The reason every eye cream you've tried never worked.

Every other eye cream is built for a different problem — caffeine for puffiness, vitamin C for refreshing, retinol for fine lines. Not one is aimed at what actually causes dark circles.

The real cause is thin under-eye skin that lets the vessels beneath show through — whether yours came from genetics, aging, bad sleep or stress. Peptina is the first formula built to fix it — clinically-proven copper peptide (GHK-Cu) thickens that skin and reinforces the fragile capillary walls beneath it, so the darkness fades from below instead of being covered up.

  • 1
    The skin you're looking through is 0.5mm thinFour times thinner than the skin on the rest of your face. The vessels beneath it show through as shadow. Whatever set it off, this is what you're actually seeing.
  • 2
    GHK-Cu rebuilds what everything else ignoredCopper peptide is the only ingredient with published clinical data on reinforcing the exact structures behind the shadow: thicker skin, stronger capillary walls.
  • 3
    Cold steel works the second it touches youThe stainless-steel rollerball smooths puffiness and boosts microcirculation on contact — an instant result while the peptide does the slow, structural work.

Dark circles, actually faded.

What's inside every bottle.

Four ingredients. Each one earns its place.

GHK-Cu

Copper Tripeptide-1

The hero. It strengthens fragile capillary walls and rebuilds collagen in thin under-eye skin — the only copper peptide with published clinical data on the vascular shadow itself.

Niacinamide

Vitamin B3

Evens out tone and reinforces the skin barrier, so the under-eye area looks brighter, calmer and less translucent.

Hyaluronic Acid

Sodium Hyaluronate

Draws moisture deep into paper-thin skin and plumps the surface — so light reflects off it instead of disappearing into shadow.

Ceramide NP

Skin-identical ceramide

Rebuilds the moisture barrier of fragile eye-area skin, keeping it resilient and locking your results in.

I thought I was stuck with them.
“My dark circles are completely genetic, my dad has the exact same ones. I'd basically given up. Three months on Peptina and for the first time they're genuinely lighter, not just covered up. Still slightly in shock.”

After years of wasting money.
“Caffeine serums, vitamin C, gold eye masks, two separate miracle eye creams. I have a whole drawer of failures. Peptina is the only thing that touched the actual darkness instead of just the puffiness.”

The Science Behind Peptina
The copper peptide GHK-Cu has decades of peer-reviewed research on skin matrix repair, collagen synthesis, and tissue remodeling. Peptina's 0.5% stabilized formulation is built on that body of work.

Questions, real ones.

Will it work if my dark circles are genetic?
In most cases, yes. "Genetic" dark circles are almost always vascular — you inherited thinner skin or a more visible capillary network, not a permanent stain. Try the press test yourself — press gently on the dark area for a second; if it briefly lightens, your circles are vascular, and those capillaries can be strengthened. GHK-Cu is the ingredient with published data on exactly that. Inherited has never meant unfixable. (If your circles are structural hollowing or pure pigmentation, a topical won't fix those — see a dermatologist.)
What's different between Peptina and The Ordinary's caffeine solution?
Caffeine constricts blood vessels — it reduces puffiness, not darkness. Peptina's GHK-Cu strengthens the capillary walls showing through your skin, which is what creates the shadow. Different mechanism, different outcome. Most women we talk to have tried caffeine first. That's fine — we're what comes after.
My eye area is sensitive — is this safe?
Fragrance-free, dye-free, dermatologist-tested. No vitamin C (cancels copper), no strong acids, no retinol — just the stabilized peptide and supporting hydrators. Formulated specifically for thinner eye-area skin. Patch test if you're very reactive.
Can I use it with retinol?
Yes — different times of day, though. Retinol at night on the rest of your face, Peptina around the eye AM and PM. Copper and retinol don't deactivate each other, but eye-area skin doesn't want both at once. Keep them spatially separate.
How long until I see results?
Visible depuffing from the cold metal roller: immediate. Visible brightening and dark-circle fade: 2-4 weeks for most customers, with meaningful result by 6-8 weeks, and the full fade between weeks 8 and 12. That's why the 3-Bottle Kit is the supply most customers choose — it covers the whole transformation window.
What happens when I stop using it?
Most of the fade holds for weeks because the capillary wall is actually stronger. But continued use maintains the result — vascular circles are something you manage, not something you cure once. There's no subscription and nothing to cancel: you simply pick up another bottle if and when you want to keep it locked in.

Stop covering. Start fading.

60-day money-back guarantee. Ships in 24 hours. If the mechanism doesn't work for you, we refund you in full.
