The Ordinary Multi-Peptide + Hyaluronic Acid Serum 1 fl oz — Anti-Aging, Hydrating Peptide Complex

The Ordinary Multi-Peptide + Hyaluronic Acid is a concentrated anti‑aging serum that combines four peptide technologies with hyaluronic acid complexes to help improve the appearance of crow’s feet, skin elasticity, and firmness.

This lightweight, water‑based serum from The Ordinary layers easily into morning or evening routines and is designed to target several early visible signs of aging at once. Its formula blends peptide complexes (including SYN™‑AKE, Matrixyl™ synthe'6™, Matrixyl™ 3000, and ARGIRELOX™) with multi‑weight hyaluronic acids and amino acids to hydrate, support skin texture, and promote a smoother look over time. Clinical testing on a small group showed reduced appearance of crow’s feet after consistent use for eight weeks.

How quickly will I see changes around crow’s feet?

Visible reductions in fine lines and crow’s feet were reported in an eight‑week independent study, but individual results can vary depending on skin type and routine consistency. Use twice daily for best chances of visible improvement.

• Independent study: reduced crow’s feet appearance after eight weeks with routine use.
• Apply a few drops to clean, dry skin around the eye area, avoiding direct contact with eyes.
• Combine with sunscreen in daytime routines to protect improvements from UV exposure.

What ingredients make this serum effective for firmness and elasticity?

The formula mixes multiple peptide technologies that signal skin’s repair and resilience mechanisms with hyaluronic acid complexes that attract and retain moisture. Amino acids and bio‑derivatives further support the skin’s feel and texture.

• Four peptide technologies (SYN™‑AKE, Matrixyl™ synthe'6™, Matrixyl™ 3000, ARGIRELOX™) to target multiple aging markers.
• Multi‑weight hyaluronic acids for immediate and longer lasting hydration.
• Amino acids and bio‑derivatives to support skin’s surface texture and suppleness.

How should I add this serum to my daily skincare routine?

Apply after cleansing and any watery serums, but before heavier creams and oils. A small pump or two of product spreads easily; a little goes a long way. If you use active treatments like retinoids, monitor skin sensitivity and introduce the serum gradually.

• Use morning and/or evening on clean, dry skin for best results.
• Follow with moisturizer and sunscreen during the day.
• Patch test when combining with strong actives and reduce frequency if irritation occurs.

Is this product suitable for sensitive or combination skin?

The Ordinary’s Multi‑Peptide + HA Serum is water‑based and free of heavy oils, making it suitable for many skin types, including combination skin. Sensitive skin users should patch test first because concentrated peptides and actives can occasionally cause irritation.

• Lightweight, non‑greasy texture works well under moisturizers and makeup.
• No thick oils, so it layers cleanly for oily or combination complexions.
• Patch testing recommended for very reactive skin due to active peptide blend.

Who is this for? This serum is aimed at people noticing early to moderate signs of aging—fine lines, initial crow’s feet, and loss of elasticity—who want a single, multi‑targeted product to add to their routine. It’s suitable for those who prefer science‑forward formulations with peptides and hyaluronic acid, and for anyone building a preventive or corrective anti‑aging regimen while continuing sun protection and gentle daily care.
