About Caffeine
Topical caffeine is a synthetic ingredient used in cosmetic and personal care products. It's purported benefits include reducing the appearance of cellulite and dark circles, and skin firming, primarily due to its vasoconstrictive and dehydrating effects. Limited evidence suggests potential hair growth stimulation. However, users should be aware of potential side effects such as skin irritation and allergic reactions. Dosage should always follow product instructions.
