In what form is green algae utilised?

Thegreen algae is also interesting for topical application. Creams, lotions, masks, scrubs... it is often found in skincare products. It can also be used in tinted cosmetic products, such as green concealers, due to its chlorophyll content. Because of its green colour, it is believed to be capable of "neutralising" the red colour and thus reducing the appearance of redness. Several studies have shown the effects of applying green algae on the skin.

The application of a cream containing C. vulgaris from 1 to 5% over a period of 7 to 28 days can enhance and accelerate the healing process. It may also improve skin hydration, possess antioxidant activity that counters the effects of skin ageing, and potentially reduce redness and vascular lesions, associated with conditions such as rosacea. It is important to note that this latter result is only a hypothesis.

The majority of studies have been conducted on cells, not on topical application to human skin. Therefore, the effects may not be as significant due to the penetration of the skin barrier.

Finally, you can apply thegreen algae to your hair, which is found in hair care products such as detangling milks and serums. To date, no study has proven any property of usinggreen algae on the hair. However, assumptions can be made about its possible hair benefits.

Indeed, we have previously mentioned potential antioxidant effects of green algae. It can also prevent lipid peroxidation. Hair fibre damage, linked to lipid oxidation, is part of the photo-aggravation of hair ageing. By absorbing and filtering incident light, hair pigments ensure the protection of hair proteins, such as keratin. However, when pigments act to protect these proteins, they themselves can be degraded, resulting in white hair. Green algae could reduce the effects of oxidative stress on the hair, making it less brittle, and may limit white or grey hair through the preservation of hair pigments.

These properties have not been scientifically demonstrated.
