The product reduced the redness on my face for the first 2 weeks, then my face got full breakout constantly since then. This was not too surprising because their acne treatments are made of antibiotics, and not all acnes are composed of the same microbes. They gave me the formula by just looking pictures of my face and tried to guess what kind of acnes it was. Secondly, microbes become resistant to antibiotics too. This is probably part of the reason it stopped working for me. When I asked them that, if I find a formula that works for my skin, whether I have to keep using it for the rest of my life. And the answer was yes. At this point I started to feel uncomfortable with the idea of putting antibiotics on my face for the rest of my life. In my case it was clindamycin and azelaic acid, which are antibiotics to treat severe acnes. But I told myself, I'm ready half way through with this subscription. Maybe I would just find a formula that works, let it clear my skin, then stop it. Another reason I carried on was because they advertised that it would take 3 months to see the results. I was on the treatment for 4 months but nothing had improved. Why 4 months? The answer is they charge every 2 months for the subscription, which means customers would be on the hook for 4 months before they can definitely say whether a formula works or not. It is true that nobody made me pay, but I felt as if I was pressed to pay for 4 months in stead of 3 months. And if I chose to switch the formula, I would have to pay for another 4 months. This is unfair for the customers. When I canceled my subscription, they asked if I wanted to add pills. I thought this is very interesting because if I wanted a prescription I would have seen a doctor for it, not from somebody who never examined my condition in person. Having said that, I think it might be a good thing that this product did not work on me. I realize now that if I have to be on tropical antibiotics for the rest of my life, I would rather not do it because it is not supposed to be the way my body would function naturally.
