Sweet, Clean Product! Perfect Under Makeup
Size: 4.2 Fl Oz (Pack of 1)
I am so impressed with this ELBBUB Whipped Tallow Cream. It is a sweet, clean product that keeps my face deeply hydrated all day without feeling sticky at all. I mostly use it as a daytime face cream under my makeup, and it creates a perfect, smooth base. It has helped my skin routine so much. Highly recommend!

Lovely product, low ROI
Size: 4.2 Fl Oz (Pack of 1)
The cream is lovely, not greasy, low odor, and beautifully hydrating. However, being quite the frugal customer, I cannot, in good conscientious, pay the cost per ounce.

Quality tallow in a giant container for an amazing price that doesn't bother my severe allergies!
Scent: Honey & Sweet Orange, Size: 5 Ounce (Pack of 1)
I have been using this product for 3 months and I love it! It is a thick consistency, like you would expect good quality tallow. It feels great on your skin and absorbs fairly quickly. It is a large size jar for the price, I still have over half left and I have used it on my neck and hands as well... sometimes on my legs. I am allergic to artificial fragrance, and this tallow does not bother me. The scent is pleasant, with a slight after-smell of tallow, but it is not unappealing. It is very moisturizing for many parts of the body, but I especially like it for my face and neck. My skin truly has a better glow and tone after using the product for a few months. I can't wait to see how great it will feel at the end of the jar!

Great value for the size. Easy to apply and absorbs quickly wherever you apply it. Does not leave any oily residue and it smells fragrant. Moisturizes and works quickly. Skin feels instantly smooth.
