Cracked skin heals fastest with gentle cleansing, a thick moisturizer or ointment applied right after washing, and coverage with a bandage or socks when the crack is splitting or on a heel.
For the full breakdown, see our best Cream For Dry Cracked Skin guide.
Dry, cracked skin happens when the outer layer loses enough moisture to split open, typically on hands, heels, or knuckles. The split creates a direct path for bacteria, so the treatment priorities are simple: clean it without making it worse, lock in moisture, and protect the crack from reopening. Most cases resolve in a few days with consistent home care, but knowing which steps actually help — and which common ones don’t — makes the difference between a fast heal and a slow, painful one.
Clean the Crack Without Making It Worse
Wash the area with plain water and, if needed, mild soap around the wound but not inside it. Mayo Clinic’s first-aid guidance advises against hydrogen peroxide or iodine on open cracks because they can irritate the wound and slow healing. Wash your own hands first to cut infection risk, then gently clean the crack. Pat dry with a clean towel — never rub — because friction on already-thin skin can widen the split.
For thick callused heel cracks, the American Academy of Dermatology (AAD) recommends a brief lukewarm soak first: 10 to 20 minutes in plain water softens the dead skin so the moisturizer can penetrate deeper. Hot water is a mistake; it strips the natural oils the skin needs to stay flexible.
Moisturize Immediately — and Use the Right Kind
A plain petrolatum-based ointment like petroleum jelly applied within five minutes of washing is the single most effective home treatment for cracked skin.
The AAD specifies the timing as critical: pat the skin lightly dry after bathing, then apply the moisturizer while the skin is still damp. This traps residual moisture and creates a seal that lets the crack heal from the inside. For hand or finger cracks, a thin layer of petroleum jelly covered with a simple bandage or liquid bandage works. For deep heel cracks, the AAD recommends a thicker layer at night covered with socks — “overnight occlusion” that drives moisture deep into the fissure.
If the skin on the heels is thick and callused, look for a cream containing 10 to 25 percent urea, alpha hydroxy acid, or salicylic acid. These ingredients soften dead, hard skin so the crack can close.
Protect the Crack and Stop the Cycle
Cover any crack that is splitting, bleeding, or located on a heel or fingertip, and change the dressing daily or when it gets wet. A bandage, gauze pad, or liquid bandage keeps dirt out and holds the ointment in place against the wound. Minor surface cracks on the hands that aren’t open can heal uncovered as long as you reapply moisturizer several times a day — especially after hand washing, which the AAD identifies as a moment when skin loses moisture fast.
Prevention is where most people fail: long hot baths, harsh fragranced soaps, and rubbing skin dry undo the repair work. Swap to a gentle fragrance-free cleanser, keep baths under 10 minutes, and wear gloves when washing dishes or cleaning. If winter air is making the problem worse, running a humidifier in the bedroom adds moisture back into the environment and gives the skin a break overnight.
FAQs
How long does cracked skin take to heal?
With consistent cleaning and moisturizing, superficial cracks usually begin closing within two to three days. Deeper heel fissures may take one to two weeks of nightly ointment and sock wear. If there is no improvement after a week, the crack may need medical assessment.
Should I use antibiotic ointment on cracked skin?
Plain petroleum jelly is usually sufficient because it keeps the wound moist and protected. Some antibiotic ointments can cause a rash; if you use one and see redness or itching, stop applying it. Mayo Clinic recommends antibiotic ointment only if the crack shows early signs of infection.
When should I see a doctor for cracked skin?
Seek medical care if the crack is deep enough to bleed significantly, has red streaks or pus, feels hot to the touch, or is associated with a body temperature above 99.5 °F. Chronic cracked skin that does not respond to home care may signal an underlying condition like eczema or contact dermatitis that needs specific treatment.
