Supplements are a big business, but the manufacturers are not regulated by the FDA. Unless you’ve been guided by a physician to take a vitamin due a deficiency, think twice about supplements.
Diet is the best way to get nutrients. The health of your skin, and even the aging of your skin, is affected by what you eat. Eating a lot of sugary foods on a regular basis can make your skin look older. High-temperature cooking also causes excess glucose in skin fibers and affects your collagen’s ability to repair itself.
Improve your diet with more vegetables, fruits, fish and olive oil. Avoid processed foods and those that are grilled, fried and roasted. Your skin will thank you.
