This is said to be a high-performance, science and plant-based product delivering visible results in reducing deep lines and wrinkles, without causing irritation. This serum is incredible. I have used many serums, moisturizers, etc., in the past trying to find one with the right active ingredients that will help the early signs of aging as I just turned 30. When I started using the Algenist Retinol Serum, I immediately knew I found the holy grail after using this after only one time. This helps firm, reduce puffiness, and smooth fine lines. I noticed my skin feels brighter. The texture of the serum is lightweight and gentle, a little goes a long way. It absorbs seamlessly and my fine lines have started to slowly fade. Also, since this product contains retinol, do not forget to wear your sunscreen! Ultimately, this has given me a brighter, healthier looking glow and I am enthusiastic about continuing to use this to see ongoing results!
