How to use derma roller

Only way to use it, is if a professional does it for you. Dermarolling at home is dangerous as you could easily damage your skin by using the roller, additionally it’s really difficult to clean so you’d essentially be making holes in your skin and filling it with gunk and bacteria, opening the door for acne and infection

I have one. it’s… okay. it’s most useful benefit to me is that it helps my products sink in more effectively. for acne scars, I don’t think an at home is the way to go. the needles are quite small and not deep. I’ve done more damage to my face with fake nails tbh. for acne scarring I think you’ll need an actual professional session. they use longer needles that I obviously don’t recommend using at home.
