Microneedling is a cosmetic procedure that involves multiple pokes to the skin with tiny sterilized needles. The small wounds cause your body to create more collagen and elastin, which heal your skin and create a younger appearance. This treatment is also called ‘collagen induction therapy.
Microneedling is effective in treating minor scarring related to acne, wounds, and aging. Multiple treatments spaced 4-6 weeks apart will reveal brighter, firmer skin, too. Microneedling is far more effective than at-home rollers, with minimal downtime.
