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.

Dermatologist recommended it!
Size: 1.3 Ounce (Pack of 1)
This is my 11th order of this product. I originally started using it a few years ago when my dermatologist recommended it during a period of hormonal acne. I’ve been using it ever since. I have very sensitive skin that usually reacts to almost everything, either with redness or breakouts, but I can use this cream comfortably without any issues. It is very gentle, deeply hydrating, and has become a permanent part of my skincare routine. It is definitely worth the price. Even a small amount provides excellent hydration and it lasts a long time. I also love that it has a natural ingredients and is fragrance-free.
