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 are fine lines?
Fine lines are the earliest visible sign of skin ageing: shallow creases that appear where skin is thinnest and most expressive – around the eyes, across the forehead, and at the corners of the mouth.
They differ from established wrinkles in that they are often still dynamic, showing mainly when you smile or squint, and are frequently worsened by dehydration. That makes them the most responsive stage to treat.
What causes fine lines?
Intrinsic ageing does part of the work: collagen production falls by roughly one per cent a year from the mid-twenties, elastin degrades, and the dermal matrix thins so skin no longer springs back.
The larger share is external. Ultraviolet exposure accounts for the majority of visible facial ageing, and pollution, smoking, poor sleep, sugar-driven glycation and repeated facial movement all accelerate it. Dehydration makes existing lines look deeper than they are.
What ingredients are best for fine lines?
Retinol and prescription retinoids have the strongest evidence for stimulating collagen and smoothing texture. Vitamin C protects against free-radical damage while supporting collagen synthesis, and peptides signal the skin to rebuild.
Pair those with hyaluronic acid and ceramides for immediate plumping and barrier support, niacinamide for tone, gentle AHAs for surface renewal, and coenzyme Q10 as an antioxidant. Daily broad-spectrum SPF protects everything else you are doing. Take our Skin Quiz.
