You will not regret buying!!
Scent: Unscented, Size: 4 Ounce (Pack of 2)
I don't normally write product reviews but this soap truly deserves it. I had heard about beef tallow products as a carnivore dieter but hadn't paid too much attention to them until I found a huge mass on my thyroid. Suddenly, I'm looking at all the products that I use and am shocked that everything has endocrine disrupters like dyes and fragrances. This was the most natural soap I could find and what a huge turn around in my skin. I have always had certain areas that are habitually dry and even lotion would not 100% fix them. After using this soap for over 2 weeks, my skin is so smooth and almost has that glow you see in lotion commercials. I have not applied any lotion at all in the last 2 weeks and I'm softer than I have ever been. I even shaved with it and it was the smoothest shave I have ever had. I used to use conditioner to shave with and this soap is far superior. It is also far superior to the facial lotion soap I was using. My face isn't dry anymore and no more rebound oil. The people that I have told about this are immediately grossed out and think that the soap smells. There is an ever so slight hint of tallow but it does not last and once you start using the bar it isn't noticeable unless you sniff the bar itself. It does initially leave that sticky feeling that you get from Castille soap, which is strange when you're used to conventional beauty bars or body washes. But please don't quit using it! That sticky feeling is adding moisture and protection to your skin and once you towel off I promise you will not feel sticky. After a few weeks, I promise it won't feel weird anymore and you'll have the best skin of your life!! I'm sorry for the long review, but I am so grateful for this product. It is not only a beauty miracle but better for your whole body, no more toxic chemicals leaching through you skin. And people are not lying when they say this soap lasts. I use it twice a day and I still have a good sized bar left. Also, it really does not disintegrate like regular bar soaps. A few reviews mentioned it being expensive and my husband also commented on this when I bought it, but in my opinion it is extremely cost effective!! This is my rationale, it replaces the facial lotion wash, shaving conditioner, and the need for body lotion and it lasts a long time. My other reasoning is that the long term medical costs of using toxic products just doesn't seem worth it.

Cleared up my skin!
Scent: Unscented, Size: 4 Ounce (Pack of 2)
I have been using this soap for a little over a year. I was on accutane to cure really stubborn acne and when I got off my acne came back. I started using this paired with a beef tallow and honey moisturizer as my only skincare and it cleared up my skin so well. I love this soap and it is so natural and nontoxic. Amazing product.

Great Value for size
Scent: Unscented, Size: 4 Ounce (Pack of 2)
Great value for the size, has an almost milky scent which is quite nice, gentle on the skin, and clean ingredients. If you're looking for body soap without any chemicals, I highly recommend this product.

Truth
Scent: Unscented, Size: 4 Ounce (Pack of 2)
I have used this product for just 4 days now. This will be good and bad. A good all natural soap is not going to sud up like other soaps, I was shocked when I read some of the reviews and suds or the lack of suds seemed to be a big issue. This soap has very little suds. Another issue was smell. I do not notice any smell at all, the next time I order this product I would like to try the lemon for a little sent. This bar will last a long time, a little really gos along way. I do not notice any dryness but my skins feels tighter which makes me think it’s dry. I use my favorite body lotion and all is good. After the first use my skin was noticeably brighter. I had a pimple on my chin that was forming. I left the soap on my face for about 1 min. The next morning the pimple was nearly gone day two completely gone. I use a face cream called Just Tallow and combined with this soap it’s a perfect match. Tonight I put some soap on my feet and scrubbed them with a pumice stone and my feet are so soft right now. This is a good product and I will order again.
