Rosacea is a chronic skin condition that causes persistent redness, visible blood vessels, and skin sensitivity—often appearing on the cheeks, nose, forehead, and chin. Some individuals may also develop small red bumps that resemble acne, along with burning or stinging sensations. While the exact cause is unknown, rosacea is often triggered by heat, stress, spicy foods, and sun exposure. Though rosacea has no cure, targeted treatments can help manage flare-ups and restore an even skin tone.
