Environmental and Lifestyle Triggers of Rosacea.

Rosacea is a chronic inflammatory skin condition characterized by facial erythema, flushing, telangiectasias, papules, and pustules. Its pathophysiology involves a multifactorial interplay of genetic, immune, microbial, and neurovascular factors contributing to inflammation and vascular dysregulation. Environmental and lifestyle triggers are important contributors to disease exacerbation. In this review, we highlight 4 major modifiable triggers-UV radiation exposure, temperature fluctuation, skin care practices, and diet-and their roles in rosacea pathogenesis and management. Lifestyle modifications targeting these triggers combined with topical, oral, and/or laser therapies can improve disease control. A holistic, patient-specific approach to treatment that involves education on environmental influences and tailored management strategies is essential.
