Cosmetics
Algae represents a versatile and expanding platform for cosmetic and personal care applications, driven by its rich profile of bioactive compounds. Diverse algal species produce pigments, antioxidants, polysaccharides, and lipids that support a wide range of skin and haircare functions.
Current capabilities include the development of algal-derived ingredients for hydration, skin barrier support, and antioxidant protection, as well as compounds that help manage pigmentation and maintain skin clarity. Naturally occurring UV-absorbing molecules and carotenoid pigments further position algae as a promising source of protective and restorative actives.
In haircare, algal extracts are being explored for their functional properties in scalp health, moisture retention, and fibre nourishment, alongside emerging applications targeting dandruff and ageing-related changes. Ongoing research is focused on optimising extraction processes, improving bioactivity, and ensuring formulation compatibility to enable scalable integration into commercial products.
Key algal-derived extracts and compounds include:
- Polysaccharides– hydration, film-forming, skin barrier support
- Carotenoids (e.g. β-carotene, astaxanthin, fucoxanthin) – antioxidant protection, skin tone support
- Polyphenols – anti-inflammatory and antioxidant functions
- Mycosporine-like amino acids (MAAs) – natural UV absorption and photoprotection
- Chlorophyll – cleansing and antioxidant properties
- Lipids and fatty acids – emollient and skin-conditioning benefits
- Proteins and amino acids – skin repair and hair strengthening
With increasing demand for sustainable, bio-based ingredients, algae-based platforms offer a renewable and adaptable solution for next-generation cosmetic innovation.
