Abstract:
Rosacea is a common chronic skin disease affecting mostly people aged 40 and above, with currently no cure. When it affects the eyelids and periocular skin, it leads to dry eye and potentially corneal damage. Research performed over the last decade shed light into the potential mechanisms leading to skin hypersensitivity and provided promising avenues for development of novel, rational therapeutics aimed at reducing the skin inflammatory state. In this review, we discuss the current knowledge on the mechanisms of rosacea in general and of periocular skin-affecting disease in particular, identify key questions that remain to be answered in future research, and offer a disease model that can explain the key characteristics of this disease, with particular emphasis on a potential positive feedback loop that could explain both the acute and chronic features of rosacea.
Insights
Rosacea is a chronic skin condition impacting those over 40, potentially causing dry eye and corneal issues. Recent research explores its mechanisms, offering new therapeutic targets for skin hypersensitivity and inflammation.
Area of Science:
- Dermatology
- Ophthalmology
Background:
- Rosacea is a prevalent chronic skin condition, primarily affecting individuals over 40.
- Periocular rosacea can lead to dry eye disease and potential corneal damage.
Purpose of the Study:
- To review current knowledge on rosacea mechanisms, focusing on periocular involvement.
- To identify research gaps and propose a disease model for rosacea.
- To emphasize a potential positive feedback loop in rosacea pathogenesis.
Main Methods:
- Literature review of recent research on rosacea mechanisms.
- Analysis of studies on skin hypersensitivity and inflammatory pathways.
- Development of a conceptual disease model for rosacea.
Main Results:
- Recent research has illuminated mechanisms of skin hypersensitivity in rosacea.
- Novel therapeutic strategies targeting inflammation are emerging.
- A proposed disease model highlights a positive feedback loop in rosacea.
Conclusions:
- Understanding rosacea mechanisms offers new therapeutic avenues.
- Further research is needed to address key questions in rosacea pathogenesis.
- A proposed feedback loop model may explain rosacea's acute and chronic features.
