Microneedling and Platelet-Rich Plasma: A 2018 Study on Effectiveness for Skin and Hair Conditions

The document from 2018 examines the effectiveness of combining microneedling with platelet-rich plasma (PRP) for treating skin and hair conditions. PRP, which is rich in growth factors, and microneedling, which creates microchannels in the skin, are shown to work synergistically to enhance tissue repair and collagen production. The document cites increased skin flap survival in animal models and higher patient satisfaction for acne scar treatment when these methods are combined. It also provides guidelines for patient selection, procedure, and care, noting minimal complications. Additionally, the document explores microneedling's optimal needle depth and timing for topical application, with small studies indicating aesthetic improvements up to 12 months post-treatment. However, the addition of PRP post-microneedling may not offer significant extra benefits. Microneedling is highlighted as a promising technique for skin rejuvenation and potential medication delivery.
