TLDR Green tea may help with various skin conditions and protect the skin when taken orally or applied topically, but its effectiveness is not always proven.
In 2013, a review of 20 in vitro, in vivo, and controlled clinical trials was conducted to assess the effectiveness of green tea in dermatology. The results suggested that oral administration of green tea could be effective in scavenging free radicals, preventing cancer, reducing hair loss, and slowing skin aging. It was also found to protect against adverse effects associated with psoralen-UV-A therapy. Topical application of green tea extract showed potential effectiveness for conditions such as atopic dermatitis, acne vulgaris, rosacea, androgenetic alopecia, hirsutism, keloids, genital warts, cutaneous leishmaniasis, and candidiosis. However, the efficacy of oral and topical green tea was not always confirmed.
