What do you recommend to remove acne scars and acne pits?

Dermabrasion. I remembered using the finest wet sandpaper to smooth out my acne scars when I was a teenager. I did this very gently and removed no more than 1 layer of skin at a time. I repeated this once a week until the scar was gone.

dermabrasion does help, but honestly, from experience, it's best to simply go to a dermatologist for your dermabrasion. Too many kits you can get in the markets don't seem particularly affective in my opinion.
