I want to know if I should stop these medications before or after laser hair removal so it doesn't cause burns or make it less effective and by how many days? Glucophage (metformin) 1000 - vitamin D 10000 iu - ferritin iron - daflon 1000. As well as topically using honey as a mask daily/using benzac AC (benzoyl peroxide) 5%. Thank you very much.
