Do photon rejuvenation! More than 300 times, I have a cousin who has done it and her face is much whiter! It's made by the Fourth Hospital of Yangming East Road, donghu district, specializing in dermatology! It's just that there are many people, so it's best to make an appointment in advance, so as not to queue up for registration! It's free anyway! You can find their official website appointment by searching Nanchang No.4 Dermatology Clinic!
