- Palmitoyl tetrapeptide-7 is a four-amino-acid peptide attached to a fatty acid.
- It's used to calm the look of redness and support skin's structure.
- It's a helpful partner for sensitive or easily flushed skin.
What it is
A tetrapeptide is four amino acids long. Like palmitoyl tripeptide-5, it carries a palmitoyl group so it blends well into skincare formulas.
What it does
It's included in formulas to help calm the look of redness and to support the skin's structure, so skin looks more even and resilient over time.
Why it matters in an anti-aging serum
Anti-aging actives can sometimes leave skin feeling stressed. Including a calming peptide helps keep the whole formula comfortable, which is part of why DOSE suits most skin types. See copper peptides for sensitive skin.
Good to know
- It's often paired with palmitoyl tripeptide-1 in other products; DOSE pairs it with GHK-Cu and five other peptides.
- Redness can have many causes. If yours is persistent, see a dermatologist.
