Rosacea can be treated with lasers. Rosacea, also known as “rosacea”, is a chronic inflammatory skin disease that occurs in the middle of the face, mainly involving the blood vessels of the face and the peripheral units of the sebaceous glands of the hair follicles, manifesting itself in the form of redness of the skin, as well as erythema, papules, pustules, and dilated capillaries. The lasers usually used to treat rosacea include yellow infrared light, intense pulsed light, and pulsed dye laser. Among them, yellow infrared light is suitable for the acute swelling period (skin anti-inflammatory, promote skin metabolism); intense pulsed light can improve the symptoms of erythema and capillary dilatation, can also be used for papule pustular patients, but should be used with caution in the acute swelling period of the lesions; pulsed dye laser can improve the erythema and capillary dilatation, but need to pay attention to its adverse effects (such as purpura, secondary pigmentation, etc.). It is recommended that patients go to regular hospitals, under the guidance of professional doctors, choose the appropriate treatment method to receive treatment.
