Introducing All Fitz by AgeLess Skincare. A tinted, mineral sunscreen made with 20% zinc oxide. It’s vegan, cruelty free, oil free, fragrance free and great for sensitive skin. It will not pill and sits beautifully under makeup. All Fitz is hydrating and contains potent antioxidants, vitamins C and E. The name, All Fitz, refers to the Fitzpatrick Scale. The Fitzpatrick scale is a numerical classification for human skin color. It was developed in 1975 by American dermatologist, Thomas B. Fitzpatrick as a way to estimate the response of different types of skin to ultraviolet light. We called it All Fitz because it fits all skin tones without leaving a white cast.
