    Area of Science:

    • Dermatology
    • Biochemistry

    Context:

    • Urea is a natural compound with significant effects on skin physiology.
    • Its application in dermatotherapy is of considerable interest.

    Purpose:

    • To elucidate the dual effects of urea on skin hydration and barrier function.
    • To understand the implications of urea concentration on epidermal structure and active ingredient permeation.

    Summary:

    • Urea at low concentrations moisturizes the stratum corneum.
    • High concentrations of urea can impair skin barrier function due to its mucolytic and keratolytic properties.
    • Urea influences epidermal proliferation and can enhance the penetration of other active ingredients.

    Impact:

    • Understanding urea's concentration-dependent effects is crucial for safe and effective dermatological applications.
  • Highlights the need for medical supervision when using high-concentration urea formulations for conditions like dry skin.
