TLDR Microneedling may help treat some autoimmune skin conditions, but more research is needed.
This scoping review evaluated microneedling as an adjunctive treatment for autoimmune skin conditions such as alopecia areata, vitiligo, and dermatomyositis. In 14 studies, microneedling enhanced drug absorption and promoted hair regrowth in 290 out of 360 alopecia areata patients, and facilitated repigmentation in 329 vitiligo patients when combined with other therapies. A single case report suggested benefits for dermatomyositis. While microneedling showed promise, the studies were limited by small sample sizes and short durations, indicating a need for further research to determine long-term safety and efficacy.
April 2024 in “Skin research and technology” Minoxidil with triamcinolone acetonide is more effective for mild alopecia areata when injected with microneedles than when applied topically.
September 2022 in “International Journal of Trichology” Both microneedling and injections are equally effective for treating alopecia areata.
