Great Value for a Good Moisturizer (5- Stars)
Size: 3 Fl Oz (Pack of 1)
This moisturizer contains nothing fancy — and that’s the whole point. The ingredients are few but effective, with several ceramides and hyaluronic acid for deep and long-lasting hydration. Best of all, it contains no silicones or parabens. Because it’s noncomedogenic, it doesn’t cause breakouts from clogged pores. Since I have sensitive skin, all of the above are critical for my skin care routine. It’s about as simple and as effective as a cream can get. Because of that, it doesn’t contains any sunscreen, retinol, or other anti-wrinkle components.

Excellent facial moisturizer
Size: 3 Fl Oz (Pack of 1)
Very gentle, lightweight, absorbs well without feeling greasy or heavy. Perfect to use after Fraxel laser treatment. I also like it is fragrance free and really good on sensitive skin.

Highly recommend! But still irritates sensitive skin
Size: 3 Fl Oz (Pack of 1)
Exceeded my expectations! Lightweight, yet has a bit of occlusiveness (which I needed)! Hydrates my skin really well! Like the subtle smell of it also! It tried other popular ones (with almost no occlusive components) as La roche and ordinry, but they were too dry for me. I needed the moisture to be locked in plus restore my skin barrier also. So so far vanicream was so good! My skin type: dry, sensitive, highly irritating. Ps I would have to try another brand after finishing this one. Irritates my skin. It’s not for sensitive skin, unfortunately

Inexpensive and Effective
Size: 3 Fl Oz (Pack of 1), Size: 3 Fl Oz (Pack of 1)
I’ve struggled with dry sensitive skin and eczema my entire life and this is now my ride or die facial moisturizer. It’s so much less expensive than luxury brands that I have tried and works better. It absorbs so well, leaves no residue, and a small amount goes a long way. I will say, if you have an active eczema flare it can sting a tiiiiny bit but that’s an eczema thing. It causes zero irritation or inflammation there’s just some sensation as it goes on. Vanicream as a brand in general is soooo eczema friendly. Life changing.

This stuff works nicely
Size: 3 Fl Oz (Pack of 1)
So I don't typically leave reviews, but I feel like this lotion has been fantastic to me. I typically don't use lotion because I hate the feel, but my face really needed it. I have dry/oily skin. My skin gets gross and flaky, yet it's pretty oily. I've always dealt with it. I decided to go ahead and buy this stuff because I couldn't take my dry skin. It helps soooo much and you barely need any. I use a dime sized amount and really focus on my problem areas. It lasts all day, not too thick and not too watery. Not greasy at all for me and soaks in very nicely. Again, it lasts all day and I don't need touch ups, even on bad skin days. I don't ever break out and it's never clogged my pores, but to be fair I've never really had skin that's broken out much before. The one thing I did notice, before using this stuff I started noticing more fine lines around my eyes/forehead. I've been using this stuff for about a year and you can barely see them anymore. I have haven't changed my diet, it's pretty atrocious honestly, so I really feel this lotion has worked wonders on its own. Also I still have a decent amount left in the bottle and I bought it almost a year ago. I'm going to try their body lotion next. Hope this helps, or at least give it a whirl!
