The Science Behind Aseir Custom
We believe the best skincare starts with understanding what your skin actually needs, and formulating with ingredients it already recognises.
Our Formulation Philosophy
Every Aseir Custom product is built on a simple principle: your skin already knows how to repair and renew itself. It just needs the right raw materials. We formulate with ingredients that work with your body’s existing biology rather than overriding it with synthetic alternatives.
We use pharmaceutical-grade concentrations of active ingredients, manufactured to the highest purity standards. No water fillers, no synthetic fragrances, no unnecessary additives. If an ingredient doesn’t serve a clear purpose for your skin, it doesn’t belong in our formula.
GHK-Cu: The Copper Peptide
What Is GHK-Cu?
Copper Tripeptide-1GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper peptide found in human plasma, saliva, and urine. It was first identified in human blood in the 1970s and has since become one of the most extensively studied peptides in skincare science.
GHK-Cu is a signalling molecule. It communicates with your skin cells to support the natural processes your body already performs, including collagen and elastin production, antioxidant enzyme activity, and overall skin renewal. Its levels naturally decline with age, which is one reason skin changes over time.
Our formulations use GHK-Cu at concentrations up to 3%, which is one of the highest topical concentrations available. Every batch is manufactured to pharmaceutical-grade purity standards.
Carbon 60 (C60)
What Is C60?
BuckminsterfullereneCarbon 60 is a molecule composed of 60 carbon atoms arranged in a spherical structure, often called a “buckyball.” It was discovered in 1985, and the discovery earned the Nobel Prize in Chemistry in 1996.
C60 is one of the most powerful known antioxidants, with a unique ability to neutralise multiple free radicals without being consumed in the process. In our Auxano Grow V2 Hair Growth Formula, C60 works alongside GHK-Cu to address oxidative stress at the follicle level.
Grass-Fed Tallow: Ancestral Skincare
Why Tallow?
Biocompatible MoisturisationGrass-fed beef tallow has a fatty acid composition that closely mirrors the lipid profile of human sebum. Oleic acid, palmitic acid, and stearic acid are among the primary fats in both tallow and in the skin’s own moisture barrier.
This structural similarity means tallow integrates with the skin rather than sitting on the surface. It’s rich in fat-soluble vitamins A, D, E, and K in their most bioavailable forms.
Our Whipped Tallow Balm contains just two ingredients: 100% grass-fed tallow and natural vanilla bean extract. Nothing synthetic. Nothing your skin doesn’t recognise.
What We Don’t Do
We don’t make medical claims. We don’t use synthetic fragrance. We don’t add water fillers to increase volume. We don’t use parabens, phthalates, sulfates, or artificial preservatives. We don’t formulate based on trends.
Every Aseir Custom product exists because the science behind its active ingredients is well-documented, and the formulation delivers those ingredients in a way your skin can actually use.
