Microneedling frequency generally depends on skin type, treatment goals, and whether the procedure is done professionally or at home. The common recommendation for professional microneedling is every 4 to 6 weeks, which allows the skin time to heal and rebuild collagen. For deeper treatments like acne scars or wrinkles, sessions might be spaced 4 to 8 weeks apart, with a series of 3 to 8 treatments typically recommended for best results. Sensitive skin may require longer intervals of 6 to 8 weeks between sessions. For at- home microneedling, using shorter needle lengths, treatments are usually safer every 2 to 4 weeks with lower needle depths. After achieving desired results, maintenance sessions can be done 2 to 3 times per year. Overdoing microneedling by doing it too often can cause skin irritation, inflammation, and damage to the skin barrier due to insufficient healing time.
