摘要：
In one aspect, a cosmetic composition includes a sunless tanning agent and a sunscreen agent. A photostabilizer is added to stabilize the sunscreen agent from the destabilizing effect of the sunless tanning agent. In this manner, UV protection is provided to the user when the cosmetic composition is applied to skin. In another aspect, a water-based sunless tanning/sunscreen composition includes a sunless tanning agent, a sunscreen agent, and a photostabilizer. The sunless tanning agent is DHA, and the sunscreen is avobenzone. Because the avobenzone degrades when exposed to UV radiation when used with DHA, the photostabilizer is added to enable the avobenzone to retain most of its original ability to absorb the UV radiation. The photostabilizer is a low molecular weight copolymer of adipic acid and neopentyl glycol.
