TLDR Thyroid hormone may speed up wound healing and hair growth, but more research is needed to understand its role in skin repair and use as a treatment.
The document reviewed the role of thyroid hormone, particularly triiodothyronine (T3), in skin physiology, noting its ability to accelerate wound healing and hair growth in rodent models through topical application. It also discussed the use of topical thyroid hormone in treating human skin dryness and the skin manifestations of thyroid diseases like hypothyroidism and thyrotoxicosis. The review concluded that although the direct action of thyroid hormone on skin cells has been established, more research is necessary to fully understand its role in skin repair and its potential as a treatment.
