Urea for cracked heels, 20% or 30%: use Lava Derm Urea 20% Cream for very dry, rough heels with unbroken skin. Lava Derm Pure-Foot is a 30% urea gel with salicylic and lactic acid, for a thick, rough patch on skin that is not split open. Lava Derm Vaseline Cream holds moisture in; an open or bleeding split needs a pharmacist or doctor rather than a stronger product.
Key points
- The 30% gel is not a stronger version of the 20% cream: it adds salicylic and lactic acid.
- Worn shoes and heel pressure bring the roughness back.
- Reduced feeling or circulation in the feet: ask a doctor first.
Urea for cracked heels: 20% or 30%?
For Lava Derm heel care, intact means skin that is not split open. If you cannot tell whether a crack is open, ask a pharmacist or foot-care professional before applying a concentrated product.
The American Academy of Dermatology (AAD) lists 10-25% urea among heel moisturizer options. The 20% cream sits inside that range. The 30% gel is above it and also carries acids, so it is not simply a stronger version of the cream.
Dry, thickened skin around the heel rim can split as pressure pushes the padding underneath sideways. Standing on hard floors and open-backed shoes can contribute. Moisturizing helps the surface feel supple; supportive footwear addresses part of the pressure problem. Check shoe fit and worn soles when roughness keeps returning.

What one heel-moisturizer study found
- A study of adults aged 20-35 compared three creams on foot skin hydration: placebo, 5% urea and 20% urea.
- 60adults
- The 20% urea cream beat placebo at every foot site tested, including the heel. The 5% cream did not beat placebo at the heel, and 5% and 20% did not differ significantly.

What changes in the Lava Derm formulas
Urea holds water in the outer skin and softens its dry, built-up surface. The 20% cream also contains hyaluronic acid, which helps skin retain moisture, and ceramides and lipids, fats that help skin hold water. Vitamin E and panthenol support comfort; panthenol is a soothing moisture ingredient. The urea range is fragrance free, but check the full ingredient list for your own sensitivities.
The gel adds salicylic acid, lactic acid and ammonium lactate to urea for rough-surface care. The 30% refers to urea only; the acid percentages are not on the pack. Ammonium lactate is a lactic-acid salt that holds water. Gel texture does not mean it is milder than the cream.
Petrolatum reduces moisture loss, glycerin attracts water and lanolin softens skin in the vaseline cream. It is a multi-ingredient cream, not plain petroleum jelly.

An evening routine without extra peeling steps
Try a small patch of intact skin before first use on a new area. Keep baths and showers to 5-10 minutes. AAD also mentions damp skin; these three products say dry skin, so follow the product. Choose a gentle cleanser.
Choose one formula per area. As an ingredient, urea can increase how much of another product gets into skin. If you use a medicine there, ask before adding urea or acids.
Check, clean, apply, then leave it alone
Inspect
Look for a split, bleeding, drainage or a new change. Stop the cosmetic routine on affected skin and use the help guide below.
Clean and dry
Wash gently, then pat dry. Dry feet thoroughly before the gel, including between the toes.
Apply your choice
Massage the 20% cream into rough heels until absorbed. For the gel, apply a generous layer only to its localized rough, intact target area and massage until absorbed.
Night handling
Leave the gel on overnight; rinse residue in the morning if desired. For the vaseline cream, warm a generous amount briefly between palms and massage until absorbed.
Do socks make heel cream work better?
Socks are optional. The AAD suggests plain petroleum jelly at bedtime and says socks keep grease off your sheets. For the foot gel, let it absorb before socks. Do not wrap the foot in plastic: no product direction includes it.
How long should you wait for softer heels?
Assess dryness, roughness and comfort as you follow the label. Check how the skin feels rather than waiting for sheets of skin to peel. Results vary.
DermNet advises a foot-care assessment for severely cracked heels or if a cracked heel has not improved after a week of self-care. Bring the product name, describe your routine and mention pain or skin changes. Do not wait for that checkpoint if a warning sign appears.
A checkpoint for action
- During use
Review comfort
Follow the label and check dryness, roughness and comfort rather than visible shedding.
- After a week
No improvement? Ask for an assessment
For a cracked heel that has not improved, ask a foot-care professional. Severe cracking needs assessment sooner.
- At any point
A warning sign changes the plan

Common mistakes: scraping and extra products
Moisturizing and removing thick skin are different goals. NHS guidance allows gentle filing for suitable low-risk feet, but advises against cutting hard skin yourself. A blade can remove too much skin; do not make scraping a preparation step for an acid gel.
Do
- Wear supportive, well-fitting shoes and check the heel area regularly.
- Keep bathing gentle and dry toe spaces carefully.
- Ask a foot-care professional about hard skin that repeatedly returns or makes walking uncomfortable.
Avoid
- Cutting or shaving hard skin with blades or scissors.
- Adding aggressive filing, a peel or another strong exfoliant to the acid gel.
- Using homemade strong acid mixtures on the heel.
- Putting the 20% cream or the foot gel on the face, eyes or genital skin.
When to ask a pharmacist, doctor or foot-care team
With diabetes, poor circulation or reduced foot sensation (neuropathy), ask a doctor before thick-skin care. Reduced sensation can hide pain. Older adults and people with weakened immunity should also ask before corn or callus self-care.
Ask a pharmacist about minor concerns or product choice. Deep painful cracks, bleeding or trouble walking need a doctor or foot-care professional. Heat, swelling, spreading redness or feeling unwell can indicate infection; redness may be harder to see on darker skin.

Lava Derm Urea 20% Cream
Questions, answered clearly
Do I need socks after applying heel cream?
Socks are optional. AAD suggests them to keep petroleum-jelly grease off bedding. Let the foot gel absorb before putting on socks; a sock is not a required application step.
Can I put urea on an open heel crack?
Keep urea and acids off open or bleeding skin. Ask about care for the split; deep painful cracks or discharge need prompt assessment.
Is 30% urea better than 20% urea for cracked heels?
Not automatically. The 30% gel adds salicylic and lactic acid and is for thick, rough patches on intact skin. For dry, rough heels the 20% cream sits inside the AAD’s 10-25% range. In a study of 60 adults, 20% urea beat placebo for skin hydration, but no significant difference was detected between 5% and 20%.
Is petroleum jelly the same as urea cream?
Urea holds water and softens skin; petrolatum reduces water loss. Lava Derm Vaseline Cream also contains glycerin, liquid paraffin and lanolin, so follow its own directions rather than treating it as plain petroleum jelly.
How long before my heels feel softer?
Follow the label: the 20% cream twice daily until skin feels soft, the gel morning and night. Judge dryness and comfort rather than waiting for peeling. If a cracked heel has not improved after a week, ask a pharmacist or podiatrist. Go sooner for severe cracking, pain, bleeding or discharge.
