Some ingredients become trends.
Others are fundamental in dermatology.
Urea belongs to the latter.
WHAT IS UREA?
Urea is a molecule naturally present in healthy skin. It forms part of the skin’s Natural Moisturising Factor (NMF), a group of substances responsible for maintaining hydration, supporting barrier function and preserving skin comfort.
When skin becomes dry, sensitive or compromised, levels of these natural moisturising factors can decrease. This often leads to discomfort, tightness and increased sensitivity.
HOW DOES UREA WORK?
When applied topically, urea acts primarily as a humectant, helping the skin attract and retain water.
It also supports the skin barrier and improves the skin’s ability to maintain hydration over time. At appropriate concentrations, urea can help soften rough, dry or uneven areas of skin while remaining well tolerated by sensitive skin types.
WHY IS UREA USED IN DERMATOLOGY?
Urea has been used in dermatological care for decades.
Its effectiveness, tolerability and versatility have made it one of the most widely recommended ingredients for the care of dry, sensitive and barrier-impaired skin. Unlike many ingredients that cycle in and out of popularity, urea has remained relevant because its role in supporting healthy skin is well understood.
KEY BENEFITS OF UREA
- Supports the skin’s natural barrier
- Helps retain moisture
- Improves long-term hydration
- Softens rough or dry skin
- Supports sensitive and compromised skin
- Suitable for daily use
WHY WE CHOSE UREA
At PURO, we prefer ingredients with a long history over ingredients with a short moment.
We chose urea not because it is new, but because it continues to work.
REPAIR No.1 was developed around a simple principle: healthy skin rarely requires more intervention. It requires consistent care, well-tolerated ingredients and formulations designed for repeated use.
Some ingredients promise transformation.
Others help the skin function as it was designed to.
We prefer the latter.
