Wow, Dove really outdid themselves. Great product.
Scent: Fragranced, Size: 30.6 Fl Oz (Pack of 1)
Wow, what a difference what a difference Amazon basic body wash is what I was using before to be honest and it used to be very good. I don’t know if they changed the formula but that formula now it doesn’t lather up. You have to use half the bottle to get it to lather up this one lathers up amazingly well and you only need a few pushes. As a guy, I love it. We have dry skin too, just like anybody else so between moisturizer and lather , the scent the skin protection the skin softeners the whole thing it’s great. And you get a lot of of it too, which is awesome so overall at least to me a great value for the money

Perfect for Sensitive Skin Without Feeling Heavy
Size: 3 Fl Oz (Pack of 1)
I have very sensitive skin and finding a facial moisturizer that hydrates well without causing irritation can be a challenge. This one has been fantastic. It feels lightweight going on but still gives enough moisture that my skin stays soft and comfortable all day. No strong fragrance, no burning, no breakouts, just simple and effective skincare. I also really like that it layers well under makeup and doesn’t leave my face feeling greasy or sticky. The ceramides and hyaluronic acid make my skin feel healthier and more balanced overall. Vanicream continues to be one of the few brands my skin consistently tolerates well. I’ve already repurchased this and will keep using it.

Good for sensitive skin, zero fragrance, leaves skin soft and moisturized!
Size: 3 Fl Oz (Pack of 1)
I got this to go along with my Vanicream sensitive skin cleanser, and I'm very happy with it! It is a little more liquidy than cream-like, but it absorbs into skin well and leaves it feeling soft and moisturized. Great for sensitive skin and completely free of fragrance, with a shorter ingredient list that gives me more peace of mind. Very pleased with this, try it!
