All about algae: types, properties and benefits for the skin
Posted by Ivatherm
Seaweed is considered an important source of bioactive ingredients with cosmetic potential. Algae extract is used in skincare products due to its properties that contribute to maintaining a youthful complexion.
Algae are beneficial for hydrating, revitalizing, and soothing the skin, playing an important role in fading fine lines, wrinkles, and hyperpigmentation, as well as in treating conditions such as acne and cellulite.
Due to the antioxidant properties of seaweed, they protect the body from free radicals. Cosmetic products containing algae extracts contribute to improving skin elasticity and diminishing signs of aging by fighting against free radicals.
There are numerous types of algae, with experts estimating over 800,000 species. All types of algae are divided into two main categories: macro and micro. Macroalgae can be seen with the naked eye, while microalgae can only be seen with a microscope. However, both can be beneficial for maintaining skin health.

Algae: what they are, properties, and how to use them
Algae are photosynthetic organisms, similar to plants, that live in aquatic environments and have benefits for the body's health. Some types of algae have proven their effectiveness in maintaining skin health, offering a range of benefits such as hydration, exfoliation, and soothing irritated skin.
There are tens of thousands of species of marine algae, and they are divided into four major classes:
red algae;
brown algae;
blue-green algae;
green algae.
Algae extract can be found in numerous skincare products – from eye creams and moisturizers to serums and sun protection products.
Each type of algae has unique properties. Considered "wonder plants," algae can help unclog pores, increase skin hydration, prevent premature aging, and reduce fine lines and wrinkles. Some have anti-inflammatory properties, others are antioxidants, while others offer UV protection.
Algae contain a series of natural minerals with benefits for the skin:
magnesium – beneficial for soothing problematic skin;
potassium – helps detoxify the body;
sodium – keeps the skin hydrated;
calcium – supports elastin levels and collagen production.
Algae are also rich in carbohydrates, lipids, proteins, and amino acids. Algae extract is used both in cosmetic products for skin care and in some dietary supplements. Generally, cosmetics with algae extract can be used on all skin types.
What types of algae are used in skincare products?
Although all algae are rich in nutrients, vitamins (A, B, C, E) and minerals, each presents a series of unique benefits in skin care.
1. Brown algae
The most commonly used type of algae in cosmetic products, brown algae are rich in antioxidants and best support skin hydration and elasticity. Although brown algae extract is effective in many skincare products, it can be irritating for people suffering from acne.
2. Red algae
There are approximately 4,000 species of red algae, 98% of which are found in marine waters. A blend of polysaccharides, peptides, carotenoids, and fatty acids gives them antioxidant properties, which help smooth the appearance of fine lines and wrinkles and offer protection against the sun's harmful rays. Studies have shown that red algae can improve skin firmness. Due to their anti-inflammatory and hydrating properties, red algae are ideal for sensitive skin and dry skin. Also, red algae extract has a calming effect on the skin and can help reduce redness and irritation.
3. Blue-green algae
They are rich in antioxidants and contain vitamin B, amino acids, polyunsaturated fats, calcium, and proteins. They help maintain an optimal level of hydration. The best-known blue-green algae is spirulina. Rich in protein and essential amino acids, spirulina has anti-inflammatory and antioxidant properties, which help soothe irritated skin and protect it from damage caused by environmental factors. Additionally, spirulina can contribute to improving skin hydration levels, helping to maintain a bright and healthy complexion.
4. Green algae
Although not as frequently used in cosmetic products, green algae are rich in antioxidants and provide skin firmness. The best-known green algae is Chlorella. This is a type of single-celled algae, rich in vitamins, minerals, and antioxidants. It is known for its ability to detoxify the skin and offer protection against damage caused by free radicals. It also has moisturizing properties and can contribute to improving the skin's texture and overall appearance.
What are the benefits of algae extract for skin health?
Marine algae extract has been used to treat skin problems since ancient times. Currently, marine algae extracts are widely used in skincare products due to the large number of bioactive compounds. All four major classes of marine algae are used in skincare products: red algae, brown algae, blue-green algae, and green algae. Each class contains molecules with benefits for the skin, such as: Omega-3 fatty acids, amino acids, and vitamins A, B, C, and E.
Due to its antioxidant properties, which help efficiently neutralize free radicals and reduce oxidative stress, algae extract can work to strengthen the skin's barrier function and soothe it.
At the same time, studies have shown that the topical application of algae extract contributes to skin brightening and the fading of aging signs.
The properties of algae extract make it an ingredient that promotes skin health, which is why it is included in numerous skincare products.
