Titanium Micro Needle Rollers are engineered from pure titanium alloy and feature gold-plated needles. Titanium Rollers offer superior durability and are optimal for use on the stomach, thighs, and back. Skin Roller therapy (also referred to as skin needling, dermal rolling and micro-needling) is performed with 192 high-grade medical stainless steel micro needles mounted on a small wheel that gently rolls over the face and painlessly penetrates the skin’s upper surface. This simple but revolutionary treatment provides multiple benefits.
