All the negative reviews are here for a reason. After a few months of using their products, I developed a rather severe rash on my face. I have used retinol creams before, as well as glycolic acid with no issues ever. After using these creams I got a severe case of dermatitis that has gone on for months now. My skin is so irritated that I can’t use ANYTHING on it anymore, not even moisturizer or sunscreen. When I contacted the provider, they just kept trying to push more creams on me, (free of charge) even when I told them that I’d had a rash on my face for over 4 months. I feel like my skin is permanently damaged from using these products. it’s very distressing. The whole system of communicating through their website is inefficient, and you get the feeling that you are speaking to bots and not people. I had to write so many emails to them and they still couldn’t seem to understand that my skin is reacting badly to this product, so please stop sending me any more creams- even if they ar e free! Highly unethical. I have no other option than to cancel my subscription.
