Algae are highly valued in the cosmetics industry for their richness in nutrients and vitamins. Proteins, minerals, antioxidants and omega-3 fatty acids, which promote hydration and elasticity, can improve the skin and protect it from free radical damage.
Algae – Cosmetic All-Rounder.

Brown algae, green algae and red algae are commonly used in cosmetic products. Brown algae are rich in iodine, potassium, zinc and other minerals and are often used in moisturizers as well as lotions. Green algae are a good source of antioxidants. They can help brighten the complexion and reduce dark spots. Red algae, on the other hand, are often used in products to treat cellulite, as they can improve the appearance of what is known as “orange peel skin.”

It is important to note that not all algae are suitable for use in cosmetic products. It is also important to note the differences in the effectiveness of different types of algae. So which algae are suitable for any cosmetic areas? This question will be answered in the following blog, accompanied by some recommendations and product ideas based on algae.

Anti-Aging / Wrinkles

Lasting helpers for young skin.

Algae can be an effective ingredient in anti-aging and anti-wrinkle cosmetics. The variety of nutrients, antioxidants and other compounds that algae contain can help improve the health and appearance of the skin.

For example, some algae, such as the red microalgae Porphyridium purpureum, contain high levels of vitamins A and C, which have been shown to stimulate collagen production and improve skin elasticity. Other types of algae, such as Fucus vesiculosus, are rich in omega-3 fatty acids, which can help hydrate the skin and improve its overall texture.

Strong antioxidant properties come into play through compounds such as fucoxanthin and phlorotannins. This protects the skin from environmental stresses that can lead to premature aging. As with any skin care product, it is important to choose one that is suitable for your skin type.

Algae – cosmetic all-rounders – offer an ideal symbiosis between active and sustainable ingredients for the anti-aging products and cosmetics of the future. With their aesthetic effect, they not only promote the health process of the skin, but also prevent the aging process.

Skin Protection / Antioxidant

Protect the skin from external influences?

Algae are true helpers for the skin. They not only provide abundant nutrients, but also protect the skin from external influences and oxidative stress. Oxidative stress can damage the skin, which can be prevented by radical scavengers – antioxidants.

Algae are a rich source of antioxidants and have been used in various skin care products for centuries due to their numerous benefits to the skin. Antioxidants protect the skin from oxidative stress caused by free radicals, which can lead to premature aging and other skin problems. The astaxanthin content in some algae, such as the microalgae Haematoccocus pulvialis, is the richest form of antioxidants and is usually recommended or already used and applied in the form of oil.

Antioxidants are also known to hydrate the skin, improve its texture and overall appearance, soothe and relax irritated skin. Algae species, such as Asparagopsis armata, with antioxidant content have unique properties and benefits for the skin.

Protect from the sun with algae?

Even the smallest ray of sunlight increases the risk of skin cancer and can accelerate the aging process of the skin.

Algae can provide additional protection from the sun and also provide ample moisture for skin that stays young. They can be photoprotective through their ingredients, including fucoidan and MAAs (“mycosporins like amino acids”). One example of this is the brown alga Undaria pinnatifida (Wakame), which plays a major role not only in the food sector but also in the cosmetics industry. Algae – cosmetic all-rounder.

Algae can be used in sunscreens as a complementary natural source of UV-absorbing compounds such as mycosporine-like amino acids (MAAs). MAAs can help protect the skin from harmful UV radiation by absorbing the energy and dissipating it in the form of heat. This reduces damage to DNA and other cellular structures.

Natural organic substances contained in the formulation of mineral sunscreens complement these and other protective factors, and at the same time the natural substances from the algae protect the environment.

Nourishment / Remineralisation

The supply of essential health resources.

Algae not only provide a rich supply of nutrient-rich minerals, but can also improve cell metabolism and promote blood circulation in the skin – pure skin appearance. The antibacterial and cleansing effects brought to bear by the algae Laminaria digitata, for example, are optimal for sensitive and easily irritated skin.

As an ingredient in peelings & oils, the natural skin barrier and connective tissue are strengthened. Algae – cosmetic all-rounders – such as the green alga Chlorella vulgaris, can be used for nutrition and remineralization due to their high nutrient content, especially of minerals such as calcium, magnesium and iodine.

How can algae promote the recovery process and also provide anti-aging properties?

Schizochytrium sp. and some other algae can protect cells from oxidative stress, which inhibits inflammation, reduces cell damage and can contribute to a healthy skin appearance.

Algae may have anti-inflammatory properties due to their high content of bioactive compounds, such as polyunsaturated fatty acids (PUFAs), phycobili proteins and polysaccharides. These compounds have been shown to inhibit the production of pro-inflammatory cytokines and enzymes that may contribute to the development of chronic inflammation and related diseases.

Some studies have demonstrated the anti-inflammatory effects of algae extracts or whole algae in vitro and in vivo, suggesting their potential as a natural anti-inflammatory agent for human health. Algae – cosmetic all-rounders – such as Haematococcus pluvialis, Schizochytrium sp. and Cystoseira humilis, are rich in bioactive substances and are mostly recommended in liquid oil form for processing in cosmetics.

Fighting harmful bacteria of the skin flora with algae?

Whether Propionibacterium acnes, Staphylococcus aureus, Bacillus subtilis, Escherichia coli can be limited with the potential of red algae Pterocladiella capillacea and some other algae. They soothe the skin and hair by fighting harmful bacteria. The antibacterial substances can exert an inhibitory effect on the entire bacterial culture.

Through their bioactive compounds, such as polyunsaturated fatty acids (PUFAs), phlorotannins and polysaccharides, they have been shown to have an antibacterial effect against various strains of bacteria. These compounds can destroy the bacterial cell membrane or inhibit the activity of enzymes important for bacterial survival. Some studies have tested the antibacterial effect of algae extracts or whole algae in cosmetic formulations, suggesting their potential as a natural antibacterial agent for body – care products.
