A firming peptide serum for lines. An NAD+ boost for tired, dull skin. Collagen hydration for that plump, rested glow. Normally that's three bottles, three steps and three bills.

We put them in one formula. It layers perfectly under moisturizer and makeup, morning and night. Apply, press in, done.

  • Visibly firms face & neck
  • Softens the look of fine lines
  • Restores a plump, rested glow
How does it work?

How does it work?

Right away: hydrolyzed collagen, hyaluronic acid and panthenol draw in moisture and plump the skin's surface. Dry lines look softer the same day, and skin gets that rested glow back.

Within weeks: NAD+ and niacinamide support your skin's overnight renewal — tone looks brighter, texture more refined, pores less obvious.

Over time: the EGF peptide (sh-Oligopeptide-1) and adenosine — the actives Korean dermatology built its reputation on — smooth the look of expression lines on the forehead, around the eyes and along the neck.

Stay consistent, morning and night. Your mirror does the rest.

Frequently asked questions

Everything you might want to know before your first bar.

How do I use it?

Morning and night, after cleansing, dispense 2–3 drops into your palm. Press gently into the face, then sweep upward along the jaw and neck. Follow with your moisturizer — and in the morning, always finish with SPF.

When will I see results?

Hydration and glow are immediate — skin looks plumper and dewier from the first uses. Brightening takes longer: expect a more even tone within 2–4 weeks. The peptides are the slow burn — the look of fine lines keeps improving over 4–8 weeks of consistent use. That's why we give you 60 days to judge it.

Can I use it with my other skincare?

Yes. It plays well with retinol, moisturizers and SPF. Apply the serum first on clean skin, let it absorb for a minute, then layer the rest of your routine on top. If you use a retinol at night, apply the serum first and the retinol after.

Is it okay for sensitive skin?

The formula is fragrance-free, non-comedogenic and contains no drying alcohol. As with any new skincare, do a small patch test on your inner arm first if your skin reacts easily.

How does the money-back guarantee work?

Use it morning and night, on your skin, in your mirror. If you're not seeing smoother, firmer-looking skin within 60 days, let us know and we'll process your full refund. No questions asked.

Where do you ship?

We ship across the United States — free on orders over $40. Most orders arrive within a few business days; you'll get a tracking link the moment yours leaves the warehouse.
