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 clogged pores?
A clogged pore is a hair follicle blocked by a mix of sebum, dead skin cells and debris. Left open to the air the plug oxidises and darkens into a blackhead; sealed over by skin it becomes a whitehead or closed comedone.
Clogged pores are the starting point of nearly all acne – the microcomedone forms first, and inflammation follows only if bacteria and immune response get involved.
What causes clogged pores?
Excess sebum and abnormal keratinisation are the two mechanics. When the follicle lining sheds cells faster than they can clear, they bind with oil and form a plug.
Comedogenic products (heavy oils, some silicones and waxes), thick makeup worn for long stretches, humidity, sweat left on the skin, hormonal shifts and insufficient cleansing all contribute. So does over-cleansing, which damages the barrier and drives oil production up.
What ingredients are best for clogged pores?
Salicylic acid is the first choice because it is oil-soluble and works inside the pore rather than just on the surface. Glycolic and lactic acid clear the surface layer, and clay masks absorb excess oil weekly.
Retinoids are the most effective long-term fix, because they change how the follicle sheds in the first place. Add niacinamide to regulate sebum and keep the barrier intact, and switch to non-comedogenic, lightweight hydrators. Take our Skin Quiz to find products that will not re-clog you.
