Best Beef Tallow Cream I’ve Tried
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
Exactly what i was looking for, some of the beef tallow creams have a weird consistency which i don’t love wearing during the day. This cream is perfect for day and night. smells very good, application is perfect not greasy, moisturizing, soft. I love it! 10/10,
will be buying again 💗

Order it! Its great
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
I love the texture! Its silky smooth and light on the skin, no weird smell, very moisturizing. Ive used one of the containers for most of my pregnancy to keep the skin on my belly and hips moisturized. I add a few drops of organic frankincense to a nickel-sized amount of this balm and mix it together in my hands before applying. I use a clean q-tip to scoop out the tallow balm as needed too to be sure the rest in the jar stays clean, rather than using my washed fingers, to reduce accidentally contaminating the rest of it somehow. My skin has stayed so healthy thanks to this product. It reduces the itchiness of my expanding skin from the baby growing in my belly, and i think its made a positive difference in preventing stretch marks by keeping my skin hydrated as i use it almost daily and after every shower. I just got my second jar in the mail to use for this last month of my pregnancy, and I will probably use it for my baby when hes born too.
I also love that it comes in nice packaging, with a thank you note, very minimal plastic, and classy label. I dont think the jar is plastic either which i LOVE (pretty sure its glass container?) Thank you to the creators of this product. I kind of wish i could get it in a glass dispenser like lotion but i really dont care at the end of the day. Its amazing. You should try it.

Smells nice and light
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
Nice and creamy. Feels silky. Unfortunately, it does not help my knuckles very much. But I would buy it again because it is a good cream.

Excelentt
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1), Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
This product is really good, I researched it because it is the closest to human skin, and that was what it did help me repair my skin that was injured after an allergy of more than two months. I felt that I had lost the elasticity and shape of my skin, this fat stuck to me and made me feel safe again.

Will repurchase
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
At 56 years old my skin is pretty dry but this was still a little to heavy for a face cream-- but usable in a pinch. What it is PERFECT for is for your hands before you go to sleep at night. You know you're going to touch your face and pillow during the night so heavily fragranced creams aren't good at all. This is thick enough to make your hands and cuticles feel great but gentle enough not to cause problems if transferred onto your face.
