This product contains lots of vitamins (including vitamin c ascorbic acid) and ingredients such as Niacinamide, Glycerin and Panthenol. I didn't have any blemishes or spots when I was trying this product so I did not observe any obvious improvement to pigmentation. However, the product sinks into my skin pretty well and does not leave a tacky finish. It leaves my skin feeling nice and plumped. I think this product has lots of potential and is worth the try.
