## Abstract

The present invention provides a photo-protective composition that has a synergistic combination of at least one sunscreen agent and at least one carotenoid, which results in a composition with an increased SPF compared to a composition without the synergistic combination. Preferably, the composition also has at least one of the following additional components: emulsifier, emollient, skin-feel additive, moisturizing agent, film former/waterproofing agent, pH adjuster/chelating agent, preservative, or any combinations thereof.
