Astaxanthin, a powerful antioxidant mainly sourced from microalgae, such as Haematococcus Pluvialis, combats UV-induced skin damage by preventing thickening, collagen loss, and melanin formation. It belongs to the carotenoid group, known for colourful plant pigments like beta-carotene in carrots. Astaxanthin, available in supplements and skincare, has demonstrated its UV-protective prowess in studies. Research indicates improvements in wrinkles, age spots, elasticity, skin texture, and moisture content with its use. Additionally, it has shown wound-healing acceleration properties.
