Could you please assist with information on whether drinking four cups of coffee daily is harmful for the skin, and if it is, what would be the effect on the skin.

Hi M, thank you for the question.
I will presume by coffee you mean specifically its ‘kick-start’ ingredient caffeine. The effects of caffeine on the body has been studied extensively and basically it acts as a central nervous system stimulant warding off drowsiness and increasing alertness (temporarily) and it increases metabolism. Please remember that other beverages contain caffeine, such as tea, soft drinks and energy drinks. Furthermore the total caffeine found in a ‘cup of coffee’ varies and this should be taken into consideration together with any other source of caffeine. The effect of caffeine can be lengthened with the use of oral contraceptives and during pregnancy.
The main side effect on the skin seems to be an indirect one which will include the diuretic effect that may result in a slight dehydration of the body and the skin itself, as well as the effect on the skin resulting from the release of the stress hormones. So as ussuall 'everything in moderation'.
