摘要

A novel drug for treating a vascular lesion in the skin or the subcutaneous soft tissue caused by light irradiation which is efficacious in treating a vascular lesion in the deep part of the skin or the subcutaneous soft tissue caused by light irradiation without destroying normal cells on the skin surface and yet requires only a short shading time after the treatment. This drug for treating a vascular lesion in the skin or the subcutaneous soft tissue caused by light irradiation contains, as the active ingredient, mono-L-aspartyl chlorin e6, mono-L-glutamyl chlorin e6 or a pharmacologically acceptable salt thereof.
