Love all these products. I was using all the serums and although there were benefits I was still getting spots after a year. I originally thought my cleanser would be fine, but eventually Got Dr Sam’s one, honestly made the biggest difference having a really good cleanser, cause she’s right, without a decent cleanser all the serums don’t work properly. After that it’s been two months of cleanser roughly and my 8 years of acne is finally healing. So crazy to think it was the cleanser and not the serums I needed to change. Before was double cleansing with oil as I wear make up and then a water based cleanser. No more. Also save a lot of time only using one cleanser. Thanks.
