Scientific research has shown that caffeine can help cells combat the harmful effects of UV radiation and photoageing, thus helping to delay wrinkles, sun spots and loss of elasticity. It also has a local action with no systemic effect, acting on fatty tissue lipolysis by inhibiting phosphodiesterase.
In cosmetics, caffeine helps to contract small blood vessels and minimise inflammation, thus reducing dark circles and eye bags. Furthermore, its antioxidant properties also neutralise oxygen free radicals.
