Tend Skin is really only useful for ingrown hairs. It's basically a highly effective exfoliant. It is TOTALLY WORTH THE PRICE if you get really bad ingrown hairs. I have used it for over 10 years. I get ingrown hairs from shaving my legs and waxing body hair. Tend skin makes this bearable, otherwise I'd have to go all hippie and stop shaving all together. I use it once or twice a day, especially in summer. There is another product on the market that has similar ingredients in a gel roll-on, but it isn't strong enough to work.
Drawbacks: The price, obviously. You have to use it daily, especially after waxing. It is a liquid, and most easily applied like toner with a cotton ball. If you use your hands to apply this liquid like a lotion it works, but your hands get peely skin. I like to use latex gloves. Tend Skin makes fake tanning difficult; because it exfoliates so well, your fake tan with disappear faster. It smells harsh until it dries (2 minutes) I would not use it on sensitive facial skin. And it doesn't get rid of zits, unless they are ingrown hairs. Despite what the directions indicate, it's VERY IRRITATING ON RAZOR BURN or SKIN THAT HAS JUST BEEN SHAVED.
