The Derma Roller System with 0.5mm needles is a professional-grade microneedling device designed for at-home skincare treatments. This system helps improve skin texture, reduce fine lines, and enhance the absorption of skincare products through controlled micro-injuries to the skin surface. The device should be used with proper sanitization - clean with alcohol before and after each use. Roll the device over the desired treatment area 4-5 times in different directions (horizontal, vertical, diagonal) as shown in the product instructions. Avoid excessive pressure and do not use on inflamed or irritated skin. As this is a personal care device that creates micro-injuries in the skin, proper cleaning and careful usage according to instructions is essential for safety.
