Use of carboxylic acid to stabilize or improve epidermal synthesized ceramide

摘要

The invention relates to the use of carbonic acid or CO2 for producing a pharmaceutical or cosmetic preparation for topical application for stabilizing or increasing the epidermal ceramide synthesis rate. This improves the epidermal permeability barrier and reduces the transepidermal water loss. The preparation is additionally suitable for preventing or treating atopic dermatitis (neurodermatitis).
