The Ordinary Multi-Peptide + Hyaluronic Acid Serum, 1 fl oz — Anti-Aging for Crow's Feet, Firming & Hydration

The Ordinary Multi-Peptide + Hyaluronic Acid is a concentrated peptide serum designed to improve the look of crow's feet while supporting skin elasticity, firmness, and hydration.

This lightweight, water-based serum combines multiple peptide technologies, hyaluronic acid complexes, amino acids, and bio-derivatives to address several early signs of aging in one formula. Formerly called “Buffet,” the product blends established peptide actives (including SYN™-AKE, Matrixyl™ synthe'6™, Matrixyl™ 3000, and ARGIRELOX™) with multi-weight hyaluronic acid to hydrate and help refine skin texture. Results reported in controlled studies showed improvements in crow’s feet appearance, surface smoothness, and perceived firmness over an eight-week period when used consistently.

How quickly can I expect to see improvements around crow’s feet?

Visible reductions in the appearance of crow’s feet were reported in an eight-week study, but individual timelines vary based on skin type and routine consistency. Use twice daily as directed and combine with sun protection during the day for best visible outcomes.

• Clinical testing noted measurable changes at eight weeks.
• Consistent morning and evening application increases likelihood of results.
• Layer with SPF in daytime to protect progress from UV damage.

What key ingredients make this serum effective for texture and elasticity?

The formula unites four peptide technologies with multiple molecular weights of hyaluronic acid and skin-friendly amino acids. Peptides help target signs of aging like loss of firmness and lines, while hyaluronic complexes attract and retain moisture to plump surface texture.

• Peptide blend: SYN™-AKE, Matrixyl™ synthe'6™, Matrixyl™ 3000, ARGIRELOX™ (trademark owners noted)
• Multiple hyaluronic acid complexes for layered hydration
• Amino acids and bio-derivatives to support skin feel and resilience

How should I add this serum into my skincare routine?

Apply to cleansed skin before oils or heavier creams, both morning and evening. A few drops are sufficient—pat gently where you want to target fine lines and areas that need more lift or hydration.

• Use after toners and water-based treatments, before thicker moisturizers.
• Start with a patch test if you have sensitive skin; adjust frequency as needed.
• For daytime, follow with broad-spectrum sunscreen to maintain results.

Is this serum suitable for all skin types and sensitive skin?

The lightweight, water-based texture lifts comfortably across most skin types, including normal, combination, and oily skin. Those with reactive skin should patch-test products containing active peptides and multiple ingredients; discontinue if irritation occurs.

• Formulated to layer with other treatments rather than replace them.
• Non-greasy finish works well under makeup and sunscreen.
• Patch testing recommended for very sensitive complexions.

Who is this for: People noticing early signs of aging—like fine lines at the outer eye, softer skin texture, or reduced firmness—who want a multi-targeted, hydrating peptide serum. It suits users seeking a single, science-forward step to add to an existing routine, provided they follow with sun protection during daytime use. Those with specific skin conditions should consult a dermatologist before introducing potent active blends.
