I would guess your skin is already fully developed at your age. I'd actually think you'd have better healing capabilities the younger you are. If you don't want to use a dermapen/roller you could still use AHAs which really help hyperpigmentation.

Are you still having breakout? If not, I would suggest using the dermaroller/pen. If you still have breakout avoid those areas. Many people on the forums have regims as to how they use their dermaroller/pen for a clear face. Search though threads to get a better understanding on how and when to use the dermaroller/pen.

Thanks for the response guys. I'd rather not do it myself, afraid that I would mess something up. There is a clinic nearby where they do them. Regarding the breakouts, I haven't had breakouts in a long time.

Thanks for the tip regarding the AHA, I will look into it.

Anything else is appreciated!
