If you do only three things to improve the look and feel of your skin, make them these three, agree several of our experts:

如果只要做三件事就能改善皮肤质量，令其无论是看上去还是摸起来都更棒，那么就做以下这三件事吧，它们可是经过专家认证的。

1. Drink at least 8-ounce glasses of water a day to stay hydrated. This helps flush toxins through your kidneys. Take these steps for a healthy complexion.

每天喝至少8盎司的水以保持肌肤的水分，这样也有助于排出肾里面的毒素，让你拥有健康的肤色。

2. Follow a healthy diet rich in fruits, vegetables, and fish. When researchers from Monash University in Australia studied the diets of 453 people ages 70 and older from Australia, Greece, and Sweden to see if there was any correlation between what they ate and the number of wrinkles in their skin, they found those who ate the most fruits, vegetables, and fish had the fewest wrinkles. Conversely, the researchers found, foods high in saturated fat, including meat, butter, and full-fat dairy, as well as soft drinks, cakes, pastries, and potatoes, increased the likelihood of skin wrinkling.

安排健康的饮食，多吃水果，蔬菜和鱼。澳大利亚莫那什大学的研究者为了证明日常饮食与皱纹多少之间的联系，研究了453名来自澳大利亚、希腊和瑞典的70岁以上的老人的食谱。研究发现，日常饮食中，以水果、蔬菜、鱼类为主的人的皱纹最少。相反，经常食用含有高脂的食物，如肉类、黄油、全脂牛奶、软饮、蛋糕、甜点、土豆等会加速皮肤皱纹的生长。

3. Protect your skin from the sun all year round with a sun block with an SPF of 30 or greater. Just because there's snow on the ground doesn't mean your skin can't be damaged by the sun, says Andrea Lynn Cambio, M.D., a New York City dermatologist. Time outdoors is time well spent, but be sure to keep your skin either well covered or well protected with sunblock. In particular, the sun is at its most damaging between 11 a.m. and 3 p.m.

常年使用SPF30或防晒系数更高的防晒霜来保护皮肤。来自纽约的皮肤病专家安德里亚·林恩·卡姆比奥,M.D表示，并不是说下雪天你的皮肤就不会受到阳光的刺激。户外时光的确很美好，但应确保你的皮肤远离阳光或者得到防晒产品的保护。特别需要注意，上午11点到下午3点之间的阳光对皮肤的刺激是最大的。
