I don't know why I haven't tried this before but I can tell after 15 years of battling against acne this is the only skin product that has actually ever helped me! At first I was sceptical because no medication ever worked for me and every skin treatment had left my skin feeling irritated and dry but I'm so glad that I finally bought this! I use just 1-2 drops of this mixed with my toner every day and just in one week I can already see a huge difference in my skin! The redness has completely gone away the old acne spots are healing and I haven't had any new acne spots appearing which is super rare for me! I'm so amazed! This is the best product I've ever tried for my acne!
