Abstract
A keratotic plug remover composition comprising a polymer compound having a salt forming group is disclosed. The composition according to the invention can effectively remove keratotic plugs in the skin pores, so that the conspicuousness of the skin pores is mitigated and clean and healthy skin pores can be maintained. The composition does not hurt the skin.
