Know what to eat

Take 160 mg of soy isoflavones per day or pour soy milk over your cereal. Soy consumption may keep glowing skin healthy by supplying high-quality protein needed for building and maintaining collagen, the material essential to connective tissues, says medical research director, Dr Aaron Tabor. Soy isoflavones may also act as antioxidants to protect collagen from damage caused by free radicals, highly reactive molecules that can weaken or destroy cell membranes. Free radicals can also damage DNA, create age spots and wrinkles, and depress the immune system, increasing the risk of skin cancer. Good sources of soy isoflavones include soy milk (20-35 mg soy isoflavones per serving) and tofu (20-30 mg soy isoflavones per serving).
Grill salmon brushed with olive oil and sprinkled with toasted, crushed walnuts

There, you’ve just gotten a skin-healthy dose of poly- and monounsaturated fats, particularly omega-3 fatty acids, which studies suggest may affect the amount of sun and ageing damage your skin experiences. Without them, you’ll also show the signs you aren’t eating enough healthy fats, such as dry skin. By extension, make sure olive oil is the primary source of fat in your cooking each and every day, and try to have salmon twice a week or more to support glowing skin.

Cook with garlic every day

Because garlic contains antibacterial properties, it may help clear up P. acnes, or the acne-causing bacteria that lurks on your skin. Avoid rubbing the garlic directly onto your acne, as dermatologist, Dr Jeremy A. Brauer, warns that it may result in an irritant or allergic contact dermatitis.
