Scent: Unscented-4.23OZ
I fell in love with this cream. It leaves my skin soft, pleasantly scented, and deeply hydrated. I use it all over my body—especially on my arms, where I suffer from severe dryness—and it is helping me with my "chicken skin." The only downside is that I can't use it on my face, as the skin in that area is very oily and it causes me to break out. But overall, I definitely really liked this cream.

I love the moisture 😍
Scent: Unscented-4.23OZ
I’ve been using this Tallow Honey Balm for a little while now and I’m really impressed with how moisturizing it is. My skin feels soft, smooth, and hydrated for hours after applying. I also like that it’s made with natural ingredients like grass-fed beef tallow and raw honey, which feels gentle on sensitive skin.
The balm has a rich texture, so a little goes a long way. It works great on dry areas like elbows, hands, and face. The only reason I’m giving 4 stars instead of 5 is because it can feel a bit greasy if too much is applied. Other than that, it’s a solid product and definitely worth trying if you struggle with dry skin

Game changer for me
Scent: Unscented-4.23OZ
I don't review stuff... I just don't. But this is the best face cream I've ever used. Fine lines are going away. I'm a senior and I've tried oils, creams, sooo many face products. This is a game changer for me. My skin just drinks it up. I don't expect to look 20 again, I just want to look my best for my age. I've been using this product 2 weeks. I think my skin is looking like it did 10 years ago. I'll take it! It absorbs great. My skin does not look or feel oily like so many other products made my skin. Can't express how much I love this stuff!
