The Ordinary Multi-Peptide + HA Serum (Buffet) review

In a market often dominated by exorbitant claims and equally exorbitant prices, The Ordinary has consistently championed transparency and affordability. Formerly known as “Buffet”, the newly renamed Multi-Peptide + HA Serum represents the brand’s most comprehensive approach to anti-aging. Rather than focusing on a single star ingredient, this serum offers a veritable feast of cutting-edge peptides and hydrating complexes designed to target multiple signs of aging simultaneously. It promises to improve skin elasticity, reduce the appearance of fine lines, and boost overall hydration in one elegant, water-based step. In this detailed review, we break down the complex peptide science, evaluate its layering potential, and see if this affordable powerhouse truly delivers luxury-level results.

The science behind the peptide complexes

Peptides are short chains of amino acids that act as the building blocks of proteins such as collagen, elastin, and keratin. The Multi-Peptide + HA Serum formulates an impressive 25.1% concentration of active peptide technologies, making it exceptionally potent.

The Ordinary Multi-Peptide + HA Serum (Buffet)

The formula relies heavily on the Matrixyl 3000 and Matrixyl synthe’6 complexes. These signal peptides trick the skin into believing that collagen has broken down, thereby stimulating the fibroblasts to produce new, healthy collagen and elastin, which plumps the skin and smooths static wrinkles from within. Additionally, it incorporates SYN-AKE and Argirelox—innovative neuropeptides that gently inhibit muscle contractions. Often referred to as “Botox in a bottle” (though far less dramatic), these complexes specifically target and soften dynamic expression lines around the forehead and eyes. To ensure these powerful actives are delivered in a deeply hydrating medium, the serum includes multiple molecular weights of Hyaluronic Acid, drawing moisture into various layers of the epidermis to provide an immediate surface-level plumping effect.


In-depth performance and routine integration

Applying the Multi-Peptide + HA Serum is a pleasant, straightforward experience. The serum boasts a slightly viscous, water-based texture that spreads easily. A few drops are sufficient to cover the entire face and neck. Because it is water-based, it should be applied after cleansing and toning but before any heavier oils or creams.

In terms of performance, the hydration benefits are instantaneous. Skin feels immediately quenched, soft, and visibly plumper. However, the true benefits of the peptide complexes require patience. Unlike exfoliating acids that offer overnight radiance, peptides operate on a structural level. With consistent, twice-daily application over the course of eight to twelve weeks, users generally observe a marked improvement in skin density and elasticity. Fine lines, particularly those caused by dehydration, appear significantly diminished, and the overall complexion looks firmer and more resilient. The only minor caveat is its layering compatibility; if applied too generously or combined with other thick serums, it can occasionally feel slightly tacky or pill under certain silicone-based primers or sunscreens.


Pros and cons of the serum

Pros

  • Outstanding value for money, offering a highly concentrated, advanced peptide blend at an accessible price.
  • Comprehensive formula targets multiple signs of aging, including static wrinkles and dynamic expression lines.
  • Lightweight, water-based texture that provides deep, immediate hydration via hyaluronic acid.
  • Improves overall skin elasticity and firmness with consistent, long-term application.

Cons

  • Can feel slightly tacky on the skin if too much product is applied or if layered improperly.
  • May pill when combined with certain heavy silicones or thick sunscreens.
  • Structural anti-aging results require consistent, long-term application; this is not a quick fix.

Ultimately, The Ordinary Multi-Peptide + HA Serum stands as a testament to the fact that effective, science-backed anti-aging skincare does not need to cost a fortune. By combining proven collagen-stimulating peptides with muscle-relaxing neuropeptides and deep hydration, it offers a beautifully formulated, preventative, and corrective treatment. For anyone looking to seriously upgrade their anti-aging routine without the luxury markup, this serum is an undisputed essential.
