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 is pigmentation?
Pigmentation refers to any change in the colour of the skin caused by melanin. Hyperpigmentation – the common form – means patches darker than your natural tone, including sun spots, melasma, freckles and the marks left behind after acne or injury.
Melanin is produced by melanocytes in the lower epidermis and handed to surrounding skin cells. When that process is over-stimulated or unevenly distributed, the result is a visible patch rather than an even tone.
What causes pigmentation?
Ultraviolet exposure is the single largest trigger, because UV directly activates melanin production as a protective response. Inflammation is the second: acne, eczema, friction, waxing, burns or harsh procedures can all leave post-inflammatory hyperpigmentation, which is more common and longer-lasting in deeper skin tones.
Hormonal change, certain medications, heat and genetics complete the picture. Without daily sun protection, treated pigment reliably returns.
What ingredients are best for pigmentation?
The most effective topicals work at different points of melanin production: vitamin C and niacinamide, azelaic acid, tranexamic acid, alpha arbutin, kojic acid and liquorice root extract.
Retinoids and gentle AHAs speed up turnover so pigmented cells clear faster. But broad-spectrum SPF worn daily is the ingredient that decides whether any of it holds – without it, results reverse within weeks. Take our Skin Quiz.
