Dermaroller

Dermaroller

A derma roller is a small roller that has a number of small needles on it that you use to make holes in your skin, a process called microneedling. The idea is that these tiny holes can help your skin produce more collagen, a protein that helps with healthy-looking skin. It can also open up your skin to serums and hydration products.[1] Typically, you use this treatment on your face, though you can use it on other areas of your body, particularly areas that have scarring.
