If you already own an older Buffet bottle, compare its box with the current ingredient list before assuming every ingredient is unchanged: The Ordinary updates formulas, and ingredients can vary with purchase date and region.1

The displayed prices are US$40.60 on The Ordinary's Philippines storefront and €35.70 on its French storefront. Those are regional prices for the named serum, not evidence that one name represents a premium version. Choose by your local price and bottle size rather than treating Buffet and Multi Peptide + HA as different price tiers.12

What can you expect?

The serum targets dryness, fine lines and changes in firmness and elasticity. The Ordinary reports improvements in crow's feet, smoothness, texture, elasticity and firmness after eight weeks of consistent use in an independent study of 30 people. Expect modest cosmetic improvements, not a facelift with a dropper.23

The serum is an optional addition, not a replacement for moisturizer and sunscreen. Daily moisturizer and broad spectrum sunscreen with SPF 30 or higher are the starting point for care aimed at signs of aging. Moisturizer can immediately soften the appearance of some fine lines; most other products need at least six weeks, sometimes three months.34

How do you use it?

  1. 1Patch test first. Apply a small amount to clean skin on the upper forearm, keep the area dry and rinse after 24 hours. Do not use the serum if redness, burning, itching, blistering or irritation develops.
  2. 2Cleanse, then apply toner if you use one.
  3. 3Apply a few drops to the face morning and evening, using only unbroken skin.
  4. 4Follow with moisturizer.

The Ordinary lists direct acids, direct vitamin C, resveratrol and ferulic acid, salicylic acid, and its Multi Antioxidant Radiance Serum as combinations to avoid. Check those conflicts before adding the peptide serum to an existing routine.2

Who should be careful?

The Ordinary describes the serum as suitable for dry, oily and combination skin, but sensitive skin still needs a patch test. If irritation occurs, rinse it off, stop using it and consult a physician. Do not continue through stinging or burning. If consistent use leaves you dissatisfied with wrinkle improvement, a dermatologist can discuss other options.24
