i like it but watch out for sesame oil and sweet almond oil if you have allergies [SEP] here is a little background i am fair skinned middle aged and my skin tends to be sensitive and somewhat oily i have fine lines but my dermatologist thinks i have great skin for my age i use cetaphil facial cleanser and whatever moisturizing samples i have on hand from glossy box i do not work outside the home and do not spend a lot of money on my face the collagen booster serum claims to reduce the appearance of fine lines on the skin and to plump up the skin with collagen i really have not noticed any difference using this or using any other moisturizer or serum what i would warn you about is that it contains both sesame oil and sweet almond oil so if you have nut allergies avoid this product would i spend money on this product at over for one ounce probably not
