FAQ

1. Can caffeine reduce puffiness?

Yes, caffeine is effective at reducing puffiness, especially around the eyes. This is one of the main caffeine benefits for skin. Caffeine works as a vasoconstrictor: it narrows blood vessels. This reduces blood flow and stops fluid from building up in the tissues, which reduces puffiness. Keep in mind that this effect is temporary.

2. How long does it take to see results from caffeine skincare?

Results depend on the specific product, as well as how caffeine and skin interact individually. Some caffeine products give quick results, making the skin around the eyes look more lifted and refreshed right away, since caffeine narrows blood vessels. But for longer-lasting results (like fading dark circles and improving skin texture) you'll need to use the product regularly.

3. In which skincare products is caffeine most commonly found?

Caffeine is a popular ingredient found in many skincare products. It's most common in eye care products, face serums, and toners.
