If you struggle with dry, cracked heels, thick calluses, or stubborn rough patches on your feet, hands, elbows, or knees, you've likely come across Urea Cream 40% with Salicylic Acid 2%. This keratolytic foot cream works by softening and exfoliating dead skin while repairing and hydrating the skin barrier. But if you've ever noticed a white, dried-up thin residue after using it, you might wonder if something went wrong. Don't worry, that's completely normal.
Why Urea + Salicylic Acid Works
-
Urea 40%: A keratolytic ingredient that breaks down thickened, hardened skin while deeply hydrating.
-
Salicylic Acid 2%: Helps loosen dead skin cells and enhance exfoliation.
-
Together, they soften calluses, rough heels, and repair cracked skin, making it easier for your skin to absorb moisture.
How to Apply Urea Cream
To get the best results from your Urea 40% Foot Cream, follow these steps:
-
Clean and dry the area — Ensure your feet, hands, and elbows are freshly washed and completely dry.
-
Apply a generous layer — Massage the cream into heels, calluses, or rough patches. Don’t be afraid to use enough product to cover thickened areas.
-
Seal in moisture — For best absorption, cover the area:
-
On feet, wear cotton socks after applying.
-
On elbows, cut up an old long sock to create a protective sleeve. This tip keeps the cream from rubbing off on clothing or bedding.
-
Leave it overnight — Many people prefer to apply the cream at night, allowing it to work for 6–8 hours while they sleep.
-
Rinse or wipe off any residue — This dried product is normal, since the product is using 40% Urea, the highest strength for the best results.
What’s the White Residue? Is It Normal?
Yes, the dried-up white product is expected. When urea at 40% and salicylic acid break down keratin and dead skin, the cream can leave behind a thin chalky or flaky layer. This doesn’t mean the cream didn’t absorb, it means it has been working to exfoliate. Rinse or wipe it off, and you'll notice softer, smoother skin underneath.
Pro Tips for Maximum Results
-
Be consistent — Apply twice a day until rough patches noticeably soften, then reduce to a few times a week for maintenance.
-
Exfoliate first — Use our Callus Remover to gently lift away dead skin cells. Then hydrate to lock in moisture and softness.
-
Protect the area — After application, cover the treated skin with socks or fabric sleeves to help the product stay in place and reduce transfer onto clothing or bedding.

Final Thoughts
Urea Cream 40% + Salicylic Acid 2% is one of the most effective treatments for rough, dry, or thickened skin. While the white residue may look unusual at first, it’s simply part of the exfoliating process and proof that the cream is at the highest strength and doing its job. For best results, apply on targeted area twice per day with socks or protective fabric, let it work while you sleep or go about your day. With consistent use, you'll notice smoother, softer, and healthier-looking skin.
