Dry eczema is also called cracked eczema, which is the scientific name for lipid-depleted eczema. It is mainly due to loss of skin moisture, reduced sebum secretion, dryness, fine cracks in the epidermis and stratum corneum, and reddish skin, with more pronounced redness at the cracks, similar to “broken porcelain”. It can occur in many parts of the body, but mostly in the extremities, especially the front of the shin in the elderly. The disease is mostly seen in winter, when the air is dry and secretion is reduced, combined with hot water scalding too often and stimulated. Cause Mainly due to the loss of skin moisture, sebum secretion reduction or poor function. It is seen in patients with ichthyosis or elderly people. Excessive bathing, use of strong alkaline soap, facial cleanser or high bathing water temperature can also cause artificial skin degreasing. Clinical manifestations The disease is mostly seen in winter, and the elderly and those who take bath excessively are prone to it. It is more common on the extensor side of the lower legs and hands. The disease develops slowly due to reduced sebaceous gland function. Itching usually starts around the age of 50 after bathing, and gradually increases with age. Those caused by excessive washing or the use of degreasing agents have a rapid onset and are actually irritant contact dermatitis. The disease is also seen in patients with tumors, those using diuretics or type II histamine blockers, and those with HIV infection. Diagnosis Based on the characteristic clinical manifestations, the diagnosis is not difficult. Treatment First remove the cause. Treat with emollients. For example, white petroleum jelly, vitamin E cream, mineral oil, etc. Available 1 to 2 times a day. Use emollient oils immediately after bathing. To retain the moisture in the skin from evaporating. It is best not to use topical corticosteroid preparations because the skin barrier function has been significantly disrupted.
