This sunscreen stick was used twice. I just don't find myself reaching for it because I'm partial to creamy/liquid sunscreens. The outside is a little scuffed from bumping against other makeup and skincare items in a makeup bag. It was only ever used on clean, bare skin and has since been sanitized. It has been stored in a cool, dry area of a smoke-free home. ---- A portable sunscreen stick with SPF 50+ and an invisible, hydrating finish that can be re-applied anytime, over or under makeup for all skin types. This convenient, lightweight sunscreen has a protective veil that's strengthened when it senses water and heat. The residue-free formula is infused with naturally-derived skincare ingredients to prevent wrinkles and dark spots. Good for face and body.
