Rosacea mostly occurs in middle-aged people, more often in women, and can be accompanied by acne or seborrheic dermatitis. The most commonly seen type in clinical settings is erythematotelangiectatic rosacea, primarily appearing in the central parts of the face, especially on the nose, cheeks, forehead, and chin, with symmetrically occurring erythema. Different stimuli, such as environmental changes, temperature fluctuations, consuming hot beverages, alcohol, spicy foods, exercise, and bathing, can all cause persistent blushing and erythema, often accompanied by dry skin, a burning sensation, or a stinging feeling. To reduce erythema, it is first important to protect against the sun to avoid damage to the facial skin barrier by ultraviolet rays. It is also necessary to avoid excessive cleansing, enhance moisturizing and skin-nourishing treatments, and avoid extreme heat or cold, as well as the adverse stimulation of mental stress. Alcohol consumption and spicy or irritating foods should be avoided. Local cold compresses may be appropriate, and for severe and recurrent cases, internal administration of Chinese herbal medicine is recommended to clear heat, cool the blood, and reduce redness.
