Some skincare ingredients are nice-to-have. Others are game-changers. Astaxanthin firmly belongs in the latter category. Naturally derived from microalgae, this potent carotenoid is one of the most powerful antioxidants in the skincare world—boasting up to 6,000 times the antioxidant strength of Vitamin C. At Cellis, we’ve made it a hero in both our Everyday C Complex and Overnight A Complex, because its skin benefits are too compelling to ignore.

At Cellis, every ingredient earns its place. Liposomal Retinol isn’t a trendy inclusion—it’s a smart upgrade grounded in skin science. Traditional retinol is celebrated for its ability to accelerate cell turnover, reduce fine lines, and smooth skin texture. But it comes with baggage: irritation, sensitivity, and a steep acclimation curve.
