroleum derivatives
  • They do not contain silicones
  • Does not use synthetic chemical ingredients or genetically modified organisms
  • Animal testing is not performed
  • Only use fragrances with natural ingredients
  • The packaging is made from recycled and environmentally friendly products.
  • Ecological product is known in Spain mainly
  • The biological product is used in Germany, France
  • An organic product is usually used more in the United States, United Kingdom
A cosmetic can be considered “BIO” when the formula is composed of 95% ingredients of vegetable origin and of all those ingredients by weight a minimum of 10% must come from organic farming.
Some very frequent ingredients in cosmetics (water, salts, minerals) cannot be certified as organic, since they are not obtained from agriculture.
For example, in some shampoos and creams, water is the majority compound, so they contain between 10% and 40% organic ingredients, and always 95% natural ingredients.
An essential oil, which does not contain water, can be 100% organic ingredients.
The lack of specific regulations for the production of organic cosmetics (unlike the existing legislation for the production and cultivation of organic food products) makes it challenging to define the parameters that these products must follow.
Without a legal entity that protects and guarantees the standards defended by organic cosmetics, independent certifications are the only way to ensure the product’s integrity and authenticity to the final consumer.
In the absence of certification, the bio or truly natural cosmetic quality and integrity depend exclusively on the laboratories’ competence and honesty that develop them. That’s why we defend certification.
It is the safest way to guarantee high-quality ingredients and the use of chemical-free products that are harmful to health. A cosmetic product is declared natural does not mean that its constituents are not contaminated, nor does it prevent the addition of chemicals used as solvents, preservatives or antioxidants in its manufacturing process; natural means that it contains natural extracts.
The certification logo of a product allows the consumer to identify whether it is an organic or truly natural cosmetic without thoroughly analysing the ingredients.

All products are manufactured using natural, ecological and BIO certificates.

  • A.C.E.N.E. NAT
  • A.C.E.N.E. BIO
  • A.C.E.N.E. VEGAN
  • EcoCert
  • Bio.inspecta
  • BioVidaSana

In natural cosmetics, the most widely used preservatives are organic acids and their salts: Benzoic acid and its salts (Sodium benzoate), Sorbic acid and its salts (Potassium sorbate). They are active at pH below 5.0.

GeodermAloe products are aimed at youth and adults. Our products are topical and as naturally as possible, although they are for any skin conditions, the ingredients are not directed to children under 3 years. Children have a different pH of the skin, and it is better to consult a doctor before applying any GeodermAloe product.

All brands can cause an allergic reaction to any of their products or components. In the case of bio brands, these reactions tend to be minor and much less likely, but they can exist.

95% of allergic reactions are due to the use of chemical products or synthesis in cosmetics.
Even so, a person can be allergic to any ingredient, such as orange or strawberry, and react to it, even if they are of quality, as is the case with food allergies.

If you are allergic to a product contact us directly. It is important to know what products you are using, and try one product at a time, and look for the most active ingredients that can cause a reaction.

Despite the properties of Aloe Vera, its intake during pregnancy is not highly recommended, since due to the detoxifying and purifying effect, it can produce uterine contractions with the risk of abortion or premature birth.
Something similar can happen during breastfeeding. Breast milk is formed with everything the mother eats, so it is advisable that the mother not drink it, as it can interfere with the state of the milk.
To avoid this problem, pregnant women can use Aloe Vera gels with complete peace of mind. Usually, a good product is free of the aloin that sits between the gel and the fibrous part of the leaf and sees the use of only the stabilized inner gel.
Therefore, the consumption of aloe Vera within a diet for pregnant women is not recommended.
It is recommended topical use to combat stretch marks, acne, scars, tired legs and helps hydrate dry skin.
The use of aloe Vera during pregnancy helps pregnant women to combat excessive tiredness, heavy legs, fatigue and problems with digestion, especially during the last months of pregnancy.

If stored in a vacuum package, it can last a lifetime when exposed to air depends on the storage conditions.

Well-kept in a cool, dry place without direct sunlight can last for six months to a year.

It is also essential to always apply our products with washed hands, thus avoiding product contamination.

All certified biological products are forbidden to carry out animal tests on the final product, as well as animal tests on the raw materials that compose them, so all GeodermAloe products are cruelty-free.

