Great moisturizer
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
This is a great product! The consistency is thick, but not heavy. No overwhelming fragrance. Applies easily and is absorbed quickly. Would definitely purchase again.

NO REGRETS NO FRETS 🙂
Size: 2 Ounce (Pack of 1), Color: Tallow
Love it. Nothing bad. Soft, creamy, absorbs amazingly well, no odor, does wonders for back of hands from frequent hand washing, can fill a crack in skin with the tallow to heal a dryness related wound. Wash hands dry and the warm water and some soaps can strip skin oil and use this tallow to seal and/or replace moisture in your hands! No greasy issues. Truly a lifetime pick and my jar has easily another month usage and had it so far at least two months. Just a dab on back of palms and rub and work up on forearm and elbow. You will not be disappointed using it. I keep near the sink to remind me 🙂

My new favorite moisturizer
Size: 2 Ounce (Pack of 1), Color: Tallow, Size: 2 Ounce (Pack of 1), Color: Tallow
This is the best moisturizer I’ve ever used on my hands. I struggle with dry hands in the winter from the cold and constant handwashing, so I’m always having to put moisturizer on to combat the dryness. My fiancé had started using beef tallow on his face (another more expensive brand) and was raving about it so I went searching on Amazon to get my own bottle. I chose this one based on the ingredients and the good reviews, as well as the price point. I love the way it melts into your hands leaving them silky smooth with no residue, greasiness, or stickiness. The reason that I deducted one star was because I felt the advertisement on Amazon was misleading. If you read the headline it makes it sound like the product has all organic ingredients. When I read the ingredient list once I received the product, the only ingredient that was listed as organic in the formula was the beeswax. I still love the product and I already bought another bottle, but I thought it was worth mentioning as I know that using 100% organic products is important to some people. I still highly recommend this product based on its effectiveness.

My skin feels nourished and radiant ✨
Size: 2 Ounce (Pack of 1), Color: Tallow
I’ve been using this balm for a little while now, and the difference is subtle but real. The texture is incredibly smooth and melts easily into my skin without feeling greasy. I can tell it’s made with really high-quality ingredients because it absorbs beautifully and leaves my skin feeling nourished immediately. Since I started using it, the areas that usually feel dry—my hands and the sides of my face—are softer and more supple. Even the little cracks and rough patches have improved, and my skin looks and feels renewed and radiant. It’s not an overnight transformation, but it’s a steady, noticeable change that makes my skin feel healthy and cared for. What I love most is how it strengthens my skin barrier. My skin feels more resilient and comfortable throughout the day, even in dry or cold weather. It’s like it quietly restores balance and keeps my skin happy without any heaviness or stickiness. Using this balm has made my daily skincare feel a little more nurturing and confident—my skin looks smoother, softer, and truly glowing 🐝💛
