Detailed answer

Caffeine has vasoconstrictive properties, which means it can help constrict blood vessels and reduce inflammation. This can temporarily reduce the appearance of dark circles and under-eye bags. Additionally, caffeine's antioxidant properties can help protect the skin from free radicals, which may contribute to the aging process. However, it is important to note that individual results may vary, and using caffeine-based products alone may not completely eliminate dark circles or under-eye bags. Other factors like sleep, hydration, and genetics can also play a role in their appearance. It is recommended to combine caffeine-based products with a consistent skincare routine and lifestyle habits to achieve the best results.
