Self-tanner gives your skin a temporary tan by coloring the outermost layer with the help of active ingredients like Dihydroxyacetone (DHA) and Erythrulose. However, self-tanner does not provide any protection against the sun’s harmful UV rays. It is not a sunscreen and does not act as a physical barrier to prevent sun damage. If you plan to spend time in the sun after applying self-tanner, we recommend waiting at least two hours and then applying a broad-spectrum sunscreen with SPF. Combining self-tanner with sunscreen is the best way to enjoy a beautiful glow while keeping your skin safe and healthy.
