Its formula features Niacinamide, Retinol, and Palmitoyl Tripeptide-1 in high positions, signalling meaningful concentrations.
Hydration Efficacy is another area of separation. Drunk Elephant A-Passioni Retinol Cream scores 8.7 here versus 6.7 for Biossance Copper Peptide (GHK-Cu) Rapid Plumping & Hydrating Serum with Hyaluronic Acid + Squalane. That difference comes down to how each formula is built — the ingredient list tells the story.
