摘要：
The present invention can provide cosmetic formulations comprising hydrochalcone compounds of the general formula (I):
in which
R 1 to R 4 are each independently H or -COR, and R is an alkyl group having 1-20 carbon atoms
as effective components, which are highly effective in suppressing pigment deposition and depigmenting the skin and which are very safe to the skin and highly stable during storage.
