Cracked heels usually form when thick, built-up dry skin loses flexibility and splits under the everyday pressure of standing and walking, not just from cold weather or a dry house. The fastest way to soften and smooth that buildup is a cream that combines a humectant like urea with a gentle exfoliant like salicylic acid: urea draws water into the outer layer of skin and helps break down hardened tissue, while salicylic acid loosens the bonds between dead skin cells so they shed instead of thickening into calluses. Uexim's 42% Urea Cream with 2% Salicylic Acid is formulated as a concentrated foot and hand moisturizer for exactly this kind of rough, dry patch, rather than an everyday all-over lotion. Here's why heels crack in the first place, how urea and salicylic acid actually help, and how to build them into a routine that keeps working between applications.
What Actually Causes Heels to Crack?
According to the American Academy of Dermatology, cracked heels are typically caused by dry skin that thickens under the pressure of standing and walking, especially in open-back shoes or sandals, dry climates, and with age. As the skin on the heel loses moisture and elasticity, it hardens into a callus, and when that hardened skin is stretched by weight-bearing pressure, it splits into visible cracks, called fissures. Once cracks form, they tend to get worse without intervention, since dry, thickened skin has less give.
How Does Urea Cream Help Dry, Cracked Heels?
Urea is a humectant, meaning it pulls water into the outer layer of skin, and dermatology sources note that at higher concentrations it also has a keratolytic effect, which is a gentler way of saying it helps loosen and soften thickened, hardened skin so it can shed more easily. This combination of moisturizing and softening is why urea-based creams are a commonly recommended first step for cracked heels. Uexim's cream uses a 42% urea concentration, which sits at the higher end typically used for tough, callused areas like heels rather than facial skin.

What Does Salicylic Acid Add to a Foot Cream?
Salicylic acid is a beta-hydroxy acid that works differently from urea: instead of drawing in moisture, it helps loosen the bonds holding dead skin cells together on the surface, so flaky, rough skin sheds more evenly rather than building up into a hard callus. That's why it's frequently paired with urea in foot and heel creams: urea softens and hydrates, while salicylic acid helps clear away the surface buildup that keeps re-forming.
How to Use a Urea and Salicylic Acid Cream on Your Feet, Step by Step
- Wash and dry your feet first. A quick soak in warm water can help soften skin before you apply the cream, though it isn't required.
- Apply a thick layer to heels and rough patches. Focus on visibly dry, thickened, or cracked areas rather than spreading it thinly over the whole foot.
- Avoid open cracks or broken skin. Salicylic acid can sting on broken skin, so if a crack is deep or bleeding, treat the surrounding callus and let the crack itself heal, or check with a professional first.
- Cover with socks overnight for stubborn buildup. Wearing clean socks after applying helps lock in moisture and lets the cream work while you sleep.
- Use nightly until skin softens, then taper. Once heels feel noticeably smoother, two to three times a week is usually enough to maintain results.
Urea Cream vs. Petroleum Jelly vs. a Pumice Stone
| Method | How it works | Best for |
|---|---|---|
| Urea + salicylic acid cream | Hydrates and softens thickened skin, helps it shed | Ongoing, at-home maintenance of dry or cracked heels |
| Petroleum jelly | Seals in existing moisture, no exfoliating effect | Locking in moisture overnight, mild dryness |
| Pumice stone | Physically buffs away dead surface skin | Removing thick callus buildup, used alongside a cream, not instead of one |
Many people get the best results combining methods: gently buffing thickened, callused skin with a pumice stone, then applying a urea and salicylic acid cream to keep new buildup from hardening again.
When Should You See a Podiatrist Instead of Treating Heels at Home?
The American Academy of Dermatology recommends seeing a dermatologist or podiatrist if cracked heels are painful, bleeding, showing signs of infection like redness or swelling, or not improving after a couple of weeks of consistent at-home care. People with diabetes or circulation issues should also check with their doctor before starting a new foot care routine, since foot injuries can be more serious for that group.
Frequently Asked Questions
Can I use this cream on my hands too?
Yes, it's formulated as a foot and hand moisturizer, so it can be used on rough patches on the hands as well as the heels.
How long until cracked heels improve?
Many people notice softer, smoother skin within a week or two of consistent nightly use, though deep, longstanding cracks can take longer.
Is it safe to use if I have diabetes?
Check with your doctor before adding a new foot care product if you have diabetes or a circulation condition, since foot care needs are different for that group and a professional can advise on what's appropriate for you.
Does the cream sting on cracked skin?
Salicylic acid can sting on broken or bleeding skin, so it's best applied to the surrounding callused area rather than directly into an open crack.
Can I use it every day?
Yes, nightly use is common while heels are visibly dry or cracked. Once skin feels smoother, most people scale back to two or three times a week.
