Topical green tea extract is derived from green tea leaves and contains potent antioxidants, primarily catechins like EGCG, that provide various skin benefits. It protects against free radical damage, reduces inflammation, may improve acne, offers some UV protection, and can aid wound healing. It's generally considered safe for topical use, but skin irritation or allergic reactions are possible. Proper concentration in formulations and patch testing are essential.

Production Process
Green tea extract for topical use is typically produced by extracting active compounds, such as catechins (particularly EGCG), from green tea leaves using solvents like water, ethanol, or a combination of both. The extract is then concentrated and purified to remove unwanted components. The resulting extract is often standardized to a specific percentage of catechins or EGCG.

Outside BodyPotential Benefits
Accelerates and supports the body's natural wound repair processes. This includes reducing inflammation, promoting collagen synthesis, increasing cell proliferation, and facilitating angiogenesis, leading to faster wound closure, reduced scarring, and decreased infection risk.
Reduces inflammation throughout the body, addressing the root cause of many diseases. Modulates inflammatory pathways and promotes tissue healing.
Antioxidant protection defends the body against free radical damage, reducing the risk of chronic diseases and promoting overall cellular health. This is achieved by neutralizing unstable molecules that cause oxidative stress and cellular damage.
Ectoin offers protection against UV-induced skin damage by reducing sunburn cell formation and supporting DNA repair. It's not a replacement for sunscreen but provides additional protection.
EGCG reduces acne breakouts by leveraging its antibacterial and anti-inflammatory properties, regulating sebum production, and modulating the androgen receptor.
Possible Side Effects
Skin irritation involves symptoms like redness, itching, and rashes due to contact with irritants, allergens, or environmental factors. Severity varies based on the cause, individual sensitivity, and affected area; persistent cases may lead to secondary infections.
Allergic reactions are adverse immune responses to normally harmless substances, ranging from mild skin irritation to severe anaphylaxis. Symptoms can include skin issues, swelling, breathing difficulties, and anaphylaxis requires immediate epinephrine injection.
