The best time for photon rejuvenation surgery is in the season when the sun is not violent, because after photon rejuvenation, comprehensive sun protection is needed to avoid postoperative rebound and loss of therapeutic effect.

It is best to choose autumn or winter as far as possible for treatment. It will be humid in spring, which is not very helpful to the recovery of skin.

Personally, I think photon rejuvenation treatment should avoid treatment during menstruation, pregnancy and lactation, make good physical preparation about two weeks before operation, have a light diet, do not smoke or drink, and do not take drugs containing aspirin or vitamin E.
