When treating acne try using green tea, a person can apply products containing green tea topically on the skin. Alternatively, they can take supplements orally.
Researchers have primarily looked at green tea for acne as a topical application or as a supplement. Most studies have shown the positive effects of using either of these methods.
Few studies look at the effects of drinking green tea as a treatment for acne. The main issue is that researchers have not determined the effective dose, so the quantity of compounds in a drink may not be enough to have positive benefits for acne.
If someone is interested in drinking green tea, they should consider brewing their tea at home. Premade green tea, such as iced green tea in bottles or cans, often contains additives and sugar. This could negate some potential benefits.
