Works great, smells good, and does not leave you feeling slimy or greasy.
Size: 20.3 Fl Oz (Pack of 3)
This stuff is the best for men who do not like feeling greasy when they use lotion. It works good for healing and preventing cracking and drying of skin, but it may have to be applied multiple times a day for people with very dry skin.

Great product at a great price
Size: 20.3 Fl Oz (Pack of 3)
Great price for a product that I have used and liked for years. Lotion dries quickly and has nice masculine scent. In addition to moisturizing my hands, I also use it for aftershave lotion on my face.

Lot of Waste but Great Lotion
Size: 20.3 Fl Oz (Pack of 3), Size: 20.3 Fl Oz (Pack of 3)
I have eczema and have tried dozens of lotions, and this one works great for me. The reason I have settled on this one is that it works great for my skin, not greasy, and I like the smell, not being too strong and feminine like most lotions.
My only complaint is that there is a ton of leftover lotion in the bottom that the pump can't reach. I have the cut the bottle open each time so I don't waste it.

Best lotion I can find
Size: 20.3 Fl Oz (Pack of 3)
Lubriderm discontinued the perfect men’s 3-in-1 lotion and it’s no longer available. After trying multiple substitutions, I found this. Mind you, I have scent and skin issues and NORMALLY buy unscented. I was concerned that this would cause issues and quite the opposite happened. I’ve discovered it works BETTER than the previously mention “perfect product” and though it is scented, the scent is pleasurable and super quick to fade, not at all overpowering and truly quite enjoyable. A fresh boost without causing me ANY problems. I am so pleased with this Vaseline product that I’m actually better now about keeping my skin hydrated, and, find myself humming while dressing post shower and application (I apply at the conclusion of my shower while still in the shower. That’s new - I hadn’t noticed or thought about it until my spouse asked me “why the good mood in the mornings lately.” Subconscious I guess but it’s a great way to start long days feeling clean and confident, rather than just washed, rinsed and repeat.
