handheld device with tiny needles that stimulate collagen production
A Dermaroller, also known as a microneedling roller, is a handheld device equipped with numerous tiny needles that create micro-injuries on the skin's surface when rolled over it. This process stimulates collagen production and enhances the absorption of topical treatments, making it useful for improving skin texture, reducing scars, and potentially promoting hair growth in cases of alopecia.
