Hello,

I have came across different reviews about how different retinol products have helped them with their acne, but what is it actually doing on the skin? Is it helping with the actual acne or with the reddness? Also, I have sometimes read that retinol products cannot be used together with exfoliants like AHAs and BHAs?

Any reliable inforamtion would be appreciated, as i have read a lot of cotradicting information about this.
