Photorejuvenation has multiple effects, and can remove various skin discolorations such as freckles, sun spots, age spots, etc. It can also improve skin dullness and uneven skin tone, reduce pigmentation, and treat facial capillary dilation, facial flushing, rosacea, enlarged pores, facial skin roughness, acne marks, and comprehensive skin aging. A single photorejuvenation treatment can usually last for about 3-6 months. In addition, candidates also need to combine with topical moisturizing and repairing creams to maintain the already pink skin for a longer period of time. It is generally recommended to use topical propylene glycol cream or hyaluronic acid gel, both of which have good moisturizing and repairing functions, which can increase the local water content of the skin and make the skin more hydrated. In daily life, candidates should try to reduce the stimulation of the facial area, less alcohol, less chili, fennel and other spicy and irritating foods. If you need to wear makeup, it is best to wear light makeup, because too much makeup can cause some obstructive changes to the skin, allowing acne to grow on the face, thus affecting the effect of photorejuvenation.
