We were discussing alcohols effect on the skin over at the antiaging section and peri was nice enough to post an article about it. Well according to the article "alcohol interferes with the body’s processing of vitamin A (including retinoids). According to Stryker et. al, the consumption of alcohol leads to a reduced absorption of vitamin A from the diet. Because vitamin A is a known antioxidant with anti-aging properties, decreasing its absorption may lead to advanced aging. In addition, retinoids may not be as effective following excessive alcohol consumption, as Leo and Lieber note there is competition between ethanol and retinoic acid precursors, leading to accelerated breakdown of retinol through the cross-induction of degradative enzymes. With retinoids available for less time in the system, it is highly probable less efficacy is achieved, and more probable that the retinoids produce toxic by-products. The latter was verified by Leo and Lieber, as ethanol promotes the toxicity of both vitamin A and ß-carotene in the body. The researchers thereby caution that discretionary (reduced) amounts of vitamin A and ß-carotene are used by drinking populations to decrease the risk of toxicity in the body".
