These two serums take different paths to a similar destination. Both formulas include solid hydrating ingredients, and the overall scores reflect that — the gap here is genuinely slim.
Hydration Efficacy is another area of separation. Murad Mini Vitamin C Glycolic Brightening Serum scores 9.7 here versus 8.6 for The Ordinary Multi-Peptide + Hyaluronic Acid Serum for Firmness and Elasticity. That difference comes down to how each formula is built — the ingredient list tells the story.
The Ordinary Multi-Peptide + Hyaluronic Acid Serum for Firmness and Elasticity brings Acetyl Hexapeptide-8, Pentapeptide-18, and Palmitoyl Tripeptide-1 as actives, while murad Mini Vitamin C Glycolic Brightening Serum relies on Glycolic Acid, Ascorbic Acid, and Inositol. Both approaches have merit, but the positioning and supporting ingredients make the difference.
Both sit in the mid-range bracket, so value comes down to formulation quality. The Ordinary Multi-Peptide + Hyaluronic Acid Serum for Firmness and Elasticity gets the nod here with its 8.8 overall score — you're getting more for a similar outlay.
