Hello dear,
There are many causes of hypopigmentation or Leucoderma and if your dermatologist has prescribed you placentrex then he/she might be suspecting vitiligo
Another reason for your white spots could be healing folliculitis post threading/folliculitis
Even Iron deficiency can also lewd to hypopigmented patches so it can be anything
I would suggest you to share your pictures and other details are also required for proper diagnosis and treatment
Next Steps
