Dermaroller 540 titanium needles, 1.0 mm needle

What is the derma roller? The derma roller is the general name for cylindrical skincare devices, made of titanium needles ranging in thickness from 0.5 to 2.5 mm. These devices cause limited damage to the surface of the skin, while at the same time opening tiny channels underneath, which stimulates collagen production in the skin, and significantly increases the effectiveness of the skincare products used.
