Coffee & Caffeine
We drink a coffee to wake up in the morning, we share a coffee with friends or we enjoy a coffee at the balcony with a good book… Espresso, filtered, boiled or instant, coffee is always delicious and rich in caffeine. But what does caffeine have to do with skin care?
Why is Caffeine so widely used in cosmetics?
Caffeine is a natural and biologically active compound. We often find it in our cosmetics and that happens for a series of reasons:
- Caffeine stimulates the metabolism, prevents the accumulation of excess of fat in the cells but also stimulates the breakdown of existing fat and that’s why caffeine a great anti-cellulite ingredient.
- When combined with Centella Asiatica polyphenols, it prevents fat storage, protects the skin from oxidation and maintains its elasticity.
- When combined with ivy extract, it decongests and detoxifies adipose tissue, while preventing the recurrence of cellulite and localized fat.
- Caffeine increases the microcirculation of the blood in the skin, helping to remove toxins from the body.
- Caffeine also has strong antioxidant properties, as it protects cells from ultraviolet radiation and slows down the skin’s aging process. Thus, its usage in sunscreen products,
promotes skin protection from the formation of free radicals and photoaging caused by the sun’s UV radiation.
- Caffeine slows down hair loss and stimulates hair growth.
- Caffeine effectively reduces the swelling of the tissue under the eyes.
- And the highlight is left for the end; Caffeine due to its low molecular weight penetrates the skin barrier and it is easily absorbed by the skin. In fact, its penetration is greater when it is formulated in emulsions, such as creams, compared to aqueous solutions, such as serums.
Caffeine’s multifunctional and holistic properties, along with its natural origin, turned it in one of our favorite ingredients, found in many of our products:
