The cause and pathogenesis of chicken skin is not yet clear, but may be related to genetics, vitamin A deficiency, and metabolic disorders. It is mainly manifested by the thickening of the skin’s stratum corneum, which leads to clogging of the pores and the formation of a bump, mainly on the outside of the upper arms, lower legs, neck and the entire back. The actual skin is usually not curable, but the symptoms can be relieved by some medical methods, such as medication, laser treatment, etc. 1, medication: patients can use topical preparations such as vitamin A acid, salicylic acid and urea to soften the keratin and improve the symptoms under the guidance of a professional doctor. However, they should not be used for a long time to avoid damaging the skin barrier. In addition, due to the teratogenic effect of retinoic acid, pregnancy and breastfeeding women are prohibited; 2, laser treatment: If the medication does not work, patients can try laser treatment, but it usually takes several courses to take effect. In daily life, chicken skin patients can exfoliate regularly to relieve symptoms, common methods such as using scrubbing particles of body lotion, with a bath sponge, etc.. It is also important to moisturize the skin regularly, such as applying moisturizing oils and body lotions. In addition, patients should avoid scratching or picking at the areas with chicken skin, as this is not conducive to recovery.
