Carotene isomers show distinct light responses and skin benefits
Scientists developed a purification method to isolate four geometric isomers of ζ-carotene, a precursor to lycopene. They characterized each isomer's spectral properties, photoisomerization, UV shielding, antioxidant activity, and skin-related biological effects. The results highlight ζ-carotene's potential as a natural skin-protective ingredient.