Not all GeodermAloe products are vegan, as they may contain ingredients such as honey or beeswax. Even so, all of our products are cruelty-free and many are also vegan, and we are working on improving the quality and making all of our products vegan.

No. Organic cosmetics may contain wheat or barley derivatives that may contain gluten. But we have many gluten-free alternatives.

Skin Conditions

Psoriasis is a disease that causes dehydrated skin and can cause peeling and form a wound or scab. Usually emotional in origin, it arises from outbreaks related to more stressful episodes in daily life.

For the face, you can use soaps, multivitamin serums and Aloe Vera pure gel.

For the body, we recommended our shower gel and, followed by hydration with argan oil or body oil, an excellent option to use immediately after bathing. They must be complemented for long-lasting hydration.

We have a shampoo with Aloe Vera, Biotin, Panthenol, Collagen and Honey Extract for the scalp. In addition to a hair conditioner, they are also reasonable solutions to calm and regenerate your scalp skin.

You can also use body milk with passion fruit for the body, which is good for sensitive and dehydrated skin.

All our options are indicated, because our cosmetics are free of synthetic chemicals and are suitable for sensitive skin and any skin conditions, compromised immunity, among others.

However, always ask for medical advice for your particular case.

The best treatment for scars and stretch marks is to regularly nourish and massage the area with rosehip oil, argan oil or oil mixtures that contain at least one of them. The redder the mark or scar, the faster you will see results.
We have the Aloe Vera and Rosehip dermal gel that has a high rosehip content and is especially recommended to hydrating and regenerate the skin. A highly recommended product for dry skin, skin blemishes, stretch marks, scars, body care.
Herpes is a virus, latent in the body, which becomes visible when the immune system is low, usually in situations of emotional stress, fatigue, seasonal changes and ingestion of some foods (spicy, alcohol, oranges and general acidic fruits, etc.)
The drier the skin, the more likely it is for herpes to break out. Thus, correct hydration of the affected area can be carried out, so that, in the event of an eruption, it is less violent.
In case of a rash, we recommend the use of lip balm with Aloe Vera, a moisturizer, nourishing and soothing, especially suitable for dry and damaged lips and together with pure aloe Vera gel, which can be applied at night.
The skin of the neck and cleavage is much more delicate than the face skin. It is also more prone to the appearance of wrinkles. Even so, the rules are the same as those applied to the face, being necessary to nourish the skin with ingredients that allow it to defend itself when necessary (from pollution, the sun, loss of hydration, etc.).
However, there are some valuable tricks to protect these areas.
For example, avoid using very hot water in the bathroom and dry your neck without rubbing it, try once a week to do a gentle exfoliation in the area (you can use the facial or body scrub (scrub with volcanic sand or scrub with apricot seeds), but do not apply too much pressure, you can even mix it with a little cleansing milk) and then apply the anti-ageing facial serum with SPF 50, keep the posture straight, shoulders back and head upright and always use a specific moisturizer for this area or your facial moisturizer.
Some products to use in the neckline and cleavage area:
  • The SPF 30 sunscreen cream, in addition to protection against UVA and UVB rays, prevents your skin from pigmenting, gaining more wrinkles and drying out.
  • Pure Argan oil, the exceptional richness of this oil in essential fatty acids and vitamin E offers the best protection of the skin against aggressions, has strong regenerative power, being very effective in the prevention and reduction of the signs of ageing (wrinkles and pigmentation spots).
  • Aloe Vera Anti-ageing Serum with Protector SPF 50+ is an oil-free serum, for all skin types, and protects against photoaging.
  • Anti-ageing facial cream with impressive active ingredients that helps reduce the appearance of wrinkles. Aloe Vera contains emollient, softening, anti-inflammatory and regenerating properties. Collagen acts as a natural filler for wrinkles and expression lines. Retinol stimulates the natural production of collagen, reduces pores and clears spots. The Barbary fig oil provides flexibility, elasticity and luminosity to the skin. Ginger extract has antioxidant properties on facial skin.

