Babies with barbs are usually referred to as hands, small pieces of epidermis on the sides and lower ends of the nails that have buckled due to dryness and cracking. There is a relationship between babies’ barbs and dry skin, abrasion and vitamin C deficiency. 1. Dry skin: Excessive dryness of the skin can lead to localized dryness and cracking of the skin, which may then lead to the appearance of barbs. 2. Wear and tear: Children’s skin is delicate and frequent friction with other objects may also irritate the skin and lead to the appearance of barbs. 3. Vitamin C deficiency: Vitamin C is an essential nutrient that helps in tissue repair. When vitamin C is severely deficient, the local skin breaks down and does not heal for a long time. Baby hands long barbs should take the child to the hospital pediatrics or dermatology to see, and under the guidance of the doctor to take reasonable measures to deal with. Usually must pay attention to the cleanliness and protection of the child’s hands.
