A derma roller, a micro-needle roller or skin rolling device, is a handheld skincare tool. It consists of a cylindrical device with a handle and a roller head that is covered with tiny needles, typically made using reactive ion etching on silicon or high-quality stainless steel. It pierces the skin’s surface to help stimulate collagen formation, thereby improving the appearance of fine lines and scars.

Common Mistakes to Avoid When Using a Derma Roller

The process involves a series of passes over the face with the device, starting from the forehead and moving down to the cheeks and chin, while applying gentle pressure. You may use a numbing cream to make the procedure less painful. The derma roller should be properly disinfected before every use to prevent any infection. To sterilize it, spray the device with an alcohol-based solution and wash it. It is best to use the device at night when the skin is more resistant to bacteria.

Studies have found that the micro-needling process activates platelets and promotes blood vessel growth, helping to treat pattern hair loss, as well as severe alopecia areata (AA). It is recommended to combine this treatment with Minoxidil to enhance the results.

If you decide to try derma rolling at home, it is advised that you avoid harsh cleansers or products with AHAs or BHAs as these can irritate the skin. You should also skip hot showers or baths and drink plenty of water to hydrate the skin.
