Cosmetic compositions containing a micronized metal oxide along with a 4-substituted resorcinol
derivatives of the general formula I exhibit improved storage stability: (I) where each R1 and R2,
independently, represents a hydrogen atom, -CO-R (acyl group), -COO-R, CONHR; where R
represents saturated or unsaturated, linear, branched or cyclic C1 - C18 hydrocarbon groups; and
