What it is
Haematococcus pluvialis extract is obtained from a freshwater green microalga that accumulates high levels of the red carotenoid astaxanthin. In skincare it is used primarily for its antioxidant properties and lends formulas a characteristic reddish-orange tint. It is a popular ingredient in tone-up and antioxidant-positioned sunscreens.
Safety & warnings
This algae extract is generally well tolerated. Its strong natural color can occasionally lend a slight tint to a product or to very fair skin, which is cosmetic rather than a safety concern.
Origin & sourcing
Natural. It is derived from cultured Haematococcus pluvialis microalgae, often grown specifically to concentrate astaxanthin.
