Disclosed is a drug for blocking light having a wavelength in the range of 370 to 500 nm for inhibiting degradation of endogenous carotenoids present in the skin, and a skin external preparation containing the same. Flavonoid polyphenols, carotenoids, chlorophylls, melanins, specific aminoarylvinyl-s-triazine compounds, specifically 2,4,6-tris (2-ethylhexyl-4'-ylamino-) α-cyanocinnamate) -s-triamine or the like is used as a shielding agent. [Effect] 370-500 nm light (corresponding to blue light) is shielded, the accumulation of carotenoids inherent in the skin can be maintained, and the natural skin color can be maintained.
