Facial sunscreens have different compositions than sunscreens for the whole body. A facial sunscreen should be easier for the skin to absorb and feels lighter. You’re also less likely to break out in acne with facial sunscreen than with standard sunscreen. That said, if you don’t have facial sunscreen on hand, regular sunscreen will do fine. It will still protect your face from the sun’s rays. You just may find it feels slightly uncomfortable after you apply it.
