Good Molecules Super Peptide Serum

What is it?
Top things to know about Good Molecules Super Peptide Serum
- Good Molecules Super Peptide Serum is a thin, fragrance-free peptide serum, around $12 to $14 online. It is a light water layer, not a treatment — no retinoid, no acid, no vitamin C, and no real moisturizing.
- The bottle names three peptides: acetyl hexapeptide-8, sold as Argireline, acetyl octapeptide-3, and copper tripeptide-1. All three sit at the bottom of the list, after the preservatives. Preservatives are used below 1 percent, so anything after them is present at less than that. The rest is water, propanediol and glycerin.
All three peptides sit after the preservatives, and preservatives are used below 1%, so the doses here are far under what these peptides are marketed on. It is gentle, and a cheap way to find out whether peptides suit your skin. Buy it for that. For wrinkles, use a retinoid.

Skin fit
Is it right for your skin?
Sensitive Skin
Peptides are short chains of amino acids, the same building blocks skin uses itself. They do not exfoliate, acidify or speed up turnover, which makes them one of the few active categories that almost never stings. A cheap way to find out whether your skin tolerates them.
Normal Skin
If you have no particular complaint and want a light layer under moisturizer, this will not cause problems. Just be clear that the peptides sit below the preservatives, so the amounts are trace.
Oily Skin
Watery, with no film at all, so nothing here reads as grease by midday. The same thinness means almost no hydration, so you still need a moisturizer over it.
Texture
What it feels like on skin.
Serum
A thin, watery serum, closer to a toner than a serum. It absorbs instantly and leaves nothing behind, which is pleasant and also tells you how little is in it. There is very little hydration, so it lacks the fallback benefit richer peptide serums have. Fragrance-free, does not sting, layers under anything without pilling.
Alternatives
If this isn’t the right product for you
The Ordinary Buffet
About $17, with all seven peptide technologies at positions four to ten instead of below the preservatives, plus a good hydrating base. A few dollars buys a real dose.
Cosrx Peptide Serum
Around $20 for 150 ml, fragrance-free, with niacinamide sixth on the list. Niacinamide has far better evidence than any peptide, and the volume is exceptional.
The Inkey List Collagen Peptide Serum
Cheap, gentle, fragrance-free, with its peptides after the preservative too. It hydrates better, but there is no collagen in it despite the name.

The base the other ingredients are dissolved in. Most of it evaporates soon after the product goes on.
A small humectant. It moves into the outer layer of skin and holds water there.
A thickener that keeps the texture even.
Helps the preservative work and softens the feel of the product.
A form of hyaluronic acid. Its molecule is large, so it stays on the surface and holds water there.
Vitamin E, an antioxidant. Here it mainly keeps the oils in the product from going rancid.
How to use it

How to apply it
- How muchA few drops on clean skin, patted in rather than rubbed.
What to pair it with
- LayeringEarly in the routine, before heavier serums and moisturizer. Always follow with a moisturizer.
What to expect
- What to expectHonestly, very little you can see. Peptide evidence is thin even at study doses, and these peptides sit below the preservatives. Judge it on whether your skin tolerates peptides, not on lines. It should not irritate.
