Green tea (Camellia sinensis) has been used traditionally in many cultures, particularly in Asia, for general wellness, but its use specifically for skin health is increasingly supported by scientific research. Green tea is rich in polyphenolic compounds, especially catechins such as epigallocatechin gallate (EGCG), which possess strong antioxidant and anti-inflammatory properties.

Scientific studies have demonstrated that topical and oral use of green tea extracts can provide benefits to the skin. Research published in peer-reviewed journals reports that green tea polyphenols can help protect the skin from ultraviolet (UV) radiation-induced damage, decrease the formation of free radicals, and reduce inflammation. For example, a 2007 review in the Journal of the American Academy of Dermatology noted that green tea polyphenols demonstrate photoprotective effects and may be useful in preventing skin disorders related to UV exposure.

Additional studies have explored green tea’s role in managing acne due to its antibacterial and sebum-reducing effects, as well as its potential for improving skin elasticity and hydration. However, while results are promising, many studies are small or preliminary, and more large-scale clinical trials are needed to confirm efficacy and determine optimal dosing and methods of application.

In summary, green tea is scientifically supported as a beneficial ingredient for skin health, particularly for its antioxidant, anti-inflammatory, and photoprotective effects, meriting a moderate evidence rating.
