This is my first time getting a whitening injection. Are there any precautions I should take?

With increased outdoor activities, my skin tone has become dull and discolored not only on my face but also on my entire body, making restorative care urgently needed. I am considering visiting a dermatologist to receive the White Jade Injection, which provides deep skin tone-up and antioxidant effects. After searching for reviews and information, I noticed that many people combine it with the Cinderella Injection for systematic tone management. I would like to know the typical interval between Cinderella Injections and the minimum number of sessions required to see significant tone improvement without putting strain on the skin. Please provide guidance on the tone-up synergy that occurs when combining the White Jade Injection and Cinderella Injection at appropriate intervals, as well as a recommended treatment schedule.
