Actibiom

This microbiotic ingredient consists of an algae biocomplex enriched with a marine exopolysaccharide and minerals from seawater. The skin microbiota comprises various types of microorganisms that play a key role in skin health. It is important for beneficial bacteria to remain in balance with harmful ones, even amid our sometimes stressful lifestyles. The formula is designed to mimic a healthy, balanced diet for the skin. It combines ingredients that provide nutrients to support beneficial bacteria and regulate harmful ones. Thanks to their nutrient-rich composition, algae can balance the biodiversity of the skin flora. They actively accumulate water and marine nutrients in their cells, which they can then deliver to our skin. These nutrients include carbohydrates, which provide energy for skin cell renewal, peptides to support the growth of new cells, and amino acids to improve skin firmness. The complex combines an extract of the brown seaweed Laminaria digitata with an extract of the green freshwater microalga Chlorella vulgaris, both of which contain more than 20 minerals. Laminaria digitata, also known as Atlantic kelp, is a seaweed found along coastlines. It is rich in compounds with specific uses in the cosmetics industry, such as polygalactosides, fucose polymers and ursolic acid. Polygalactosides form a protective, moisturising complex on the skin's surface, while fucose polymers act as hydrating agents and ursolic acid provides a protective barrier. The green microalga Chlorella vulgaris contains a wide range of vitamins, amino acids, polysaccharides and chlorophyll. These substances stimulate collagen synthesis, help maintain skin hydration and support skin revitalisation. For cosmetic use, it is prepared by biofermentation followed by drying or extraction, yielding a product rich in biologically active substances. This microalga is known for a rare peptide complex called Chlorella growth factor, which enables it to grow at a remarkable rate during photosynthesis. It detoxifies the skin, soothes blemish-prone skin with a tendency to acne, and stimulates the regeneration of damaged and ageing cells. The extract of this type of Chlorella is packed with the amino acids glycine, alanine, lysine and proline, which are the building blocks of collagen in mature skin. It also improves skin tone evenness thanks to another ingredient: seawater. Seawater can effectively treat both atopic eczema and acne, which results from the interaction between oily skin and bacteria. Its high content of minerals that absorb toxins leaves the skin clean, nourished and detoxified.

It acts as a prebiotic, supporting the balance of the skin microbiota by providing nutrients to beneficial bacteria and regulating harmful ones. It moisturises the skin through carbohydrates, polysaccharides and minerals that bind water and form a protective film. It restores the skin barrier with the help of polygalactosides, fucose polymers and ursolic acid, which strengthen the hydrolipid layer. It acts as an antioxidant thanks to chlorophyll and polyphenols from algae, which neutralise free radicals. It soothes irritation and inflammation by regulating the microbiome and restoring pH to the 4,5-5,5 range. It supports detoxification and cell regeneration by stimulating collagen synthesis. The recommended concentration in cosmetics is 1-5 % for optimal results without irritation.

Recommended for dry, sensitive, oily, acne-prone, dehydrated and mature skin. Ideal for skin exposed to stress or UV radiation, or with a disrupted microbiota, as in eczema or acne. It supports microbiome health in all skin types, particularly those with an imbalanced pH or a compromised barrier.

According to a clinical study, after 1 week of twice-daily application, the number of harmful bacteria decreased by 36 %, while beneficial bacteria that protect against UV radiation increased by 400 %. Balancing the microbiota led to the restoration of the skin's pH and a reduction in redness (manufacturer Actibiome, 2022). Another study confirmed that beneficial bacteria such as Staphylococcus epidermidis produce the enzyme urocanase, which breaks down cis-urocanic acid formed under UVB radiation, thereby protecting the skin from damage (Journal of Investigative Dermatology, 2020).
