Learn what The Ordinary Multi-Peptide Serum does, which version fits your routine, how to use it, and what to expect from copper peptides in skincare.
The Ordinary Multi-Peptide Serum is a lightweight, water-based anti-aging serum built around lab-made peptides that support the skin's own collagen and elasticity over time. It is sold in several versions, including Multi-Peptide + HA Serum and Multi-Peptide + Copper Peptides 1%, plus targeted formulas for eyes, lashes, brows, and hair. It hydrates and smooths, but it is not a fast wrinkle remover, and any firming effect builds gradually with consistent use.
What the Formula Actually Does
Peptides are short chains of amino acids. In skincare, they behave more like messengers than building blocks: they signal the skin to keep doing the repair work it already does, which is why they are marketed around firmness and fine lines.
The Ordinary's version is a "buffet" style blend — several peptides plus hyaluronic acid and amino acids in a single bottle. In practice, that means one product covers hydration, surface smoothing, and long-term firmness support, which is why it is often recommended as an affordable first peptide product.
What it will not do is behave like a prescription retinoid or an in-office treatment. It also will not replace daily sunscreen, which remains the single most effective anti-aging step in any routine.
Which Version Is Which?
The most common confusion with this line is that the name refers to a family of products rather than one bottle. Here is how the main options compare.
| Product | Headline peptides | Best for | Texture |
|---|---|---|---|
| Multi-Peptide + HA Serum | Matrixyl 3000, Matrixyl synthe'6, SYN-AKE, Relistase, Argirelox | All-over facial firmness and hydration | Light, watery |
| Multi-Peptide + Copper Peptides 1% | The same blend plus 1% copper tripeptide-1 (GHK-Cu) | Mature or stressed skin, barrier support | Light blue, watery |
| Multi-Peptide Eye Serum | Peptide blend plus hyaluronic acid | Crow's feet, puffiness, under-eye area | Gel-like |
| Multi-Peptide Lash and Brow Serum | Myristoyl pentapeptide-17, biotinoyl tripeptide-1 | Lash and brow density, not the face | Thin liquid |
| Multi-Peptide Serum for Hair Density | Peptides plus caffeine and biotinoyl tripeptide-1 | Scalp and thinning at the part line | Light lotion |
Shoppers looking for a serum with copper peptide usually land on the 1% formula, which adds GHK-Cu, a copper-bound peptide studied for collagen signaling and barrier support. If your goal is a flexible daily hydrating product, the HA version is the easier one to layer.
A separate scalp formula sold as the ordinary multi-peptide serum for hair density is applied to the hairline rather than the face. It targets thinning at the part line and is not designed for facial skin.
Key Ingredients Worth Knowing
- Matrixyl 3000 — palmitoyl tripeptide-1 plus palmitoyl tetrapeptide-7, one of the most studied peptide combinations for fine lines.
- Matrixyl synthe'6 — palmitoyl tripeptide-38, aimed at the skin's surface matrix.
- SYN-AKE — a synthetic peptide modeled on a snake venom protein, used for the look of expression lines.
- Argirelox — acetyl hexapeptide-8 combined with a penetration enhancer, also used for dynamic lines.
- Copper tripeptide-1 (GHK-Cu) — present only in the 1% formula.
- Hyaluronic acid — pulls water into the upper layers of skin for immediate plumping.
Individual peptide concentrations are not published, and "1%" refers only to the copper peptide in that specific bottle, not to a total peptide load. That distinction matters when you compare labels across brands.
How to Use It in Your Routine
- Cleanse and apply to clean, dry skin.
- Use water-based serums first — this includes the ordinary multi peptide ha serum, which layers well under heavier creams.
- Apply a few drops to the face and neck and pat in. Keep it off the eyelids unless you are using the eye formula.
- Follow with moisturizer, then sunscreen in the morning.
- Use once or twice daily. Many people use the copper version at night.
For the eye area, the ordinary multi-peptide eye serum has a lighter gel texture made for the orbital bone, so it should be tapped on with a fingertip instead of rubbed in. If your concern is lashes or brows rather than skin, the lash and brow version is a separate product applied to the hair itself once daily.
What Results to Realistically Expect
Hydration and smoother texture can show up within days, mostly from the hyaluronic acid. Firmness and fine-line changes, if they occur, generally take 8 to 12 weeks of consistent use, and the difference is usually modest rather than dramatic.
Peptide results are cumulative, which means the support fades when you stop using the product. Consistency matters far more than stacking five different peptide serums at once, and more than most people expect.
Conflicts, Safety, and Who Should Skip It
- Copper peptides are commonly advised not to be used in the same routine as strong antioxidants like L-ascorbic acid (vitamin C) or direct acids, because the ingredients can interfere with each other. Separating them by time of day is the usual workaround.
- Patch test behind the ear for 24 hours, especially with the 1% copper formula.
- Stop using it if you develop persistent redness, stinging, or irritation.
- If you are pregnant, breastfeeding, or managing a skin condition, check with a healthcare professional before adding peptides to your routine.
These are cosmetic products, not drugs, and none of them are intended to treat or cure a medical condition.
How It Compares to Other Peptide Serums
At roughly $15 to $35 depending on the version, this line sits at the budget end of the peptide market. By comparison, the inkey list collagen peptide serum lands at a similar price with a simpler peptide profile, while PDRN-based options from Korean brands typically cost more.
The trade-off for the low price is texture and finish. The Ordinary's formulas are watery and fragrance-free, which suits oily and sensitive skin but can feel thin to anyone used to a richer serum. If you want the largest peptide blend for the least money, this line is hard to beat.
Frequently Asked Questions
What does The Ordinary Multi-Peptide Serum actually do?
It delivers a blend of lab-made peptides plus hyaluronic acid to support hydration, smoother texture, and the appearance of firmer skin over time. Peptides act as signaling ingredients rather than wrinkle removers, so results are gradual. It works best as a daily supporting step alongside sunscreen and moisturizer.
Can I use The Ordinary Multi-Peptide Serum with vitamin C?
The 1% copper peptide version is usually kept separate from vitamin C and direct acids, because copper peptides and strong antioxidants can interfere with each other. A common approach is to use vitamin C in the morning and the copper serum at night. The Multi-Peptide + HA Serum without copper is easier to layer.
How long does it take for The Ordinary Multi-Peptide Serum to work?
Hydration and a smoother surface can appear within days, mostly from the hyaluronic acid. Firmer-feeling skin and any change in fine lines typically take 8 to 12 weeks of consistent use. The effect fades if you stop using the product, so consistency matters more than quantity.
