“Matcha is a finely ground powder from a uniquely processed green tea, thought to be super high in antioxidants” — specifically epigallocatechin gallate, or EGCG — said Dr. Leah Ansell, a cosmetic, medical and surgical dermatologist and an assistant professor of dermatology at Columbia University.
Though green tea has long been included in skin care products, matcha specifically is a newer ingredient in the market. “Catechins found in green tea and in super high concentrations in matcha-type green tea are thought to be the mechanism for protecting and repairing the skin,” Ansell said. The idea that matcha is a powerful skin care ingredient is based on studies of topical formulations of green tea, which “have shown significant reduction in skin cancer when applied in mice,” she said.
“We do know that when matcha is in tea form, the concentration of EGCG is 137 times greater than the amount of EGCG in other forms of green tea and at least three times higher than the largest literature value for other green teas,” Ansell added. “As a skin care ingredient, [matcha] is thought to have protective effects to fight free-radical damage, have anti-inflammatory powers and potentially ... reduce the appearance of sun damage.”

It has active ingredients that target acne specifically — sulfur and salicylic acid — but also contains topicals that dry it out, such as isopropyl alcohol, zinc oxide, and talc. This combo is great because some of the ingredients can be quite irritating to the skin, so the combination helps to combat adverse side effects.
