Urea cream helps. Here is what it does not address.
Urea cream is a legitimate recommendation. It softens thickened skin and draws water into the outer layer. For callused and hardened areas, particularly on diabetic feet, it does something real. The gap is what it does not do: it does not replenish the oils that diabetic skin has stopped producing. Understanding that distinction is what changes the outcome for most people.
What urea cream does
Urea is both a keratolytic and a humectant.
As a keratolytic, it breaks down and softens thickened, callused skin. This is why it is the default recommendation for diabetic foot care: feet subjected to prolonged pressure develop areas of hard, thickened skin that urea directly addresses.
As a humectant, urea draws water from the lower layers of the skin into the outer layer, temporarily increasing moisture content at the surface.
Both of these actions are useful. For thickened skin on pressure points and heels, urea cream is the right product. No one should stop using it for that purpose.
What urea cream does not address
Urea is not a lipid. It does not replace the oils the skin has stopped producing.
In type 2 diabetes, the sebaceous glands are progressively impaired by the accumulation of AGE (advanced glycation end) proteins that occur with chronically elevated blood glucose. These glands produce the skin's natural oils, particularly palmitoleic acid (omega-7), which forms the structural lipid layer of the skin barrier.
When that lipid layer thins, the barrier loses its ability to hold water and resist irritants, regardless of how much water is added to the surface. This is why diabetic skin that has been regularly moisturised with urea cream still cracks, still feels perpetually dry between applications, and still develops tears and breaks at relatively minor provocation.
The skin is not resistant to treatment. It is receiving the wrong treatment for the component that is actually failing.
The mechanism difference
Most moisturisers, urea cream included, work within the water component of the skin barrier. They pull water in or slow water loss. This addresses the hydration function of the barrier.
Mac Pure works within the lipid component. Macadamia oil contains 17-22% palmitoleic acid, the same fatty acid that human sebaceous glands produce as part of sebum. Applied consistently, it replenishes the structural oil layer that diabetic skin can no longer produce in sufficient quantities.
These two approaches are not competing. They address different components of the same barrier.

Who uses both
For many people with diabetic skin, using both products is the most effective approach.
Urea cream on the feet, for thickened and callused areas. This is where the keratolytic action is most needed and most effective. Your podiatrist's recommendation stands.
Calm+ on legs, shins, and broader body skin. This is where the lipid deficit is the main problem and where a product that replenishes palmitoleic acid directly addresses what urea cream cannot.
Common questions
Is urea cream or Mac Pure better for diabetic skin?
They address different components of diabetic skin's barrier deficit. Urea cream softens thickened skin and adds surface hydration. Mac Pure replenishes the skin's oil layer, which diabetic skin stops producing adequately over time. For most people with long-term type 2 diabetes, the most effective approach uses urea cream on feet for calluses and Mac Pure on broader skin for the lipid deficit.
Why does my skin still feel dry even with urea cream?
Urea cream addresses surface hydration but not the oil layer of the skin barrier. Diabetic skin loses oil-producing capacity over time through impaired sebaceous gland function. Adding water to a barrier that lacks oil provides temporary relief but does not fix the underlying deficit.
What concentration of urea cream should diabetics use?
For feet with significant thickening and callusing, concentrations of 20-25% are commonly recommended. For general body skin, lower concentrations of 5-10% are more appropriate. Your podiatrist can advise on the right concentration for your specific situation.
Can I use Mac Pure alongside my urea foot cream?
Yes. Calm+ is designed for legs and body skin and complements podiatrist-recommended urea foot cream. Using both addresses different components of diabetic skin's barrier deficit.
Formulated for diabetic skin. Addresses what urea misses.
Calm+ delivers 17-22% omega-7 (palmitoleic acid) directly to the skin barrier, replenishing the fatty acids diabetic skin can no longer produce in adequate amounts. Fragrance-free, Australian made, and available in 250ml and 500ml.
