Crystal Derma Rollers Are Inefficient
Derma rollers are an at-home treatment for micro-needling. Most derma rollers have tiny needles that dig into the skin, which can increase skin collagen by 400%, according to a 2008 study. Crystal derma rollers don’t have enough texture to recreate this effect.
Medical aesthetician Cynthia Rivas says that, at most, crystal rollers can lower puffiness and fine lines. But most people don’t use them correctly, and many don’t come with instructions. You’re better off buying an authentic derma roller.
