Glossary
An extract from the unfermented leaves of Camellia sinensis that is one of the most well-researched botanical ingredients in skincare. The primary active compound, EGCG (epigallocatechin gallate), has demonstrated potent antioxidant, anti-inflammatory, antimicrobial, and photoprotective effects in numerous clinical studies.
EGCG is one of the most potent natural antioxidants identified by science. Its free radical scavenging capacity exceeds that of vitamin C on a per-molecule basis. When applied topically, EGCG neutralizes UV-generated free radicals, reduces inflammatory signaling, and has been shown to reduce UV-induced DNA damage by up to 66 percent in some studies.
Beyond photoprotection, EGCG inhibits the enzymes collagenase and elastase (which break down structural proteins), blocks tyrosinase (reducing hyperpigmentation), and reduces sebum production (beneficial for oily and acne-prone skin). This wide spectrum of activity makes green tea extract arguably the most versatile botanical in skincare.
Green tea extract is used in serums, moisturizers, eye creams, and sheet masks. For maximum benefit, choose products with stabilized EGCG (it oxidizes easily) in airtight, light-protected packaging. Products in clear jars have likely lost significant EGCG activity from light exposure.
A simple DIY approach: brew a strong cup of green tea, cool it, and use as a toner or compress. Alternatively, combine cooled green tea with raw honey for a powerful antioxidant and antimicrobial face mask.
Yes, with strong scientific support. Green tea's EGCG protects against UV damage (the primary cause of aging), preserves collagen and elastin, and provides antioxidant protection against environmental aging. Multiple clinical studies show improvements in skin elasticity and wrinkle appearance with topical green tea use.
A cooled green tea bag applied as a compress provides genuine antioxidant and anti-inflammatory benefits, especially for puffy eyes. For sustained benefits, formulated products with stabilized green tea extract are more effective because the active compounds are preserved and concentrated.
Both provide benefits through different mechanisms. Drinking green tea delivers systemic antioxidant protection. Topical application provides targeted skin-surface protection. For maximum benefit, do both.
