Micro Needling 540 Roller Derma Roller Professional Titanium Dermaroller 0.2/0.25/0.3mm Hair Regrowth Beard Growth Treatment

Derma rollers are used to promote collagen production, which can help reduce the appearance of fine lines, wrinkles, and acne scars. 

They are also used to stimulate hair follicles on the scalp to promote hair growth. 

The device creates micro-channels in the skin, which can enhance the absorption of skincare products. 

Derma rollers come in various needle sizes, and it is important to sterilize the roller with alcohol before and after use.
