Feels great after cheap work soap hand washes
Size: 11 Fl Oz (Pack of 1)
This stuff is great. I reapply ALL the time because I have it at work.I wash my hands frequently and the soap at the work is very harsh, cheap, and generally just terrible on the skin.I use this after every wash and it leaves my hands and arms soft and moisturized. I have also received compliments on how nice my office smells after I apply it. While that might make it sound as if the scent is very strong, it isn't. It's nice, and lingers for a bit, but it is not overpowering or overwhelming. The tub goes a long way, and the container at my desk has lasted for months, and a little goes a long way. I appreciate that the container seals well and doesn't leak. Sometimes when I take other lotions on the go with me, I worry that the little flap top will open up and make a mess. That is not a problem with this jar AT ALL. It is easy to close and stays closed, even when I throw it in my bag and then throw my bag around a bit in transport.

Wonderful for my super dry skin
Size: 11 Fl Oz (Pack of 1)
This moisturizer is great, I have no complaints. I have VERY dry skin and live in Chicago - where winters only make matters worse. This product has actually healed my dry, cracked skin and improved it's overall condition. It absorbs quickly and the scent is mild. I apply it after exfoliating in the shower at night and when I wake up, my skin is soft and looks healthy.
