great serum [SEP] this is a very good serum for my face i have acne around my chin and cheeks and any time i use a new product i get an outbreak i am surprised to say this did not give me an outbreak i have dark circles that are hereditary and i used it under my concealer and it helped reduce its appearance a little bit from what i can tell because i do not normally put anything under there except the concealer very satisfied with this product great consistency and goes on sheer no white residue from what i have seeni received this product at a discounted price in exchange for an honest and unbiased review
