I first started this May and just stop this October. Starting from 10mg a day for a month, then 20mg a day for second, 30mg for next month, and last 2 months i took 40mg a day. Overall, my acne is improved much better from 10-20 active inflammatory acne to none in last 2 months of course. However, it is been a month since i stop. Some acne starting to comeback. 2-3 that I found, and also oily face too. The scar is the same maybe even noticeable than before. Should I continue? Btw, I am 60kg.
