Rosacea is also known as rosacea. Rosacea cannot be cured and its treatment focuses on suppressing the symptoms. Photorejuvenation can improve the clinical symptoms of rosacea and improve the condition of the skin. Rosacea is a chronic inflammatory skin disease with persistent erythema and capillary dilatation that occurs in the middle of the face, and is characterized by symmetrical erythema on the nose, cheeks, forehead, and jaw. The use of photorejuvenation treatment for patients suffering from rosacea can improve oily skin by utilizing intense pulsed light to improve the symptoms of erythema and capillary dilatation, as well as to regulate and inhibit the function of sebaceous glands. However, clinical treatment usually needs to be combined with medication such as erythromycin and benzoyl peroxide under doctor’s supervision. Potential adverse effects of laser treatment include abnormal skin pigmentation, blister formation, ulceration and scarring. Therefore, patients are advised to go to regular medical institutions, and pay attention to facial cleanliness and hygiene, avoid the use of irritating substances, and pay attention to physical sun protection.
