Deep cracks around the fingernails usually occur as a result of frequent exposure to soap and water, including hand-washing, bathing, cleaning house or doing dishes. Additionally, gardening without gloves, as well as exposure to wind and sunlight, are often the culprits. To treat severe cracks and prevent infection, seal the wounded areas with liquid bandage until they heal, as liquid bandage products help the cracks heal from the inside. Once the cracks are closed -- which usually takes five to 10 days -- daily care will keep the skin around your fingernails supple and pain-free. Consult your physician if the cracks around your fingernail if the cracks are red, painful or leaking pus, because they may be infected. You should also consult a physician if the cracks don't heal up within two weeks. And when you do use liquid bandage, read the packaging carefully to ensure you're following that product's specific directions.
Wash your hands thoroughly with hand soap and water, then dry them gently with a soft towel or allow them to air-dry. Be sure the cracked areas are completely dry.
Apply a small amount of over-the-counter liquid bandage on top of -- but not inside -- the cracks. Apply a second coat after the first coat dries, which takes about a minute. Be sure the crack is completely covered.
Keep the cracks covered with liquid bandage until they are completely healed. Reapply the product as often as needed during that time because the plastic naturally falls off as the wound heals.
Keep your skin well-moisturized to prevent new splits when the cracked areas heal. Use a heavy cream every time your skin is exposed to water. Massage the cream into your fingernails, with extra attention to split-prone areas such as the sides of your nails and under your nails.
Wear cotton-lined rubber gloves whenever you wash dishes or work with household cleansers. Similarly, wear appropriate gloves when working outdoors or in the garden.
