This high-performance serum combines the dual action of time-released retinol and the retinoid-like benefits of Fermented Green Microalgae to diminish the appearance of deep lines and wrinkles without irritation. Algenist's research has derived a plant-based retinoid-like ingredient from Fermented Green Microalgae that works effectively, yet gently, in combination with vegan retinol. Skin's texture is improved by promoting accelerated skin cell turnover. A blend of AHAs, BHA and PHA also boosts the exfoliation of skin's surface layers to reveal smoother, more even skin texture and tone. Patented Alguronic Acid and humectants plump skin for a natural radiance. Suitable for daily use. Apply to clean skin on the face and neck. Follow with a moisturizer of your choice. This product is shown to be non-irritating but retinol beginners may want to gradually work this into their skincare routine. It is recommended that an SPF is used during the daytime in case of increased photosensitivity. Avoid direct contact with eyes.
