TLDR Microneedling is a safe and effective way to improve various skin conditions with minimal side effects.
The document from 2018 reviews the effectiveness of skin microneedling for treating various skin conditions, including photoaging, scars, pigmentation changes, and alopecia. Microneedling stimulates collagen and elastin production and can be enhanced by combining it with other treatments. Studies showed significant improvements in skin conditions with microneedling, such as a reduction in wrinkles, improved skin elasticity, and better outcomes for stretch marks and alopecia when combined with minoxidil, with 82% of subjects reporting over 50% improvement. Microneedling also showed promise in treating melasma and vitiligo, with one study reporting a 44.41% improvement in melasma when combined with tranexamic acid. A study on vitiligo with 25 patients found it effective when combined with 5-fluorouracil or tacrolimus. For dark circles and acne scars, combining microneedling with other treatments like trichloroacetic acid peels or platelet-rich plasma (PRP) showed significant aesthetic improvements. The document concludes that microneedling is a safe and effective method for skin defect treatment with minimal side effects, although long-term effects are unknown and proper aftercare is necessary.
