Feb 2026 order German made
Size: 8.4 Ounce (Pack of 1)
Purchased in Feb 2026 and I can confirm the product I purchased is legit from Germany. It's a little tricky to sort through and find the German made ones and I'm unsure if other countries have the same ingredients, I know the US ones are made in Mexico and the ingredients are NOT the same and yes it makes a huge difference. This is thick, the smell isn't overpowering at all and it sinks right in. Great for dry winter skin and keeping hands and other body parts super soft. I slather this on my face before bed every night and my skin is glowing. I have used la mer (and everything in between) and I think this blows it away. Phenomenal product. Excellent price. Love it. Highly recommend.

Deceptive Listing but Good Product
Size: 8.4 Ounce (Pack of 1)
This is not the German version as it have Petrolatum. Based on ingredients it is the Mexican/American version. That being said, it's great and I enjoy how moisturizing it is as a body cream (though it causes acne if I use it on my face) and will purchase again (though not from this listing as it is more expensive than the regular listings for the same item).

Nivea
Size: 8.4 Ounce (Pack of 1)
NIVEA is a classic for a reason! This cream is super moisturizing and perfect for dry or rough skin. It feels rich and nourishing without irritating my skin. I love using it at night, and I wake up with my skin feeling soft and smooth. It’s affordable, effective, and a must-have in my skincare routine. I highly recommend it!

Tretinoin Users- THIS is for YOU!
Size: 8.4 Ounce (Pack of 1)
I used this when I was younger on very chapped hands. I'm happy to have rediscovered this product for my face as an adult! For anyone using tretinoin, this is THE moisturizer for YOU!!!!! Not too much of a scent, thick product that absorbs well, and it's the best for the bathroom counter.
