I started with twice a week from the outset. This was because I had had LS for years before getting a proper diagnosis and at that point my skin was very thin and I expect my dermatologist wanted be conservative in her approach. In other cases, if the woman has thicker or less fragile skin a more aggressive treatment might be suitable. I would ask Why a given treatment is being recommended for you. Also, if a little bit will do the trick, so much the better, why use more. If a little bit doesn’t do the trick, time to re-evaluate.
