Green Tea (*Camellia sinensis*) is much more than a beverage. In the world of clinical skincare, it is one of the most well-researched botanical ingredients, famous for its unmatched antioxidant profile. In Ayurveda, while not a native Indian plant, its properties are classified as Kashaya (Astringent) and Lekhana (Scraping), making it excellent for clearing toxins and reducing excess Kapha (oiliness).
The secret to Green Tea's power lies in a specific group of polyphenols called Catechins, most notably EGCG (Epigallocatechin-3-gallate). EGCG is a powerhouse that fights DNA damage from UV rays and reactivates dying skin cells.

EGCG: The DNA Protector
EGCG is the most potent catechin found in green tea. Clinically, it has been shown to neutralize free radicals—the unstable molecules that damage healthy cells and lead to premature aging. More impressively, studies suggest that EGCG can actually help repair DNA damage caused by UV exposure, making it an essential layer under your daily sunscreen.
6 Clinical Benefits of Green Tea
- Anti-Aging: Inhibits the enzymes that break down collagen and elastin.
- Oil Control: EGCG is anti-androgenic, meaning it can lower lipid levels and reduce sebum secretions in the skin.
- Anti-inflammatory: High levels of polyphenols reduce the redness and swelling associated with acne and rosacea.
- Treats Puffy Eyes: The caffeine and tannins in green tea help shrink blood vessels around the eyes, reducing dark circles and "bags."
- Fights Skin Cancer: By promoting DNA repair and providing UV protection (internally and externally).
- Soothes Irritation: Helps calm the skin barrier after chemical peels or harsh exfoliants.
Topical vs. Oral Consumption
Should you drink it or wear it? The answer is both.
- Drinking: Provides systemic antioxidant protection and boosts metabolism, which reflects in a clearer complexion.
- Topical: Concentrates the catechins directly where you need them. Topical green tea is more effective for immediate oil control and reducing localized redness.
