A slight change in your diet can help make a huge difference. You should include milk, fruits, leafy vegetables, dry fruits, and nuts in your diet. Eat a lot of oranges, watermelons, spinach, carrots, etc. These foods contain vitamins that help keep your skin healthy and supple. Including salmon, tuna, etc. in your diet is also a good idea. They contain omega 3 fatty acids that help in retaining the lipid layer of skin. Avoid drinking more than 2 cups of coffee a day. It acts as a diuretic that sucks the moisture out of your skin.
