The Exact Routine This Dermatologist Uses to Fight Her Psoriasis

To protect against UV as well as infrared and visible light rays, I boost my SPF-moisturizer combo (of at least SPF 30) with a few drops of an antioxidant serum. I mix it together in my palm before applying it to my face, neck, chest, and the tops of my hands.
