Abstract
Abstract A method of and composition for preventing erythema of the skin caused by the absorption of burning ultraviolet radiation resulting from exposure to natural or artificial sources thereof while concomitantly allowing tanning of the skin is provided, consisting of the application of a sunscreen composition demonstrating selective ultraviolet radiation absorption in the 295-315 nanometer wavelength range prior to exposure of the skin to said radiation source, said composition comprising a sunscreen-effective amount of an ultraviolet-absorbing tocopherol compound selected from the group consisting of alpha tocopherol, beta tocopherol, gamma tocopherol, delta tocopherol, epsilon tocopherol, zeta tocopherol, eta tocopherol and mixtures thereof, and an inert carrier vehicle, said vehicle being non-toxic and non-irritating to the skin.
