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!!!

MY FAVORITE HAND LOTION FOR DECADES
Scent: Unscented, Size: 20.3 Fl Oz (Pack of 3)
This particular version of Vaseline Intensive Care hand lotion is the best on the market. I have used it for decades, and though I have tried to other brands, keep coming back to this. It moisturizes very well, is not greasy and can be used anywhere on the body. Highly recommend!
