Asking for Q Switch Laser Patch Test Experience at Kaya and a few more related queries

Hi All, I have booked myself for a Q switch laser patch test at Kaya for my freckles and melasma this Thursday. Here are a few of my related queries :

  1. How was your experience should you have done it, especially do share if it was at Kaya?
  2. Did they try to over-sell their products?
  3. What are the precautions that you have to use after the patch test is done?
  4. Can you continue to use the actives post the patch test? (Glyco 6% cream and Depiwhite Advanced Depigmentation cream - Dermatologist recommended, but I am yet to purchase and start. I thought I will wait for the Patch test to be done)
