Favorite in my routine. I love Vaseline lotions and this is a perfect last step to my neck and hands every morning. Gives a boost of hydration and a nice glow to my neck. I think this is keeping me from crepey neck skin. Gotta fight that ladies! I use this several times a day and have it to all my friends for Xmas.

Something is different

Size: 0.42 Fl Oz (Pack of 6)

Product seems okay, but something has changed about it. Perhaps a different ingredient. Something different about the smell and texture. Still smells good, not greesy, and absorbs into skin like the past products I have purchased, but definitely something has changed.
