    TLDR Microneedling is effective for skin rejuvenation and various skin issues, but more research is needed to confirm its safety and effectiveness.
    The document reviewed the use of microneedling for various skin conditions, highlighting its minimal invasiveness and its role in stimulating collagen and elastin production. Studies cited within the document showed positive outcomes for skin rejuvenation, scars, acne, hyperpigmentation, and alopecia, as well as for enhancing drug delivery through the skin. Notable findings included a split-face trial with 15 females that reported improved skin parameters, a study with 113 patients showing enhanced wrinkle and skin laxity reduction, and a study with 100 men where microneedling combined with minoxidil outperformed minoxidil alone in hair count after 12 weeks. Despite these promising results, the review called for more randomized, controlled trials to solidify the evidence of microneedling's effectiveness and safety.
