Skin sensitivity and skin microbiota: Is there a link?

Area of Science:

• Dermatology
• Microbiology
• Skin Physiology

Background:

• Sensitive skin is characterized by unusual sensations like stinging or burning, often without visible signs like redness.
• Current hypotheses suggest a hyper-reactive cutaneous nervous system and impaired skin barrier function contribute to sensitive skin.
• Emerging research indicates a potential role for the skin's resident microorganisms (microbiota) in the development of skin sensitivity.

Discussion:

• This review examines the intricate relationship between the skin microbiota, the integrity of the skin barrier, and the manifestation of sensitive skin.
• It explores how alterations in the skin's microbial community may influence skin barrier function and nervous system reactivity.
• Understanding these interactions is crucial for developing targeted strategies for managing sensitive skin.

Key Insights:

• The skin microbiota plays a significant, though not fully understood, role in modulating skin sensitivity.
• A healthy skin barrier and balanced microbiota appear to be essential for preventing the onset of sensitive skin symptoms.
• Dysbiosis, an imbalance in the skin microbiota, may exacerbate skin sensitivity by compromising barrier function.

Outlook:

• Further research is needed to elucidate the precise mechanisms by which the skin microbiota influences skin sensitivity.
• Investigating the therapeutic potential of modulating the skin microbiota could lead to novel treatments for sensitive skin.
• Future studies should focus on personalized approaches targeting the skin microbiome for sensitive skin management.
