Nannochloropsis Oculata Extract description

_Nannochloropsis oculata_ extract is a plant derived microalgae used in skin care for its antioxidant and humectant properties. _Nannochloropsis oculata_ extract is rich in fatty acids, like linolenic acid, hydrating polysaccharides and antioxidant carotenoids. These compounds work together to soothe, hydrate and restore skin, providing balance and, in the long term, a strengthened barrier. The main carotenoid present in _Nannochloropsis oculata_ extract is zeaxanthin, which functions as an antioxidant to prevent pro-aging external damage that pollution and UV rays often cause. It also helps promote an even skin tone. Cosmetic ingredient suppliers tout _Nannochloropsis oculata_ extract as an effective skin-tightening agent; however more research is needed to substantiate this claim. When formulated in a blend with supporting ingredients, suppliers recommend using this ingredient in concentrations between 1%-5%. Due to its antioxidant content, products that contain _Nannochloropsis oculata_ extract should be housed in air-tight and light-proof containers, so the ingredient doesn’t degrade.
