Impressive
Style: Updated Formula
Nice thick cream! I even saw results (skin improvement) within days. I like this way better than their Cicalfate+, as it’s easier to rub in, less greasy, and doesn’t have the water vs cream separation issue. I’m not a huge fan of the pump top for this one, but at least it’s a tube instead of a solid canister (where you can’t see how much is left or get to the last bit).

Very smooth and also affordable when buying the 3 bottle set.
Scent: Unscented, Size: 20.3 Fl Oz (Pack of 3)
I just love this lotion. I am 78 years old and need extra moisture daily. I can tell you how this lotion has made such a difference in my mature skin. I use it every morning after a shower and nightly for over night protection. I love that it's unscented and doesn't take away from my cologne that I love, where other lotions overwhelmed my cologne. Anyway I love it so much that I bought the 3 bottle package to have it always on hand. I am very picky with my face lotions and serums and I use this lotion on my face after my serums. It makes my makeup go on so smoothly and seems to help not having to reapply during the day. I just can't say enough about it and this lotion will be my go to body lotion as well. I am constantly getting compliments on how soft and smooth my skin looks and feels and this is saying something when approaching 79 years young!!!
