What derma-roller and how often for my acne scars?

[260152]

Hiya, I have no idea what size dermaroller I should buy and how often I should use it so would appreciate any advise. Thanks

Ps-I'm also unsure what type of acne scars I have and how bad they are so any advise on that would also be helpful

Use a regular 1.5 mm dermaroller and a 1.5 mm dermastamp. During the same session (every three weeks), stamp the scars and then roll them.
 
You can also try inducing intensive peeling by applying the A-Ret cream (we sell it) right after dermarolling (it stings and it irritates the skin). Do a test patch first to see how your skin reacts.
 
You can read about it in this forum thread (reply 25 from Cesamaddictaol and my reply 26):
