I've been using this product for 2 weeks, expecting little to no results but I was surprised that it's cleared most of my face from the little breakouts I had. My chin and nose area had little red bumps of acne under the surface of the skin. I used this serum religiously every night and day. Now, you can barely see the texture on my skin. My face is very oily but this serum doesn't congest my pores or leave an oily residue. It's actually pretty cooling on application but the scent threw me off at first. It smells like medicine but goes away quickly. By far, the best skin care product I've tried.
