I've only been using this product, along with the Youth Recovery Serum at night, for less than two weeks so this is a very preliminary review. This lotion-serum is extremely lightweight. I apply it in my morning routine after two other serums, and it plays very well with them. There is no pilling, stickiness or irritation. I'm not a fan of pure ascorbic acid so the Vit C derivative in the lotion suits me very well. I also appreciate that the serum does not have any added fragrance, although it does have a very faint, odd scent, which I believe comes from the ferulic acid but I'm not sure. It's not enough to bother me and goes away after applying sunscreen. Too soon to tell if this will help with my hyperpigmentation but so far it's been a delight to use and I will continue to use this in my morning routine.
