Haematococcus Pluvialis Extract is derived from a freshwater microalga and is the primary natural source of astaxanthin, a potent carotenoid antioxidant used in skincare to help neutralize free radicals and reduce oxidative stress. It is incorporated for its purported protective and anti-aging benefits.
