I can't believe I'm writing a review for a product like this haha. But I'm writing it because it is so good! ^^; The scent is beautiful and doesn't smell artificial or overbearing (I bought the Herb-fore scent). I use about 3 drops every day on a liner, and even on my pads whilst on my period. The scent never turned weird or unpleasant, but stayed beautiful. The other reviewers weren't kidding when they say it can boost your confidence haha. It's nice to always smell like a pretty perfume. This can even be used as a normal perfume oil elsewhere on your body, as the scent lasts all day. I'm hooked. Seriously. I definitely want to buy more of this haha.
I don't know if this really prevents certain infections that can happen down there, but I have been using it daily for over a month and there were no adverse reactions.
Oh, if you apply it directly on your underwear, if it's cotton, don't worry too much about the oil staining. I use reusable cotton cloth liners and pads, and it has always washed out no problem. Just soak the underwear/cloth pads in water for a couple of hours and hand wash.
I will definitely buy more of this once the shipping situation resumes to normal. This stuff is awesome! :D
