What is coffee in skincare?
Coffee reaches skincare in two forms: ground coffee beans used as a physical exfoliant, and caffeine or green coffee extract used as an active. The two work quite differently.
The grounds provide abrasion; the active fraction provides antioxidant and vasoconstrictive effects. Coffee is also rich in chlorogenic acid, a polyphenol with anti-inflammatory and free-radical scavenging activity.
What skin concerns does coffee treat?
As an active, caffeine reduces puffiness and the appearance of under-eye darkness by constricting small blood vessels, and it is used in body products to temporarily smooth cellulite. Its antioxidants help defend against photo-damage.
As a scrub, ground coffee lifts dead cells and improves texture on the body. On the face the particles are too coarse and irregular for most people – they create micro-tears that inflame skin and worsen the texture they were meant to fix.
What ingredients are best paired with coffee?
For the eye area, pair caffeine with peptides, niacinamide and hyaluronic acid – dehydrated under-eyes look darker no matter what the circulation is doing.
For body scrubs, coffee grounds are usually blended with sugar and an oil such as coconut or almond to soften the abrasion. On the face, use a chemical exfoliant – lactic or salicylic acid – instead. 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.
