Moisturizing Sunscreen
Size: 2.82 Fl Oz (Pack of 1)
The grass-fed tallow base makes it deeply moisturizing—it feels like a nourishing balm. The PDRN complex is a nice bonus for repair.

Amazing, clean and natural ingredients!
Set name: Adult Tube - 3.4oz., Set name: Adult Tube - 3.4oz.
Literally the best sunscreen I have tried so far! Main ingredient is grass fed beef tallow which is what I’ve been looking for. I’m an outdoor/wedding photographer so I’m more susceptible to skin cancer due to genetics. Yesterday I used it all day for an outdoor wedding, reapplying every 2 hrs and this saved me so much!!! No white cast residue so I was applying quickly in between big moments and the formula is lightweight, no odor, goes on quick and smoothly and it’s not greasy! I have so much appreciation for the clean, natural ingredients

I really like this Grass-Fed Tallow Mineral Sunscreen. It feels natural on the skin and doesn’t cause irritation. The texture is smooth, easy to apply, and gives good sun protection. I also like that it uses mineral ingredients and doesn’t have a strong chemical smell. It leaves a slight white cast at first, but it blends in after a few minutes. Great option for people with sensitive skin
