Which peptide is right for you?

Start with the concern, not the ingredient

Most people buy peptides backward. They hear a peptide is good, buy it, and then hope it matches their skin. The better order is to name your main concern first, then choose the peptide built for that job. Below, each section is a concern. Find yours and follow the link to the deeper explainer.

One rule applies to all of them: peptides are gradual support ingredients. Give any pick eight to twelve weeks of consistent use before you judge it, and keep daily sunscreen in the routine no matter which one you choose.

For the look of firmness and fine lines

Best peptide: Matrixyl 3000. This is one of the most studied signal peptides for the appearance of firmer skin and softer fine lines. It nudges skin toward firmer-looking behavior over time rather than forcing a fast change, so it rewards patience and consistency.

Read the full breakdown on the Matrixyl 3000 page, or see it in the Collagen Peptide Stick.

For uneven tone and dark marks

Best peptide: Oligopeptide-68. If your concern is the look of uneven tone, post-blemish marks, or general dullness, a brightening peptide aimed at the pigment pathway is the cleaner play than a harsh acid. Oligopeptide-68 pairs well with niacinamide for tone support and is gentle enough for daily use.

More on the Oligopeptide-68 page, or in the Brightening Peptide Stick.

For redness and reactive skin

Best peptide: Palmitoyl Tripeptide-8. When skin is flushed, sensitized, or simply tired of strong actives, this is a peptide used for visible calm. It is the opposite of an aggressive ingredient, which is exactly why reactive skin tends to get along with it.

See the Palmitoyl Tripeptide-8 page, or the Barrier Repair Peptide Stick.

For barrier support and renewal

Best peptide: GHK-Cu, the copper peptide. If your skin feels compromised, rough, or just not resilient, GHK-Cu has a long research history around skin renewal and the look of a reinforced barrier. It is a strong choice for recovery nights and for skin that has been pushed too hard by other actives.

Details on the GHK-Cu copper peptides page, or in the Copper Peptides Stick.

For under-eye puffiness

Best peptide: Acetyl Tetrapeptide-5. The under-eye area is thin and easy to irritate, so it deserves a peptide chosen for it rather than a strong active borrowed from elsewhere. Acetyl Tetrapeptide-5 targets the appearance of puffiness, especially the morning fluid kind, and is comfortable for daily use.

See the Acetyl Tetrapeptide-5 page, or the Depuff Peptide Eye Stick.

For nighttime texture, gently

Best pick: our Retinyl-Peptide Complex. If you want texture support but free retinol is too much for your skin, this is the one place we use a retinoid, in the form of encapsulated retinal paired with smoothing peptides. It is the gentler nighttime route to refined-looking texture.

More on the Retinyl-Peptide Complex page, or in the Overnight Renewal Stick. For how retinoids and peptides compare, see peptides vs. retinol.

Can you use more than one?

Yes, and most people end up with two or three, because skin rarely has a single concern. Peptides are some of the most layer-friendly actives in skincare, so a typical setup might be a brightening or firming peptide in the morning and a barrier or renewal peptide at night.

If you would rather not decide alone

Our 2-question quiz does this matching for you. It asks what you want to change and recommends the stick and peptide built for it, with an alternative if you want a partner product. It takes about thirty seconds and it is the fastest way to skip the research.
