Microneedling, or collagen induction therapy, uses tiny needles to create controlled skin injuries that stimulate the body's natural wound healing process, promoting collagen and elastin production to improve various skin concerns such as wrinkles, scars, and hair loss. While generally considered safe and effective, it may cause side effects like skin irritation, swelling, and in rare cases, infection. Full results can take months to manifest, and certain individuals may not be suitable candidates for the treatment.
