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

1. Drink at least eight 8-ounce glasses of water a day to stay hydrated. This helps flush toxins through your kidneys instead of your skin.

Take these steps for a healthy complexion.

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.

3. Protect your skin from the sun all year round with a sunblock 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.

如果你只想要做三件事就能改善你的皮肤，令其无论是看上去还是感觉上都更好就做以下这三件事吧，它们是被专家所认证的

1. 每天喝至少8盎司水以保持肌肤的水分，这样也有助于排出肾里面的毒素。

采用这些方法来保持健康肌肤。

2. 安排健康的饮食：以水果，蔬菜，鱼类为主食。澳大利亚monash大学的学者为了证明日常的饮食与皱纹的多少之间的联系，研究了453名来自与澳大利亚，希腊和瑞典，70岁以上的老人的食谱。研究发现，日常饮食中，以水果、蔬菜、鱼类为主食的人的皱纹最少。相反，经常食用含有高脂的食物，例如肉类，黄油，全脂牛奶,软饮，蛋糕，甜点，土豆等会加速皮肤的皱纹的生长。

3. 常年使用防晒系数超过三十的防晒霜来保护皮肤。“并不是说下雪天你的皮肤就不会受到阳光的刺激”，Andrea Lynn Cambio, M.D，这位来自纽约的皮肤病专家说。户外的时光的确很美好，但应使你的皮肤远离阳光，或者使用防晒产品。特别说明的是，上午11点到下午3点之间太阳光对皮肤的刺激是最大的。
