Abstract
The present invention relates to a composition, especially a cosmetic composition, particularly a photoprotective composition, comprising at least: —photonic particles having an average size comprised from 0.5 μm to 100 μm and each including an arrangement that diffracts monodisperse nanoparticles or voids, the diffraction spectrum of this arrangement including a reflection peak of the first order in the range of wavelengths ranging from 250 nm to 1800 nm, preferably from 250 nm to 400 nm, —at least one absorber, said absorber being a molecule having an absorption spectrum in the UV-near IR domain (100 nm-3000 nm) whose mass extinction coefficient ε1% is greater than or equal to 160 g·100 mL·cm, and —at least one surfactant.
