It can do a ton of other stuff, too, like reduce redness, soothe irritation, heal cuts, and reduce oil and inflammation.

Promising review: “I buy this when my other bottle is only half empty — that’s how much I don’t want to be without it. The smell is so good that even if it didn’t work amazing wonders on my skin, I would use it just for that. But it does work! Because of this toner, my skin is brighter, more even, and just plain pretty. It feels moisturizing and clean, without giving your skin that tight feeling. I have pretty sensitive skin, but it doesn’t burn at all. It tightens pores and helps with all skin needs, whether you break out a lot, are young or old, or have dry or combination skin — it’s universal.” —Gail Swearngin

Heads up — reviewers love these undies, but suggest sizing up!

Promising reviews: “I use it all the time, especially when traveling and overnight. It prevents leakage.” —ruth

“I deal with PCOS and endometriosis, which make my periods HEAVY for the first three to four days. I ordered two pairs of these underwear. They absorbed better than a pad, were comfortable, and the top layer stayed dry. Amazing. I had been thinking about buying the really expensive version of these underwear, but the price was ridiculous. These underwear do exactly what I need them to do for half the price. They are easy to hand wash and hang dry. I plan on ordering more. The stitching and waistband are solid and they don’t bunch, don’t ride up, and don’t roll. They provide front and back coverage. They’re literally perfect. If you’re on the fence about these, I urge you to give them a try. They’ll save you money (no pads or tampons needed, and you won’t stain your regular underwear and have to replace them).” —drsmaw

This works on mosquitoes, bees, wasps, biting flies, sea lice (sea lice?!), and more!

Promising review: “These are great! I was in Mexico, being eaten alive by mosquitos and going crazy itching/trying not to scratch the bites. Ordered this tool, and my husband brought it with him when he joined me in MX and it immediately alleviated my problem. I used it as soon as I was bit and the itch just never happened. It even works on older much-scratched bites, though you may have to use it a few times in order for it to take all the itch out. I will say that there are a few places I found it difficult to use it on, the side of my wrist, a toe, etc. Yes, there is a smaller focus head, but it can be difficult to get it right over the spot as needed. I bought two and won’t travel without one! The review process requires that you rate the longevity of this tool, I can’t really speak to that as I haven’t had it long. I worked perfectly for the week I used it though.” —Raven Squire
