The product was effective within the first two weeks of me using it. It doesn’t have a super chemical smell and it was very gentle and soft on my skin while it got rid of acne super fast. My skin improved drastically and the product did not damage it nor did it make it dry or ashy/ scaly. One product= easy to apply and there isn’t a huge priocess that has to go into it all you do is wash your face with almost any soap and apply the curology after and it does it’s magic over night. It was also really nice that it added a little extra hydration to my skin so during the winter I didn’t wale up with really dry or irritated skin. Really recommend the product if you can afford it. It arrives within a week and most of the times I wasn’t even done with the current bottle before the new one arrived. 10/10
