Enhance your dermarolling routine with the Micro Needle Derma Roller 0.5mm. Equipped with 540 stainless steel micro-needles, this roller is designed for home use. Regular use helps to create micro-channels in the skin and scalp, promoting the absorption of hair growth treatments and improving the appearance of light scars, pigmentation, and uneven texture. Use it once every 2-4 weeks to allow the skin and scalp to recover. It is PETA approved, cruelty-free, and vegan.
