Life-saver for hands in pain
Size: 5.1 Ounce (Pack of 2)
This is my favorite hand cream. We're in PA and I keep a tube of this by the kitchen sink, in my bedroom, the bathroom, and in my car. I use it all the time and it saves my hands. I discovered it by chance at a store one time and I've tried many products (used to work in Healthcare so was constantly hand-washing). I like O'Keefe's Working Hands all right, and Gold Bond healing hand cream used to be my favorite, but this replaces both. It's so helpful for my 5 year old, too, whose hands get super dry and cracked if we don't keep up with this. It's great stuff. Ever since I discovered it, I haven't been able to find it in stores again. It's always out of stock, so I guess others have figured it out as well!

Must Have Beauty Product
This one of my favorite and must have beauty products. Works so quickly for chapped lips and just keeping my lips soft every day. The formula isn’t sticky at all and you can really feel how hydrating and nourishing it is

The best lip balm!
I’m so addicted to this lip balm!!! If you have secret chapped lips this will fix it in a day or two!!! And even if u don’t, it keeps your lips soooo soft!!! A bit pricey but it goes on sale a lot so watch for that.
