If you love antioxidants this serum is for you. It is chalked full of vitamin C, coffee, green tea and other goodies. It goes on smooth and absorbs very quickly. It is a dark brown colour due to the coffee but in blends in well on most skin tones. I really like using it under sunblock because it really helps alleviate some of the chalkiness and it layers very well. I have noticed a marked improvement in the texture and health of my skin over a short period of time and I will definitely buy it again. My only complaint: there is a silicone in it. Granted it is really far down the ingredient list but I am really not a fan. My friends and family have also complained about the smell of the product. It doesn't bother me at all and goes away quickly but my aunt swore she could never put this stuff on her face. Too bad for her!