Sun Protection

Sunscreen creams, oils or lotions have had a long development until now. In Ancient Greece, the Greeks used olive oil as a type of sunscreen, but its effectiveness was reduced. Various researchers have tried for centuries to create a sunscreen, but we had to wait until 1944.
Pharmacist Benjamin Greene tried to create something to protect soldiers in WWII from the severe sunburns they suffered.
In the oven in his house, he created a red, slimy substance that worked by physically blocking the sun’s rays. This substance was a derivative of petroleum, similar to petroleum jelly, which was called “red veterinary pet”: red veterinary petroleum jelly.
Since this first experience, sunscreens have undergone a great evolution, although many continue to be based on petroleum products.
Chemical sunscreens act by neutralising the sun’s rays: they are placed on the skin, and when in contact with the sun’s rays, neutralize them before they can be harmful to the skin.
They have the problem that when the rays degrade them, they generate free radicals and when the skin absorbs them, they contribute to the increase in skin cancer.
You must apply the sunscreen 30 minutes before sun exposure and, as the substances react with the sun, they degrade and penetrate the body.
These substances, the result of the degradation of sun protection, are being studied because they increase skin cancer prevalence. However, these types of sunscreens are easier to spread and do not leave colour on the skin.
Some studies indicate that the performance of these chemical agents affects similar to female pheromones. In the long term, they lead to endocrine disorders harmful to our health.
In addition to these dangers, chemical sunscreens pose a threat to coral reefs and the entire marine ecosystem.
Our sunscreen creams are high in Aloe Vera and make a beautiful tan and preserve your skin’s health.
Its fluid and scented texture offer an ultra-easy and ultra-fast application for homogeneous water-resistant protection. Rich in Aloe Vera, whose regenerating and moisturizing virtues are used to complete the properties of the cream.

SPF is the acronym in English for Sun Protection Factor; It is an indicator of the ability of a protector to protecting us from sunburn.

The SPF thus indicates the relationship between the time of sun exposure and the percentage of protection provided by the sunscreen.

The SPF (Sun Protection Factor) is a laboratory measurement that indicates the effectiveness of sunscreen: the higher the SPF value, the greater the protection offered by the sunscreen against UVB rays (the ultraviolet radiation that causes sunburn).

The SPF indicates the relationship between the time that the person can be exposed to sunlight before burning with and without sunscreen.

For example, a person who would burn after 12 minutes in the sun without protection, protected with a sunscreen SPF 10 (10 times more protection) should now take 2 hours (120 minutes) to reach the same degree of burn.

In terms of effectiveness, it is important to understand the different performance percentages for each factor. SPF15 sun protection blocks 93% of UVB rays, while SPF 30 protection blocks 97% and SPF 50 protection blocks 98%.

Ultraviolet (UV) rays have different wavelengths and penetrate deep into the skin, into the dermis. Taking into account the damage caused by UVA radiation, it is recommended to check the existence of UVA filters in the products.
However, as there is not yet a standard method for evaluating UVA radiation filters in sunscreens, but when these products have the filters this is indicated on the product packaging.
UVB rays, more present in summer, reach a shorter length, penetrating the epidermis of the skin.
The formation of free radicals (RF), indirectly alters DNA, which can lead to ageing or skin cancer.
In the case of the indicated products, as long as they reflect part of the UVB spectrum, a product may contain the acronym SPF and, therefore, be considered a sunscreen. However, it does not mean that it protects us from UV radiation.
  • Avoid sun exposure between 12 pm and 4 pm.
  • Wear clothes, hats and sunglasses to protect ourselves more from solar radiation. Choose light white clothing and hats that protect from UVA and UVB rays.
  • Put on sunscreen as complementary protection and reapply frequently (maximum every 2 hours) to maintain protection or whenever we sweat or swim.
  • Being in the shade is also a form of protection, but be careful with reflected light. Sunlight reflects off the sand and reaches the skin, even in the shade. That is why the other protection measures must be maintained.
  • Do not expose very young children to direct sunlight. Maintain the same level of protection on cloudy days, as 40 to 60% of radiation passes through clouds.

This is unlikely to happen because by blocking solar radiation, we also prevent vitamin D synthesis.

The sun has an essential function in the body – the production of vitamin D – it is undoubtedly our greatest source of this vitamin!

Sunscreens prevent the rays from being absorbed by the skin and inhibit the body from synthesizing vitamin D.

In general, 10 to 15 minutes of sun exposure, every other day, without sunscreen and at the right times, is enough for most people to synthesize vitamin D.

This exposure does not need to be full-body. Only the arms, hands or face is sufficient.

Therefore, the ideal is an intermediate, between protection for longer exposures and in the most dangerous hours and walking without protection in the hours of less danger and for shorter periods.
