Microneedling

Microneedling is most often discussed for the face, where fine needles on a roller or a motorized pen are passed over the skin to address atrophic acne scars, lingering post-acne marks, enlarged pores, rough texture, and dull tone. It is also used on body areas such as scars or stretch marks. Because the needles break the skin, it is considered a medical procedure rather than an ordinary cosmetic facial.

Improvement, when it comes, is gradual: repeated micro-injuries prompt the skin to remodel collagen, softening shallow scarring and refining texture over months. Microneedling does not lift sagging tissue, cannot fill deep ice-pick scars on its own, and its effect on pigmentation varies between individuals. Radiofrequency microneedling and gold RF microneedling, which deliver heat energy through the needles, are different treatments covered in their own entries.

The principle is controlled injury: thousands of micro-channels trigger the skin's wound-healing response, which includes producing new collagen and elastin. At the appointment, the clinician cleanses the skin and usually applies a topical numbing cream, waiting for it to take effect before working over the area section by section. During treatment most people feel scratching, pricking, or warmth—more noticeable over bony areas such as the forehead and jawline—and pinpoint bleeding can occur, especially at deeper treatment settings.
