What is green tea in skincare?
Green tea extract comes from the unfermented leaves of Camellia sinensis. Its activity is driven by polyphenols called catechins, the most abundant and most studied of which is epigallocatechin gallate, or EGCG.
On an ingredients list it appears as Camellia sinensis leaf extract. Because the catechins are potent antioxidants and anti-inflammatories, green tea has become one of the best-researched botanical actives in skincare.
What skin concerns does green tea treat?
It calms redness and irritation, making it useful for rosacea-prone, sensitive and post-procedure skin. Its antibacterial and sebum-regulating effects help mild acne and oily skin.
Topical application reduces UV-induced damage and inflammation, which positions green tea as a preventative anti-ageing ingredient alongside sunscreen rather than a replacement for it. It also supports skin under the eyes where puffiness is a concern.
What ingredients are best paired with green tea?
Layer it with other antioxidants – vitamin C, vitamin E, resveratrol, ferulic acid – for broader free-radical coverage in the morning.
For acne it works well with niacinamide and salicylic acid; for sensitivity, with centella asiatica, panthenol and ceramides. It is gentle enough to combine with almost anything, and is a good way to add antioxidant protection to a routine built around retinoids. Take our Skin Quiz.
What is adult acne?
Adult acne is acne that persists past the teenage years or appears for the first time in your twenties, thirties or later. It affects a substantial share of adults, and disproportionately women.
It tends to look different from teenage acne: fewer widespread blackheads, more deep tender lesions along the jawline, chin and neck, often on skin that is simultaneously dry, sensitive or already showing early signs of ageing.
What causes adult acne?
Hormonal fluctuation is the leading driver – menstrual cycles, coming off or starting contraception, pregnancy, perimenopause and conditions such as PCOS all shift androgen activity and sebum output.
Stress and cortisol, sleep debt, high-glycaemic diets, comedogenic makeup and skincare, friction, and certain medications compound it. Adult skin also heals more slowly, so marks linger longer than they did at nineteen.
What ingredients are best for adult acne?
The challenge is treating acne without wrecking a barrier that is also ageing. Retinoids do double duty here, clearing follicles and stimulating collagen at the same time.
Azelaic acid is excellent for adult skin because it handles lesions, redness and post-acne marks together. Add salicylic acid used sparingly, niacinamide to regulate oil and calm inflammation, and ceramides plus hyaluronic acid to keep hydration up. Skip harsh benzoyl peroxide concentrations and scrubs.
