I've had acne for 2 years and I ended up going To my doctor which he first told me I had severe acne and recommended a benzoyl peroxide which did nothing and didn't help me at all I was very sad. Then I went back to my doctor a couple months after trying many products like proactive later on I returned to my doctor and he told me I had cystic acne and told me to go to a dermatologist but he also prescribed me minocycline 100 mg caps and I was curious to know if it actually works and I just need something to work by now.
