Acne around the nail is usually not due to a vitamin deficiency, but to the peeling and breaking of the cuticle due to external factors. The rumor that this is due to a vitamin B deficiency is not accurate. The root cause of this condition is that the skin around the nail has no sebaceous glands or hair follicles. When the skin around the nail is too dry and loses its elasticity due to lack of hand care, the broken epidermis will rise from the nail root or edge and form a barb. This problem is more likely to occur for people who have direct contact with skin irritants such as detergents and laundry detergents, and for people who often need to wash their hands. Sometimes it can also occur in children who pick or chew their nails. If the nail around the barb, do not pull out, it is easy to cause pain and bleeding, and if the wound is not properly cared for later, it is also easy to secondary infection. You can soak your hands in warm water or apply hand cream to the barb to soften the cuticle, then cut the barb off with nail clippers and apply skin care products containing vitamin E to promote cuticle repair. To avoid acne, you should pay attention to protecting the skin of your hands and dry them in time after washing your hands to reduce the evaporation of water that takes away the skin’s own moisture. Apply hand cream in time after cleaning to moisturize the skin of your hands, especially the nail edges to focus on the application, not to be ignored. In addition, it is recommended to reduce the frequency of direct contact with irritating cleaning solutions, when using gloves can be worn to avoid irritating the skin. It is also important to avoid removing dead skin by picking your hands on a daily basis to prevent causing the cuticle to break off and form barbs.
