a derma roller (a type of microneedling) uses a handheld device with tiny needles to create controlled micro-injuries in the skin, triggering its natural healing response to boost collagen and elastin, resulting in smoother, firmer skin that reduces fine lines, scars, stretch marks, and pores, with minimal downtime and enhanced product absorption. A clinician applies numbing cream and rolls the device over the skin, causing mild redness that subsides in a few days, with results improving over weeks as new collagen forms.
