The Simple Diet Hack Dermatologists Swear By For Younger-Looking Skin

"The most important ingredients in a proper skin diet are high-quality proteins, minerals like zinc and selenium that are essential for skin renewal, and antioxidants that help protect the skin from damaging free radicals," Dr. Harth explained.

And fish, particularly coldwater fish, is an excellent source of just about every nutrient our skin craves.

Dr. Harth continued, "The best source of high-quality protein is cold-water fish. Fish, such as salmon, mackerel, and herring, are excellent foods for healthy skin. In addition to proteins that are the budding blocks of our skin, they are rich in omega-3 fatty acids and vitamin E, proven to be powerful antioxidants and anti-inflammatory agents which help reduce redness associated with acne-prone skin and rosacea.

"Coldwater fish are also a good source of Zinc. Zinc is a mineral that is essential for vital for the production of new cells in the skin and hair follicles. Its deficiency can lead to fragile skin and delayed wound healing.

Don't care much for fish? That isn't much of a problem, because Dr. Harth told us that there are a few other types of foods that can provide similar benefits. These include leafy green vegetables like broccoli, spinach, and kale, yellow and orange vegetables, nuts and seeds, as well as and green tea.

He said, "Kale, broccoli, and spinach are full of many vitamins, and minerals essential for skin health, including zinc, vitamin A and vitamin C. These magical veggies also contain lutein, a compound that works like beta-carotene protects your skin from oxidative damage and premature skin aging."
