unless a product like this is used for a long period of time [SEP] the serim is absorbent i have been using serious skin care for years and have sadly seen the quality of its producy decrease the company heads now seem interested only in what is trendy and not product results unless a product like this is used for a long period of time one cannot tell whether or not it works i use the c line for prevention and do not currently have wrinkles i like the fact that ssc products can be used sparingly these serums take a few minutes to be absorbed
