Love this soap. Perfect for removing make up and oils before bed. No ever powering scent and you can feel the clean after using. Great value for the money

Great first impression!
Scent: Unscented
This soap was delivered last night, so I used it first thing this morning. So far, I am very satisfied. It has almost no odor—which I like. It created a good lather and left my face and body feeling soft and clean, but not dry. The natural ingredients mean it’s actually good for my skin! It seems to be a great value. The only improvement I can suggest is to make the edges a little softer (more rounded) because it’s quite square to be rubbing my underarms (and other delicate areas). If new details are warranted, I’ll edit this review

Perfect for dry face or body
Scent: Lavender, Size: 2 Fl Oz (Pack of 1)
Love this tallow balm. I use it nightly after my serums and also mix with my foundation so it glides on my dry skin and it looks wonderful. A tiny bit goes a long way. The lavender is a light scent and smells so good. My skin has zero sensitivity to this and in the morning my skin looks great and feels so soft.will be buying mote of this . Excellent for dry skin.

This balm is Magical!
Scent: Vanilla, Size: 2 Fl Oz (Pack of 1)
This product was a life saver! After using the same face moisturizer for years, I suddenly became allergic to it. Overnight my face became swollen, red, sores that oozed, it was disgusting, embarrassing, and painful. I was diagnosed and treated for impetigo- which I knew was not the cause. But I didn’t know the cause until it cleared up and I went back to the old moisturizer because I was sure it couldn’t be that after years of use. But it was and I had another outbreak. So I researched an American made product and found this balm. It is magic! Within a week of using it the symptoms were gone! I love the scent, the protection it provides, and just how very soothing it is on my face. It is the right thickness to keep my face from dryness all day long. I love the feel of adding a glow to my skin with a rich oil that is pure and allergy free. I’m on my second jar and will be a loyal customer from here on out!
