Abstract

Cyclopamine or a similarly specific inhibitor of Hedgehog/Smoothened (Hh/Smo) signaling can be used for obtaining decrease of pigmentation of hyperpigmented skin areas.

Claims

1. A method for causing decrease of pigmentation in hyperpigmented skin areas, comprising

administration of cyclopamine or another compound that specifically inhibits Hedgehog/Smoothened signaling,

wherein said administration is in a dosage that provides decrease of pigmentation in said skin areas.

2. A method according to claim 1, wherein cyclopamine or said compound is applied in a cosmetic formulation.
