Hand barbs, which are caused by too dry skin and cracks in the cuticle, are a manifestation of chapped finger skin, which can easily appear when subcutaneous sweat gland secretion decreases, frequent friction, skin loss of moisture and dryness, and skin keratin thickening and loss of elasticity. Children are prone to hand barbs due to small hands that are easily dirty, unclean to clean, partial and picky eaters, etc. If it still does not heal for a long time, then it may be a lack of vitamin B6 or vitamin C, zinc, iron and other elements. They should be supplemented appropriately. Barbs usually grow next to the nail. Because the barb is attached to the subcutaneous tissue, when you tear the barb with your hand or other tools, it is not only painful, but also injures the surrounding skin and can even cause bleeding and lead to hand infection. So when you have a barb on your hand, don’t keep rushing to pull it out. The correct way is to soak your hand with warm water to make the skin soft and then cut it off with small scissors. Or massage around the nails and knuckles with a nutritional oil containing vitamin E to remove the barbs and soften the rough skin. Then apply a hand cream or glycerin to the affected area. Occasionally a small amount of hand barbs need not be a cause for concern and can be removed carefully. If they occur repeatedly and for a long period of time, they may be a result of poor diet and nutrition and require symptomatic treatment.
