Diet and Your Skin

The skin is the largest organ of the body, and is often a telling sign of what’s going on inside the body itself.

Cosmetic Doctor are often asked by patients about how what they eat impacts the way the skin appears, so here is a quick overview of some key nutritional elements and their significance.

  • Reduce damage caused by free radicals (smoke, pollution).
