Alcohol - That one glass of wine at dinner may not seem to affect you, but avoid drinking more than that. Like caffeine, alcohol dehydrates the body and makes it difficult for skin to maintain sufficient levels of hydration. In addition, alcohol causes blood vessels in the skin to dilate, creating a feeling of warmth that can aggravate a variety of skin conditions such as rosacea, psoriasis and acne.

Sugars - Today, many doctors believe that sugar can cause wrinkles. How? Some researchers claim that excess sugar reacts with proteins in the skin, resulting in a breakdown of collagen. This triggers wrinkles since collagen is responsible for keeping our skin firm and elastic. While some doctors emphasize that this research is inconclusive, staying away from sugar and processed foods won't hurt. Stick with fruits, whole-grain breads and pastas. You can lower the possibility of sugar-induced wrinkles and keep your waistline and teeth happy.
