I picked up this serum after Christmas when my skin was looking a little dull, and it has been true love ever since. I read multiple articles about the benefits of serums (bright complexion, reduced fine-lines, etc..), and thought this might be a quick fix. I choose Clinique Custom-Repair Serum because I've always trusted their products. I love this product because it leaves my skin feeling refreshed without the greasiness some serums and creams can leave behind. I apply it twice a day, and have noticed an overall smoothness and brightness to my complexion over the last 2 months. It is great for combating winter dryness, but I'll be using this product year-round.
