Photorejuvenation is done by stimulating the skin with intense pulsed light to achieve whitening and rejuvenation, and results can usually be seen in about 1 week after treatment. Photorejuvenation is a popular cosmetic treatment that can effectively increase skin hydration and stimulate local subcutaneous cells to return to a hydrated and shiny level, and can be used to improve skin problems such as acne red marks, enlarged pores, hyperpigmentation and aging. The results are usually seen in about 1 week after the photorejuvenation treatment, and are manifested as brighter skin tone, finer skin texture, no jamming or reduced jamming on makeup, etc. Photorejuvenation requires multiple treatments. It is recommended to have one treatment per month and 3-5 times for one treatment. After undergoing photorejuvenation treatment, candidates should pay attention to daily skin care such as hydration, moisturizing and sun protection to enhance the effect of photorejuvenation.
