what do derma rollers do
1 answer
Derma rollers, also known as microneedling rollers, are devices with small, fine needles that are rolled over the skin to create micro-injuries. These injuries stimulate the body's natural healing process, promoting collagen and elastin production in the skin. This can help improve the appearance of fine lines, wrinkles, acne scars, and hyperpigmentation. Additionally, derma rollers can enhance the absorption of skincare products by increasing their penetration into the deeper layers of the skin.
