Key Takeaways

• Microneedling's History and Mechanism: Developed in 1994, microneedling (also called collagen induction therapy) uses tiny needles to create micro-wounds in the skin, stimulating collagen production and wound healing. This process promotes growth factors and new blood vessels, improving skin texture and potentially enhancing topical ingredient absorption.
• Effectiveness and Applications: Studies show microneedling can improve acne scars (50-80% improvement), stretch marks, wrinkles, and fine lines. It may also help with melasma, potentially enhancing the effectiveness of topical treatments like tranexamic acid or Vitamin C. Combined with minoxidil, it significantly improves hair growth in male pattern hair loss.
• Procedure and Aftercare: The procedure involves cleansing, numbing, applying a hyaluronic acid gel, and using a device to create pinpoint bleeding. Post-procedure care includes hyaluronic acid serum application, optional hydrocortisone cream (for 2-3 days), and mineral sunscreen use (at least for the first week). Makeup should be avoided for two weeks.
• Potential Complications: While newer research suggests lower risk than previously thought, post-inflammatory hyperpigmentation is a theoretical risk, especially for darker skin tones. Applying topical treatments immediately after microneedling can lead to foreign body granulomas (a permanent adverse effect). Skin infections are also possible if proper hygiene and sterility aren't maintained.
• Precautions: Microneedling should be performed by a professional, not at home. It is not recommended for those with active acne, recent sun exposure, or herpes outbreaks.
