I have cystic acne, oily and sensitive skin with large pores so now since that's out the way. Also, I was one dermatologist visit away from accutane. My dermatologist put me on Tretinoin Cream & Minocycline for years. This product is AMAZING. It improved my texture, made my pores shrink and overall improved my skin tone. I saw results as fast as 4 days and I will always have this in my regime. Because I want flawless skin I'm thinking about going up to 20%, but not anytime soon. This is sooo worth it, I recommend it.
