I have been testing the Pure Niacinamide 10 serum from La Roche Posay and coming to the end of the bottle nowโฆ.shame! Really impressed with it! I have been using it morning and evening without skipping! I definitely feel that my skin is brighter and my pigmentation has faded a lot! My skin feel softer to touch to. I love the glow it gives you after applying! ๐
