About Multi-Peptide + Copper Peptides 1% Serum

Overview

Multi-Peptide + Copper Peptides 1% Serum is a lightweight serum from The Ordinary, a brand based in Canada. The formula is built mainly around hydration and firmness signalling. The ingredient list runs to 49 ingredients, each broken down in full below.

Texture and finish

By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Hydration is handled by Glycerin, Sodium Hyaluronate Crosspolymer and Sodium Hyaluronate, humectants that pull water into the upper layers of skin rather than sealing it there.

What the formula does

Hydration: Very high. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Glycerin, Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate and Trehalose.

Firmness signalling: High. Peptides and growth factors that signal for collagen support, and here that comes from Copper Tripeptide-1, Acetyl Hexapeptide-8, Pentapeptide-18 and Palmitoyl Tripeptide-1.

Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Allantoin, Sodium Benzoate, Acetylarginyltryptophyl Diphenylglycine and Sodium Hyaluronate Crosspolymer.

Who it suits

On richness alone it suits Balanced skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.

What it does not target

The formula contributes little or nothing on barrier support, antioxidant protection and oil control. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.

What is not in it

Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.

Where it fits in a routine

It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.

This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.

Safety and suitability

Flags to check, not verdicts. None of this is medical advice — if you are pregnant, breastfeeding or treating a skin condition, ask a doctor.

Pregnancy and breastfeeding
Nothing in this formula is on the standard pregnancy-caution list. That is not clearance — ask your doctor about anything you use daily.
Fungal acne (malassezia)
1 ingredient could feed malassezia: Polysorbate 20. That is about the yeast's food supply, not a prediction that you will break out.
Sensitive and reactive skin
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
