Like all things related to acne, alcohol will affect different people in a different ways. Some people may breakout in pimples after every drink whilst others will be able to drink as much as they wish without any noticeable effect.
While there is very little evidence to show that drinking alcohol causes acne there are some definite connections.
1. Drinking regularly will depress your immune system and it is your immune system which helps keep the acne bacteria under control .A weakened immune system will make it easier for bacteria to build up in your skin pores.
2. Alcohol will change your hormone levels and one direct cause of acne is an imbalance in testosterone or estrogen levels.
3. People often drink to help deal with stress, stress is also likely to affect your hormones so the combination of two could lead to problems and have an adverse effect on your skin.
4. It is a well-known fact that alcohol leads to liver damage. The liver is probably the most important organ involved in maintaining clear skin. It regulates a number of hormones, helps maintain steady blood sugar levels and also removes toxins from your body. Anything that reduces liver functionality is likely to be bad for your skin.
5. Alcohol can cause candida to overgrow. Candida is a fungus that is found in high yeast and sugary products (beer, cocktails and mixed drinks). When it overgrows it can result in outbreaks on the skin, whilst it isn't strictly speaking acne it looks very similar.
6. Alcohol lowers your body's water content and water is central to removing inflammatory toxins. These inflammatory toxins can result in aggravated acne. Alcohol will also shrink skin pores and make them more likely to clog.
While alcohol may aggravate your acne it doesn't mean that you should avoid drinking altogether. Drinking alcohol in moderation is unlikely to have any noticeable effect on your skin, but as mentioned it will vary from person to person.
