When I tested this product, I had almost given up hope that it could have a positive effect on my skin, since I have had bad experiences with many other products. After about a month Effaclar my skin was very clean, no trace of acne or pimples. Also worth mentioning is the long-term effects of the product, that is, the effect wears off, as with many other creams or washing lotions, not sometime after. I can absolutely recommend Effaclar!
