ABSTRACT:
The present invention relates to sunscreen compositions having improved photostability, especially in the UVA region, along with providing broad coverage in both the UVA and UVB regions. These compositions are achieved by combining a UVA-absorbing dibenzoylmethane sunscreen with a UVB-absorbing benzylidene camphor sunscreen. In highly preferred embodiments, these compositions also contain from about 0.1% to about 25% of an inorganic physical sunblock. These compositions are useful for protecting the skin from the harmful effects of ultraviolet radiation and for moisturizing the skin.
