Salmon DNA and peptides are two of the most talked about ingredients in skincare this year. Some global formulas have started blending both into a single ampoule. We stock them as two separate, specialised boosters rather than one blended formula, which is a deliberate choice, but it leaves a genuine question. Can the two be combined in an at home routine and if so, how should that actually work alongside microneedling.
What each ingredient is actually doing
Salmon DNA, or PDRN, is a regenerative signalling ingredient. It speaks to receptors on fibroblasts in the dermis, encouraging the skin's own repair processes rather than delivering a finished result directly. We cover the full mechanism in Salmon DNA Serum: What PDRN Actually Does for Your Skin. Our Stayve Salmon DNA Gold PDRN Skin Booster holds 5,000ppm of PDRN and tends to suit skin dealing with early lines, dullness or a texture that has felt less resilient recently.
Peptides work differently. Our Stayve EGF Peptide Gold combines adenosine with a peptide complex, including copper tripeptide and hexapeptide, designed to support the skin's natural firmness processes over time. We compare it directly against a hydration focused booster in Gold Peptide or Hyaluronic Acid. Peptides tend to be reached for by anyone noticing a loss of firmness or definition along the jawline specifically, rather than dullness or general texture.
Why they are not competing for the same job
PDRN and peptides both ultimately support collagen related activity in the skin, but through different signalling pathways and with a slightly different emphasis. A 2025 review in Biomaterials Research sets out how PDRN activates adenosine A2A receptors to support fibroblast proliferation and tissue repair broadly across the skin. Peptides work more specifically on signalling pathways tied to firmness and structural support. That distinction is why the two are not really competing for the same job. It is also why some people ask about using both rather than choosing one over the other permanently.
How to actually structure a routine using both
Both boosters are formulated to be used with microneedling, applied during or straight after the pass depending on your device's needle depth. Neither product is intended to be mixed together and applied in a single pass. The straightforward, sensible way to use both is to alternate them between sessions rather than combine them in one, since standard depth microneedling sessions are already spaced four to six weeks apart to give your skin proper recovery time. Using Salmon DNA Gold in one session and Stayve EGF Peptide Gold in the next gives your skin exposure to both mechanisms across a course, without introducing two actives into the skin during the same open channel window.
If you have not built a microneedling routine yet, our guide to what to apply after microneedling covers device choice, technique and the depth dependent timing for applying either booster.
Which one to start with
If dullness, texture or a general lack of resilience is your main concern, start with Salmon DNA Gold. If a loss of firmness or definition along the jawline is what bothers you day to day, start with the peptide formula. Both build gradually over a course of sessions rather than working overnight, so choosing based on your main concern rather than which ingredient is trending is what actually determines whether you stick with it. Our Korean skin boosters beginner's guide covers the full range if you are still working out where to start.
Common questions
Can I use Salmon DNA and peptide boosters together?
Yes, but not mixed into the same microneedling pass. The sensible approach is to alternate them between sessions, using one booster in one session and the other in the next, since both are designed around the same four to six week microneedling cadence.
Should I alternate them or use both in one session?
Alternate them. Neither product is formulated to be mixed with the other and applied during the same pass. Alternating between sessions still gives your skin exposure to both mechanisms across a course without introducing two actives into the skin at once.
Which booster should I start with?
Start based on your main concern. Salmon DNA Gold suits dullness, early lines and general texture. The peptide formula suits a loss of firmness or definition along the jawline specifically.
How long before I can switch between them?
Follow your microneedling schedule rather than a separate timeline for the boosters themselves. Standard depth sessions are spaced four to six weeks apart, so switching booster at your next scheduled session is straightforward.
