In order to provide good feedback, at first I used it night and day, then I saw dry areas on my cheeks then decided to just put it on at night and I improved, mention that the product is good but not for me because I bought it for my problems of Pigmentation and this product is an illuminator does not serve me for pigmentation, my skin is soft, the pores are closed and the skin looks clearer but the spots are not removed, I can recommend it to achieve a smooth and illuminated skin but if you want something like me for pigmentation no. I'm 51 years old with combo skin
