Why It Works — 6 Ingredients, One Cascade
PDRN — Salmon DNA
Wakes up the skin cells that build collagen. The same ingredient used in Rejuran injections — now in a daily dropper.
6-Types Peptide Complex
Six peptide classes working at once: relax lines, rebuild the matrix, plump the dermis. No other PDRN serum uses six.
Niacinamide
Fades dark spots in 4 weeks. Strengthens the skin barrier. Makes everything else absorb better.
Aloe Vera
Calms reactive skin instantly. Also acts as a carrier — pushing PDRN and peptides deeper into the dermis.
Glutathione
Missing from virtually every PDRN serum. Stops new dark spots from forming. Fights the dullness that makes skin look tired and aged.
Sodium Hyaluronate
Low-molecular-weight HA that goes inside the dermis — not just the surface. Holds 1,000× its weight in water. Visible plumping within the first week.

Look Instantly Like Your Younger Self Again

Most serums and supplements treat the symptom. ETERNA® treats the cause. Salmon DNA signals your skin to produce its own collagen and elastin again, firming and lifting the way it did 10 years ago.

The ETERNA® Transformation

Results That Compound Every Week

Each week builds on the last — as PDRN and peptides rebuild collagen from within, revealing skin that's visibly firmer, smoother and more lifted.

Week 1

Face and neck look instantly firmer.

Within the first few days, something shifts. The skin on your face and neck feels fuller, softer. That flat, tired look you've gotten used to? It starts to fade. You wake up looking more rested.

Week 2

Fine lines soften visibly

The 6 peptide complex starts relaxing expression lines on the face and neck. Crepey areas look smoother. Skin feels more elastic and bounces back the way it used to.

Week 3

Firmer, Tighter Look

The face and neck look visibly lifted and renewed. You might catch yourself looking twice in the mirror.

Week 4

The full result that people notice

Wrinkles are barely visible anymore. Crepey texture is dramatically reduced and sagging skin is visibly firmer. Friends start asking what you’re using — results speak for themselves.

One Formula. Eternally Young Skin.

Six clinically selected actives — each targeting a specific cause of aging, sagging and loss of firmness.

Frequently Asked Questions

Because most serums sit on the surface. ETERNA® uses Salmon DNA to signal your skin cells to rebuild collagen from within — the same mechanism as Rejuran injections. It doesn't moisturize over your wrinkles. It fixes what caused them.
Yes — and it was made for it. Apply 3–5 drops every morning and press upward from neck to chin. Most women notice a visible difference in firmness within 2 weeks. Face, neck, chin — one dropper does all three.
Week 1–2: skin feels plumper, more hydrated, the dull look starts to lift. Week 2–3: fine lines soften, neck feels tighter, tone starts evening out. Week 4: visible firmness, lifted appearance, spots visibly fading. That's why we give you a full 90-day supply — results keep compounding after week 4.
Yes. ETERNA® is fragrance-free, alcohol-free and non-comedogenic. PDRN's strongest clinical evidence is in barrier repair — it calms inflammation rather than triggering it. Safe for rosacea-prone and sensitive skin.
Absolutely. Use ETERNA® in the morning, tretinoin or retinol at night. Because PDRN supports barrier repair, many women find it actually reduces the irritation retinoids cause.
PDRN is extracted from salmon DNA and has been used in clinical medicine for over a decade — mostly in Rejuran injections in South Korea. It activates the cells responsible for producing collagen and elastin. There is no detectable salmon odor in the finished formula.
Supplements add collagen from the outside — most is broken down before it reaches your skin. PDRN tells your skin to produce its own collagen, at the dermal level where it's actually used. Supplements give your skin collagen. PDRN makes your skin a collagen factory again.
Not a replacement — but it's what makes procedures less necessary. PDRN rebuilds skin structure underneath, improving actual firmness and texture over time. Many women go from quarterly Botox to not feeling the need for months.
Yes. Niacinamide fades existing spots in 3–4 weeks. Glutathione stops new ones from forming. Both actives work together — treating the spots you have and preventing the next round.
3–5 drops every morning on clean skin. Press into face, neck and jawline before moisturizer and SPF. Absorbs in under 60 seconds — no grease, no residue, no pilling under makeup.
Yes — this is one of PDRN's strongest use cases. Weight loss depletes the dermis faster than skin can adapt, leaving crepey texture on the face, neck and chin. PDRN signals the skin to rebuild structural collagen exactly where it's been lost. Most women see visible improvement within 3–4 weeks.
Not at all. Zero detectable salmon odor. ETERNA® is completely fragrance-free — no added scent, no masking fragrance. Clean, neutral finish.
90-day money-back guarantee. Try it for 90 full days. If your skin doesn't look visibly better, we refund you in full — no forms, no questions, no auto-ship traps. You keep the bottle.
The neck has fewer oil glands, thinner skin and gets more UV exposure — yet almost no one treats it. Your face gets 10 years of skincare. Your neck gets nothing. That's the disconnect. ETERNA® closes it.
Same ingredient. Rejuran delivers PDRN by needle at $800–$1,200 per session. ETERNA® delivers it topically, daily — activating the same collagen-building pathway. Results compound every day instead of fading between appointments.
