What you need to know about caffeine.

Naturally present in over 60 species of plants worldwide, caffeine is undoubtedly one of the most sought-after ingredients in natural cosmetics. Here is the essential information to know about this ingredient with numerous virtues.

The essentials about caffeine.

Caffeine is an alkaloid from the methylxanthines family. It is particularly found in coffee, which is where it gets its name, but also in tea, guarana, mate, kola nuts, cocoa beans, and so on. In its natural state, it protects plants from insects by killing or paralyzing them.

Naturally derived, caffeine is obtained through supercritical fluid extraction from plants, an alternative to distillation processes. This gentle extraction method allows for the collection of highly concentrated, lipophilic plant substances rich in the plant's active ingredients. These substances are very pure and unaltered, all without the use of petrochemical solvents and leaving no solvent residue.

Here, CO2 has been used as an extraction solvent for caffeine from coffee beans, maté, cocoa, or tea leaves, due to its physicochemical properties (colorless, odorless, non-toxic, non-polluting, non-flammable). In short, once the desired compound is dissolved in the supercritical CO2 environment, we obtain a pure and concentrated extract through depressurization, which then triggers the separation of the CO2, returning it to a gaseous state, and the extract, recovered in liquid or solid form.

What are the benefits of caffeine?

Well-known for its stimulating and energizing effects, caffeine is found in many body and facial care products: toning body products, eye contour treatments, creams against signs of aging or redness, as well as products against hair loss. We detail them for you:

  • Decongesting Effect : By stimulating microcirculation of blood and combating water retention in its capacity as a vascular tonic, caffeine will decongest the sensitive area around the eye, reducing the visibility of bags as well as unsightly dark circles in order to restore radiance to the eye contour.

  • Lipolytic Effect : The application of caffeine induces lipolysis in fat cells (destruction of fats) and inhibits their lipogenesis (production of fatty substances), resulting in a decrease in adipocyte volume and thus an improvement in skin surface. Therefore, caffeine possesses slimming properties due to its lipolytic activity on adipocytes and helps to reduce the appearance of cellulite. However, caffeine alone is not enough. To enhance its action, the practice of a kneading-rolling massage is essential. Indeed, treatments containing the molecule should be accompanied by a vigorous massage.

  • Soothing Effect: The vasoconstriction caused by caffeine also has applications in facial care. The reduction of blood vessels helps to decrease redness and other skin irritations in sensitive or dry skin, for instance in cases of rosacea.

  • Antioxidant Effect: Thanks to its polyphenol content, caffeine also has antioxidant properties. Indeed, it helps to combat free radicals and their harmful effects on the skin, factors responsible for premature skin aging. This property also makes it a good active ingredient to fight against the signs of aging, as it helps to slow down the skin aging process and delay the appearance of wrinkles.

Should we avoid caffeine on certain skin types?

The caffeine is considered a G.R.A.S. (Generally Recognized As Safe - Generally Recognized as Safe) and is deemed safe for use by health authorities. Even though rare cases of hives and allergies have been reported, it is not known to be particularly sensitizing or allergenic and can be used by the most sensitive skin.

Tips to enhance the effect of caffeine on the skin.

To optimize the effectiveness of caffeine-based skincare, it is recommended:

  • Apply it by performing a kneading motion for body products, to promote the lipolytic effect and the breakdown of fats. This type of massage will thus help to smooth out dimples and improve the appearance of cellulite.

  • For facial and eye contour care, it is recommended to gently massage and tap the targeted area, which can have a decongesting effect and stimulate blood and lymphatic microcirculation. This can help reduce puffiness and bags, and minimize the appearance of dark circles.
