Intense healing in a convenient jar!
Size: 13.5 Ounce (Pack of 1)
A great healing lotion for all over body application. I like the product being in a jar so there is no problem getting the lotion out of a bottle making this a very wise economical choice. A 72 hour intense healing lotion providing a long lasting healing experience. Highly recommended.

The texture is rich but still absorbs nicely into the skin, and a little goes a long way. I NIVEAs

deep hydration and works especially well for very dry skin.
The formula feels rich and nourishing but still absorbs nicely without feeling greasy. After applying it, my skin feels soft, smooth, and comfortable for hours. I also love that it contains ingredients like glycerin, Pro-vitamin B5, and niacinamide to help repair and protect dry skin.

Works great
Size: 13.5 Ounce (Pack of 1)
Finally found a lotion cream that worked for my diabetic skin!! It’s not greasy and last a long time. I use it all over and made such a big difference.

Great Daily moisturizer
Size: 13.5 Ounce (Pack of 1)
Very light and neutral smell ( although I can understand that the scent may not be to everyone’s liking). The new formula with niacinamide adds a great benefit for your skin. Leaves the skin moisturized. Compared to CeraVe and Cetaphil intense moisturizers, those are much more heavy and longer lasting but overall I really like this product and will continue to use it as part of my daily moisturizer. I do wish NIVEA was more environmentally conscious.

The best!!
Size: 13.5 Ounce (Pack of 1)
Love this Nivea. And love that it’s in a tub and not a pump bottle so I can scoop out exactly how much I need and get every bit out at the end of every tub. I use this every day as soon as I get out of the shower. I lotion my entire body. It has made my skin baby soft smooth. It has also really helped with dry skin I had on my feet as well. Love it. I use my retinol and other skincare products on my face and neck and then I lotion my entire body right up to my chin. I don’t really use this on my face because I have other products for that but you could. It’s not greasy and absorbs well. Locks in moisture. And you get quite a bit for the money. I do wish Nivea’s skin firming lotion came in a tub like this too.
