Rosacea is a common skin condition that primarily affects the face, causing redness, visible blood vessels, and sometimes small, red, pus-filled bumps. It often appears in flare-ups and can be triggered by factors such as sun exposure, stress, hot beverages, and certain foods. The exact cause of rosacea is not fully understood, but it may involve a combination of genetic and environmental factors. Treatment options include topical medications, oral antibiotics, and lifestyle changes to help manage symptoms and reduce flare-ups. Regular consultation with a dermatologist can provide personalized care.
