Epigallocatechin Gallate (EGCG)
Epigallocatechin Gallate (EGCG) is the most abundant and biologically active catechin found in green tea extract, derived from the leaves of the Camellia sinensis plant. It is a powerful antioxidant and anti-inflammatory compound that has been extensively studied for its therapeutic effects in both medicine and skincare.
In topical formulations, EGCG plays a central role in protecting the skin from oxidative stress, calming inflammation, and supporting a more balanced, even complexion. It is especially beneficial in products aimed at treating acne, redness, photoaging, and environmental skin damage. EGCG is most commonly found in serums, moisturisers, masks, and sunscreens containing green tea extract or standardised catechin blends.
Benefits for Skin
- Acts as a potent antioxidant, helping to neutralise free radicals and reduce oxidative damage caused by UV rays, pollution, and stress.
- Reduces inflammation and redness, making it useful for acne-prone, sensitive, or rosacea-affected skin.
- Helps regulate sebum (oil) production and may inhibit acne-causing bacteria, contributing to clearer skin.
- Supports collagen and elastin preservation by inhibiting enzymes that break down these structural proteins.
- Improves skin tone and texture by calming irritation and enhancing skin resilience.
- May help prevent photoaging and pigmentation issues when used consistently alongside sun protection.
Safety & Toxicology
- Considered safe and non-toxic for topical use in cosmetic formulations.
- Non-comedogenic and well-tolerated by most skin types, including sensitive and acne-prone skin.
- Derived naturally from green tea and often used in vegan, cruelty-free skincare products.
- Should be stored in well-formulated, stable products to preserve antioxidant potency; EGCG can degrade when exposed to air, light, or high temperatures.
- Can be used daily and layered with other actives, including niacinamide, hyaluronic acid, and peptides.
- No known long-term side effects or systemic risks when used topically at cosmetic levels.
