Algenist’s award-winning skincare is based around one hero ingredient: Microalgae. Hailing it the “mother of all algae”, the brand’s team of scientists discovered that this Omega-rich organism produces Alguronic Acid, which has incredible moisture-retaining properties and boosts cell renewal by 55%. The skin benefits are so impressive that the brand promises a renewed and more youthful complexion after just 10 days of using a product.
