[Asteatotic dermatitis: etiology and pathogenesis].

Area of Science:

• Dermatology
• Pathogenesis of skin diseases
• Cutaneous barrier function

Background:

• Asteatotic dermatitis (AsD) is a prevalent skin condition marked by xerosis, pruritus, and erythema.
• It arises from compromised skin barrier integrity due to factors like aging, climate, and hygiene.
• Dysfunctional sebaceous and sweat glands, alongside increased transepidermal water loss, contribute to AsD.

Purpose of the Study:

• To review the current understanding of asteatotic dermatitis etiology.
• To explore the underlying pathogenesis of AsD.
• To offer novel perspectives for AsD diagnosis and treatment.

Main Methods:

• Literature review of existing studies on AsD.
• Analysis of research focusing on skin barrier damage, age, gender, and bathing habits.
• Inclusion of recent studies investigating systemic diseases and drug-related factors in AsD.

Main Results:

• Traditional research linked AsD to skin barrier damage, age, gender, and bathing habits.
• Emerging research highlights associations between AsD and systemic conditions or medications.
• The precise pathogenesis of AsD remains incompletely understood.

Conclusions:

• Understanding AsD etiology and pathogenesis is crucial for clinical practice.
• Further research is needed to elucidate the complex factors contributing to AsD.
• This review provides a foundation for developing improved diagnostic and therapeutic strategies for AsD.
