I took a tip from some pros on here who were applying it to their foot. I do that now and it all seems good.
My meno specialist told me to apply it on my bikini line. Which I did... a few new hairs dis grow over time (it had all been lasered over 10 years ago)... but the main reason I stopped applying it there was that I found the skin was darkening.
However, since getting my new tostran prescription, I've found the formulation to be less harsh on the skin, so maybe this darkening wouldn't happen now.
Good luck.... oh, one more thing, you might find that half a pump a day is quite a lot. But you can experiment, see how you go.
Good luck xx
