Derma Roller for Beard & Hair Growth 0.5mm, Microdermabrasion Tool 540 Micro Needles for Facial, Body & Hair Growth - Includes Storage Case
Really Make A Change - A derma-roller contains hundreds of tiny needles. When in use, these needles create micro-injuries on the skin, which in turn sends collagen and elastin production into overdrive to compensate as it heals.
0.5mm Needle Length - Safe and Painless needle length. Our esthetician-recommended microneedle length (0.5mm) requires firm yet gentle pressure to maximize usage and minimize discomfort. Most Suitable size for Home use.
