Needs understanding of what it does and patience

I don't use this product often, but really like it. A few times over the past years I felt a burning sensation and saw red patches on my face, but letting things calm down, putting some rich moisturizer on top helped. Now that I look back, I was probably applying it a day after lactic acid or Vit C + resveratrol treatment when I saw irritation. So now I space it with days of mere moisturizing, so my skin doesn't overact. I love this product, the next day my skin is even and blemish-free. That said, maybe it's not for everyone - seeing other reviews.

This stuff is impressive!

I used this years ago for age spots on my arms and it worked great. Bought another bottle to use on a mole that had discolored and doctors said was a common condition- it was flaky and dark. After a few months of using this, its back to flesh colored and much less flaky. This stuff is impressive!
