The very dry skin on the feet is mainly caused by too little moisturizing factors such as water content in the stratum corneum, or by a large loss of water due to a small break in the skin surface. Treatment requires moisturizing and water locking treatment. Chinese herbal medicines such as licorice oil or comfrey oil can be applied to clear heat and detoxify and cool the blood and moisturize the skin, or petroleum jelly or glycerin can be selected for application to quickly lock in water and reduce water loss, along with daily application of moisturizing lotions and moisturizers. If there are small papules with itching, consider the possibility of eczema, and also with oral levocetirizine hydrochloride oral solution and topical dinaide ointment for treatment.
