Natural Urea Callus Cream

Heel fissure

Why Natural Urea Callus Cream is superior to everyday lotions for care of thick, heavy callus

Soft, supple skin is dependent upon daily skin care to cleanse and hydrate your skin.  Most over-the-counter skin care products contain a combination of agents that exfoliate superficial cells in the epidermis, hydrate the skin and act to repair defects in the skin.  These agents can be broken down into three basic categories:

  • Humectants – act to soften the epidermis by attracting moisture from the dermis.  Examples of humectants include ammonium lactate and lactic acid.
  • Occlusives – decrease the rate of evaporation.  Examples of occlusives include mineral oil and petroleum jelly.
  • Emollients – make skin soft and slippery by filling superficial defects in the epidermis.  Examples of emollients include lanolin and jojoba oil.

What is the difference between dry skin of the foot and heavy callus on the foot?

Callus is a response by the skin to thicken and create a protective layer.  The response by the skin to form callus is often caused by an irritation such as two toes rubbing together or an irritation from a shoe.  A common spot for heavy callus on the foot is the rim of the heel.  In the case of heel callus, the irritation to the skin is due to tension and not friction.  Here’s a simple example of what contributes to the tension in the skin of the rim of the heel that causes thick callus and heel fissures.

Fill a water balloon at the kitchen sink.  Tie the neck of the balloon and set the balloon on the counter.  Lift the balloon and set it down on the counter again, and again.  In each case, as the balloon in lifted and set on the counter, the walls of the balloon are stretched creating tension.  Now consider the padding of the heel.  With each step, the padding and skin of the heel act much in the same way as the example of the balloon.  Lift the heel and then compress it with weight bearing.  The skin surrounding the rim of the heel responds by thickening and subsequently fissuring resulting in deep, painful cracks in the skin.

Chemical debridement of callus with 20% urea

Urea is a naturally occurring nitrogen crystal that has many used in the food and cosmetic industry.  In skin care, urea is most commonly used as a humectant, hydrating skin by drawing moisture into the superficial skin known as the epidermis.  As the concentration of urea increases in a skin product, urea acts as a keratolytic agent.  Keratin is a structural protein that is the primary building block of skin, hair, nails (along with horns and fish scales).  Keratolysis is the process of breaking down the bonds between the keratin molecules.  With repetitive use of Natural Urea Callus Cream, superficial callus can easily be chemically debrided by this safe and natural skin care additive.

Step by step use of Natural Urea Callus CreamNatural Urea Callus Cream

Natural Urea Callus Cream contains 20% urea.  This high concentration of urea acts as a keratolytic agent, slowly and gently debriding thick, heavy callus.  Although the high concentration of urea in Natural Urea Callus Cream can act to break down thick, heavy callus, you still need to physically remove the callus with a pumice stonecallus file or safety corn and callus trimmer.

1. Apply Natural Urea Callus Cream twice daily to a clean and dry callus.  Wash your hands carefully after use.

2. Once the callus begins to soften, use a mechanical means of callus debridement such as a pumice stone.

3. Repeat the application of Natural Urea Callus Cream as needed.

It’s important to understand that management of calluses requires ongoing care.  Calluses may become worse with seasonal changes but ongoing care is essential to success.