Some of the benefits that algae extract has on the skin are the following:
1. Protects the skin from free radicals
Algae have antioxidant properties that help counteract the effects of free radicals. At the same time, some types of algae, especially red algae, also have antifungal and antibacterial activity, protecting the body from germs.
Algae extract has numerous beneficial compounds, such as polysaccharides, proteins, lipids, pigments, and vitamins, which are easily absorbed by the skin. Certain bioactives, such as carrageenan, make it possible to protect the skin against environmental stressors.
2. Offers protection against ultraviolet rays
Algae act as antioxidants, contributing to the absorption of solar energy and protecting the body from ultraviolet rays. Red and brown algae are recommended for combating oxidative stress, especially that induced by exposure to UV radiation.
In addition, algae produce water-soluble molecules called amino acids, which act as additional UV protection. As a result, algae extract can be effective in products with sun protection factor.
Prolonged sun exposure is one of the main causes of premature aging. Using cosmetic products with algae extract, along with an SPF cream, contributes to maintaining a youthful appearance of the skin for as long as possible.
Rosederm Cream for sensitive couperose skin SPF30 – contains Aldavine 5X™ (a polysaccharide complex of brown and red algae), Dextran Sulfate, Alpha-Bisabolol, Herculane thermal water, and sun filters.
3. Fades the appearance of fine lines and wrinkles
Natural antioxidants inhibit enzymes that break down collagen fibers (the main structural protein of the skin, which provides strength and elasticity) and thus delay the appearance of the first signs of aging. By introducing algae extract into the skincare routine, the skin is helped to naturally maintain its optimal collagen level.
Antioxidants also play an important role in protecting the skin from the harmful effects of free radicals. Because they block and counteract the effects of free radicals (which the body produces in reaction to pollutants and UV radiation), antioxidants protect skin cells from oxidative damage, thus preventing premature skin aging.
Some algae can protect the skin's natural hyaluronic acid reserves, thereby improving hydration levels.
Glykolift Anti-wrinkle lifting cream – contains brown algae extract, Glycokine Factor S™, hyaluronic acid, Shea butter, vitamin E, and Herculane thermal water.
Glykolift Lifting serum – contains brown algae extract, Glycokine Factor S™, hyaluronic acid, vitamin E, and Herculane thermal water.
Aquafil Hydra Complex Eye contour gel cream – contains Aldavine 5x™ (a polysaccharide complex of brown and red algae), Aquaphyline, Matrixyl ®3000, hyaluronic acid, glycerin, and Herculane thermal water.
4. Contributes to skin rejuvenation
Algae extract contains antioxidants, vitamin B, magnesium, zinc, and other vitamins and minerals that support skin detoxification by eliminating impurities and unclogging pores.
For deep detoxification, Chlorella is an optimal choice. Being rich in vitamin B, magnesium, and zinc, this green algae helps detoxify the skin without drying it out.
5. Prevents skin eruptions and fades acne marks
In addition to antioxidants, algae extract has strong antimicrobial properties, which slow down bacterial multiplication. Thus, the skin remains clean, without imperfections and skin eruptions.
Red algae are frequently used in treating comedones (blackheads and whiteheads) and cysts. Algae extract contains high levels of beta-carotene, a precursor of vitamin A, which is a recognized ingredient in acne treatment, through its derivatives: retinol, Granactive Retinoid, etc.
6. Contributes to skin brightening and fading hyperpigmentation spots
Algae work as a natural brightener. They have skin-brightening properties that can help diminish the appearance of pigmentation spots.
Red, brown, and green algae contain significant levels of vitamin C, an essential ingredient for revitalizing the complexion. This antioxidant is ideal not only for protecting the skin from free radicals but also for brightening and balancing uneven skin texture.
Marine algae can also be used as a natural exfoliant, removing dead skin cells so that the skin regains its radiance.
Cosmetic products containing algae extract can help even out skin tone and eliminate dark spots.
7. Helps lock in moisture for deep hydration
When used in skincare products, algae help lock moisture into the skin, so it is always well-hydrated. Some research suggests that brown algae provide greater water retention than hyaluronic acid.
When skin is dry, your complexion looks dull, and the risk of fine lines and wrinkles appearing is higher.
People with dull and dry skin can opt for skincare products containing algae extract, considered a good humectant.
Conclusion
In conclusion, algae extract offers numerous benefits: from protection against harmful environmental factors to hydrating and soothing irritated skin. Thus, products containing algae extract are a good choice for improving skin appearance and maintaining skin health.
