Chromochloris zofingiensis is an emerging microalga with significant development potential, and its application prospects are rapidly gaining attention in the nutrition, health care, and cosmetics industries. Unlike Dunaliella salina,which is rich in β-carotene, Chromochloris zofingiensis demonstrates its core value through the efficient synthesis of astaxanthin and lutein.The astaxanthin it accumulates exists in a more stable esterified form, which is easily absorbed by the human body. With antioxidant capacity far exceeding that of vitamin C, this astaxanthin can effectively clear free radicals, delay cellular senescence, and exhibit excellent performance in relieving fatigue, protecting eyesight, and enhancing immunity. In the beauty industry, its potent antioxidant properties make it suitable for high-end oral beauty supplements and external skincare products, helping to combat photo-damage, reduce wrinkles, and enhance skin health and radiance from the inside out. It is a high-quality raw material driving innovation in natural bioactive ingredients.
