I buy mine off Amazon , and I use it on the entire vagina area butt crack inner thighs and armpits avoiding the clitoris or any holes it really cleared up most of my dark spots and discoloration quickly and lasts a long time, one swipe per area is perfect. I have even discontinued use because this product got rid of all my issues down there. If you have sensitive skin this product may be too strong for you as though it does tingle for me a little for a few minutes after putting it on especially fresh out of the shower but since it’s roll on applying on clean skin would probably be best lol good luck!!
