Results from microneedling typically begin to appear within 2-3 weeks as the skin starts to heal and collagen production increases. Full results, including improved skin texture and reduced scarring, can take 4-6 weeks or longer, as collagen remodeling continues. Multiple sessions are often recommended for optimal and long-lasting improvements, with noticeable changes usually seen after 3-6 treatments, spaced about 4-6 weeks apart.
