Tea or coffee: What is best for the skin?

In recent times, caffeine has begun to be placed in the target of banned foods, linking with skin aging. Aesthetic gurus, such as the dermatologist of the famous Nicholas Perricone, recommend replacing coffee with green tea. Ricardo Ruiz, dermatologist at the International Dermatological Clinic in Madrid, dismantles it: "there is not a single study that proves that caffeine is bad for the skin. In fact, it has a lot of phenol-type antioxidants, more than green tea. On the other hand, there are studies suggesting that caffeine increases life expectancy in relation to coronary artery disease and stroke. "

Another research by the Instituto Dermopático de la Inmaculada, in Rome, points to the hypothesis (still preliminary) that caffeine can play a very positive role in preventing melanoma.

"Alcohol produces a series of negative effects on the skin. Some are direct, through the redness of the so-called couperosis. Others are indirect, because it prevents the absorption of certain vitamins needed to show healthy skin, "says Ruiz.

Studies of the American Society of Physiology Point both to dehydration — by the diuretic capacity of alcoholic beverages — as well as to the blockage especially of vitamin A — responsible for cell regeneration and collagen production — as the culprits of premature aging. A recent study by Yale University points to the relationship of alcoholism also to vitamin C absorption problems, by how ethanol interferes with the pancreas.
