The fingertips often do housework or contact with irritating things, such as detergent, hand sanitizer, etc., or the amount of washing used at one time is too large, which damages the skin on the fingers, and the skin around the fingertips is dry and dehydrated, which separates the stratum corneum on the surface of the skin and the subcutaneous tissues, which in turn causes the fingertip barbs. 2. Poor nutrition leads to finger skin metabolism problems, the body lacks certain trace elements or vitamins, diet is not uniform, there is not enough nutrients to care for the skin, which leads to the formation of fingertip barbs. 3.
