Caffeine is one of the most sought out key ingredients in skin care products. It protects the skin from damage induced by free radicals. They are molecules that break down collagen causing fine lines, wrinkles, or other signs of ageing like saggy skin. Additionally, caffeine's anti-inflammatory properties help ease redness and alleviate skin harm due to sun exposure.
Caffeine acts as a vasoconstrictor. It makes the blood vessels tight and reduces blood flow making skin appear bright and smooth. Caffeine-based products also help minimise the appearance of dark circles or under eye bags caused by sleeplessness or general tiredness.
