Hi, i'm 22 and have been used the regimen: cleanser, treatment, moisturizer for almost 2 years, but i dont use itcontinuously. Whenever my skin got clearer, i stop using it. Then recently, my acne comes back so i decided to use the regimen again, this one is the 3rd one already. However, this time i'm experiencing everything that a person will experience when they use the regimen for the first time. i'm really confused because i thought once your skin got used to benzoyl peroxide, you won't experience from redness, irritating, peeling and flaking again. I'm nearly done with the 2nd week. Did someone experience those same things as me? Thank you very much!!!
