Good

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Dried microalgae (the source of astaxanthin) — a powerful natural antioxidant with good food-use safety data.

Haematococcus pluvialis powder is the dried biomass of the freshwater microalga Haematococcus pluvialis, a rich natural source of astaxanthin — a carotenoid with exceptionally high antioxidant capacity. The algae and its extracts are approved as a food supplement ingredient in the EU (Novel Food) and US (GRAS) with extensive oral safety data. In cosmetics it provides antioxidant protection, photoprotection support, and skin-conditioning via its carotenoid payload. No GHS hazards or IARC classifications. Main formulation challenges are its deep red-orange color and oxidative sensitivity.
