Most people need 3 to 6 microneedling sessions, spaced about 4 to 6 weeks apart, for best results. You may start noticing improved skin clarity and freshness within a week after the first treatment, with results continuing to build over time as collagen production increases. Mild concerns may need fewer sessions, while deeper scars or wrinkles may require more. Maintenance treatments every 6 to 12 months can help maintain long-term results.
