Rosacea is a chronic skin condition that causes redness, visible blood vessels, and occasional acne-like bumps, typically on the face. It can be triggered by factors such as sun exposure, spicy foods, alcohol, stress, and extreme temperatures, with genetic and immune system factors also playing a role. Symptoms may worsen over time, leading to persistent flushing, skin sensitivity, and in some cases, thickened skin, especially on the nose (rhinophyma). While there is no cure, treatments such as topical and oral medications, laser therapy, and lifestyle modifications can help manage symptoms and reduce flare-ups.
