The old Indonesian tradition of using caffeine in skin care has been rediscovered by a new generation, making it a favourite ingredient for skin care manufacturers. It has three main skin loving properties; it is an antioxidant, it shrinks blood vessels and it dehydrates fat cells. In eye creams, it shrinks the blood vessels that cause under eye darkness and puffiness.
It is also a popular product in skin tightening and cellulite fighting products. Caffeine can dehydrate the skin, so applying it to fatty areas rich in excess liquids will draw out the excess moisture, improving the appearance and size of uneven skin.
