Caffeine is an ingredient most people probably associate most readily with drinks like coffee and tea, but it shows up in many other beverages and foods as well, which may not be as obvious. Soda, chocolate and pain killer medications may also contain significant quantities of caffeine. Caffeine can stimulate the release of hormones which can lead to acne breakouts. Caffeine can also disturb your sleep which reduces your body’s natural ability to detoxify itself, which may further increase your risk of skin problems.
