Tallow meets PDRN
Ultra Renew PDRN Serum is built on the base of our Pure Balance Tallow Serum, a customer favorite: grass-fed tallow, hyaluronic acid, niacinamide and green tea. We added Marine Cellular Complex™, a salmon-derived ingredient that carries PDRN along with naturally occurring peptides and proteins. A tried-and-true base, meeting skincare's hottest ingredient.
Background on the ingredient: in July 2026, PLOS ONE published a randomized, double-blind, split-face study comparing a 0.1% PDRN eye cream with 0.1% retinol in 31 women over 28 days. The authors reported larger improvements on the PDRN side. It's one study, of a different PDRN material, around the eyes. We share it as context for the ingredient, not as a claim about our serum.
