Scenedesmus Rubescens Extract

What Scenedesmus Rubescens Extract is & what it does

Scenedesmus Rubescens Extract is derived from a species of freshwater green microalgae. In skincare and sunscreen formulas it is used as a conditioning and antioxidant-rich botanical ingredient, valued for the carotenoids, proteins, and polysaccharides that microalgae naturally accumulate. One notable property is that this alga produces protective pigments in response to light stress, which is why microalgal extracts are often included in formulas marketed for environmental protection.
