The K-beauty molecule everyone's talking about
Most K-beauty is made for 20-year-olds. This is made for your age.
- Two actives, one bottle. PDRN rebuilds, Hexapeptide-8 smooths. Most serums do only one.
- 20,000 ppm PDRN, 4× the watered-down serums going viral
- "Topical Botox" peptide that softens expression lines without freezing
- Built for maturing skin, not 20-year-olds
- The molecule Korean clinics inject, now at home

Who What WearMost PDRN serums aren't built for your skin
PDRN is everywhere right now, but most of what's going viral is made for 20-year-olds and watered down to 2,000–10,000 ppm, just enough to print "PDRN" on the label.
If you're past your early 30s and seeing fine lines and lost firmness, you need the two things those serums skip: clinical concentration (Dr. Song's runs 20,000 ppm, 4× stronger) and a formula built for maturing skin. This is both.
Get the PDRN Serum →Two clinic procedures, in one bottle
Most PDRN serums are PDRN alone. Dr. Song pairs two actives: PDRN rebuilds the structure, Hexapeptide-8 smooths the lines on top. The salmon facial and the Botox peptide, in one bottle.

PDRN at 20,000 ppm
Salmon-DNA fragments, molecularly close to human DNA: a powerful growth factor. The molecule Korean clinics inject for skin repair, here made topical. Rebuilds collagen I & III at the source.
Acetyl Hexapeptide-8
The peptide chemists call "topical Botox." It relaxes the expression lines around your eyes and mouth, smoothing and softening instead of freezing.
Low-molecular-weight Hyaluronic Acid
Small enough to carry the actives deep instead of sitting on top. It's also why the serum absorbs in seconds with no sticky film.

How to use it

- Apply. A few drops, pressed into damp skin. Around the eyes, not too close.
- Lock it in. Moisturizer over the top.
- AM only: finish with SPF. UV undoes the work.
Reviews
“I started using Dr Song PDRN Serum at night and noticed my skin looked more hydrated and refreshed within the first week. It has a lightweight texture, layers well under moisturizer, and gives my skin that smooth, healthy-looking glow without feeling sticky.”
“I'm picky with serums because my skin can get dry and sensitive, but this one feels really comforting. After a few weeks, my skin looked smoother and more hydrated, and my makeup sat better throughout the day.”
“I wanted something that helped my skin look less tired, and this has been perfect. The formula absorbs quickly, doesn't pill under makeup, and leaves my complexion looking brighter and more even. I've already added it to my repeat-buy list.”

Questions, answered
Is PDRN (salmon DNA) safe?
Yes. Korean and European clinics have used PDRN for over a decade. The salmon proteins that trigger fish allergies are removed in purification, leaving the regenerative DNA fragment.
Gentle enough for sensitive skin?
Yes. Fragrance-free, alcohol-free, pH-balanced. No purge, no peeling. If retinol left your skin reactive, this is the active you can stay on.
How fast will I see results?
Hydration and glow in the first week; firmer, smoother skin by weeks 4–6. The 60-day guarantee gives you the full cycle to judge.
