I have been using the Clarins Bright Plus Intensive Brightening Smoothing Serum religiously - morning and evening. After cleansing and toning I squeeze one pump on to my finger and dot it evenly on my face. I was happy to know that a little goes a long way with this serum. I also liked the fact it did its fair share in providing moisture and not simply absorbing into nothingness. It hasn't caused any breakouts and once again I'm super thrilled.
