It's been 2 weeks for me. I used the witch hazel pads for about a week give or take a day. I still use the squirter bottle and then just pat dry with toilet paper. If i just wipe with toilet paper it kinda drys things out and the wiping motion irritates everything and makes it burn
You can use it for as long as you want. It feels so good. I am already 3 weeks and a half and use them whenever I feel irritated.
Ur spoused to do it for 4 weeks
