By age 28 your dermis loses collagen 1.2% faster than it rebuilds. Surface products can't reach what's already gone.

Four reasons
Why we built it this way.
REASON 01
Marine collagen, not bovine.
Smaller peptide weight (3 kDa) means it reaches the dermis instead of sitting on top.
FULL BLEED · droplet macro
REASON 02
Formulated wet.
Cold-blended and oxygen-free. No heat means no active degradation between lab and bottle.
FULL BLEED · serum being poured
REASON 03
Bakuchiol for the retinol-tired.
Plant-derived alternative with comparable wrinkle reduction at 8 weeks — and no peeling, no sun panic.
FULL BLEED · skin glow
REASON 04
One bottle = 60 nights.
Two pumps a night. Glass apothecary bottle is refillable from month four.

The science
How a 3 kDa peptide actually gets in.
Most collagen molecules are 300,000 Da — far too large to cross the stratum corneum. We enzymatically cleave our peptides to 3,000 Da, small enough to slip between corneocytes and into living tissue.

The ritual
Three steps. 30 seconds.
No 12-step routine. No layering chart. Just this.
drop
STEP 01
Cleanse, pat half-dry.
Damp skin pulls the serum in twice as fast.
pump
STEP 02
Two pumps, palms.
Warm between hands for 3 seconds. Press onto cheeks and forehead.
You don't need to. Bakuchiol gives you the retinol benefits without the irritation cycle. If you're already on retinol and like it, alternate nights.
When will I see results?
+
Glow shows up first, usually by week 2–3. Texture changes follow around week 4. Fine line reduction is measurable at week 8 in our clinical panel.
Is it safe in pregnancy?
+
Bakuchiol is generally considered safer than retinoids in pregnancy, but always confirm with your OB. We provide a full ingredient list for your records.
Vegan? Cruelty-free?
+
Cruelty-free, yes. Vegan, no — we use marine-sourced collagen. There is no plant collagen on Earth that performs at 3 kDa, and we don't pretend otherwise.
How does the refill work?
+
Your second order ships as a glass-free pouch. You decant it into the bottle you already own, saving ~40g of glass per cycle.
How does the trial work?
+
Use the full bottle for 60 nights. If it isn't working for your skin, email a single sentence and we refund — no return required.
