The invention relates to novel UVB/UVA-absorbing chromophores that are present in the natural products of a marine hydroid, and derivatives thereof, useful as sunscreening agents. Furthermore, the present invention relates to methods for protecting skin from the damaging effects of solar ultraviolet radiation. This method comprises topically applying to the skin an effective coating of a sunscreen composition of the present invention. Additional embodiments of the invention use these natural UV-absorbing compounds, or derivative thereof, as additives as a means of providing UV-protective plastics, paints, and waxes.
