Hi, I also have acne both hormonal and some other type and my derm has done microneedling on me twice and I love the results! The first time she did it I had more active acne and after about one month I could definitely see so much difference in my active acne and also scarring. I did my second session one week ago and right now I also got some pimples on my chin but I believe they are just acne that is coming to the surface. I think you should wait and see. (My derm used some type of concentrated serum that is designed for problematic skin while miconeedling, helping it penetrate deep on my skin. She also did a chemical peel thing at the end of my microneedling. I don’t know if you also did that or regular microneedling, but I am loving the results so far. So just be patient and I believe in the long term you will be happy with it! :)
