Are these track marks after Dermapen normal and what can I do to fix it? (Photo)

if you do not treat this quickly you can be left with hyperpigmentation and "lines" and marks. on the body 2mm is way too deep and you shoudnt be doing that at home In first place. secondly you should be pre and post treatment your skin (see linke to emeragecosmetics.com for proper skincare and cleansers).  I would suggest vivatia foam and cosmelan or enlighten peels long term to get rid of the risk of hyperpigmentation.Hyperpigmentation from any type needs a combination approach of peels like cosmelan,  lasers like clear and brilliant and aerolase or laser genesis, radiofrequency like venus viva, and constant skin care and sun protection.  Bimontly facials with silk peel dermalinfusion is essential to hydrate, exfoliate and infuse vitamins and antioxidants into the skin.  If you have acne you can do additional treatments and peels to get more improvement.  I suggest a formal consultation with an expert in lasers and peels.
