2. Don't smoke 不要吸烟
Smoking makes your skin look older and contributes to wrinkles. Smoking narrows the tiny blood vessels in the outermost layers of skin, which decreases blood flow. This depletes the skin of oxygen and nutrients, such as vitamin A, that are important to skin health. Smoking also damages collagen and elastin — fibers that give your skin its strength and elasticity. In addition, the repetitive facial expressions you make when smoking — such as pursing your lips when inhaling and squinting your eyes to keep out smoke — may contribute to wrinkles.
吸烟会加速你的皮肤衰老并且增加皱纹。吸烟将使皮肤最表层的毛细血管变窄，这将使血液流动变慢。那么皮肤中的氧含量和养分将会下降，例如维他命A，它对皮肤健康起重要作用。吸烟也会破坏胶原蛋白和弹性蛋白——纤维细胞，它将使你的皮肤韧性和弹性。另外，吸烟时重复的脸部表情——例如吸入时候要撅起嘴唇并瞥着眼睛不让烟进入眼睛——也会增加皱纹。
If you smoke, the best way to protect your skin is to quit. Ask your doctor for tips or treatments to help you stop smoking.
