What is in the CosRx 6 Peptide Skin Booster?
As the name says, it is built around six peptides (including copper tripeptide 1, acetyl hexapeptide 8 and palmitoyl tripeptide 8), plus niacinamide, hyaluronic acid and amino acids. Peptides are messenger ingredients loved for supporting the look of firmer, smoother, more even skin. It is a lightweight, well priced daily serum.
The one thing to know: it is a peptide serum. It does not contain PDRN or salmon DNA, which is a different family of ingredient entirely.
Peptides vs salmon DNA PDRN: they do different jobs
This is why the comparison matters. Peptides and PDRN are not competitors, they are partners:
- Peptides are prized for supporting the look of firmness and smoother texture over time.
- Salmon DNA PDRN is a water loving molecule loved for deep, cushioned hydration and a visibly plumped, dewy, age defying finish, and it suits reactive, easily upset skin beautifully.
A peptide only serum gives you one side. A salmon DNA skin booster that also carries peptides gives you the peptide benefit and the PDRN plumping and hydration in one step. That is the formula difference, and it matters more than any single headline ingredient.

Frequently asked questions
Does the CosRx 6 Peptide Skin Booster contain PDRN or salmon DNA?
No. It is a peptide serum with niacinamide and hyaluronic acid. It does not contain PDRN or salmon DNA. For both peptides and PDRN in one step, choose a salmon DNA multi peptide skin booster.
Is a salmon DNA skin booster better than a peptide serum?
They do different jobs. Peptides support the look of firmness and texture, while salmon DNA PDRN adds deep hydration and a plumped, dewy look. A salmon DNA booster that also carries peptides gives you both.
Can I use a peptide serum and a salmon DNA booster together?
Yes, but a multi peptide salmon DNA booster already combines them, which keeps your routine simple. Introduce one new product at a time and patch test first.
Where can I buy a salmon DNA skin booster in Australia?

The Salmon DNA Method
