Was this caused by cystic acne? You could try silicone gel or see a dermatologist for something like steroid injections to flatten the scars. Is your acne over?

@blastoise

yes , back when I was in high school I have these huge cystic acne in my nose and I picked on them. I'm considering those injections but I read some articles that there's a chance that it will comeback after it flattened. My acne isn't actually over cuz I'm still getting bumps as you can see in the pic I have alot of pimple scar

Hi, I've been experiencing the same problem. I've tried the steroid injections before, it will surely flatten the bumps but it's not permanent. So basically, after a couple of months, you need to go back to your derm to do it again. It cost a lot of money.
