Key actives
Sh-Oligopeptide-1
sh-Oligopeptide-1 is a peptide made by yeast fermentation rather than synthesis, which is what the sh prefix records. It is used for the look of firmness and skin recovery after irritation.
Acetyl Dipeptide-1 Cetyl Ester
Acetyl Dipeptide-1 Cetyl Ester is a two-amino-acid peptide with a fatty cetyl tail attached, which lets it sit in the oil phase of a formula rather than only the water phase.
Palmitoyl Tripeptide-5
Palmitoyl Tripeptide-5 is a fatted three-amino-acid peptide used for the look of firmness and fine lines. The palmitoyl tail is what lets it cross an oily surface.
Acetyl Hexapeptide-1
Acetyl Hexapeptide-1 is a six-amino-acid peptide used for the look of even tone. It is one of the few peptides aimed at pigment rather than at lines.
Niacinamide
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
Theobroma Cacao (Cocoa) Seed Extract
Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.
Adenosine
Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.
How to use
- Use it in the serum slot, after toner and before your moisturizer, morning or night.
- Three or four drops for the face and neck, pressed in with the palms rather than rubbed in.
- Follow with a moisturizer to hold it in, and sunscreen last if you are using it in the morning.
- Once or twice a day. Do not pair it with a retinoid in the same routine if your skin is new to either.
Medicube NAD+ EGF Firming Serum
What does the NAD+ EGF Firming Serum actually contain?
Its ingredient list is led by Niacinamide, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.
How do I use the NAD+ EGF Firming Serum?
Use this serum as the treatment step right after toner. To apply, smooth or press onto cleansed, toned skin and follow with moisturizer. Keep it to AM/PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.
Is the NAD+ EGF Firming Serum the same formula sold in Korea, or a US version?
This NAD+ EGF Firming Serum is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.
Can I use the NAD+ EGF Firming Serum with other actives in my routine?
Yes, as long as it is used in its own step, the treatment step right after toner, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.
Who is the NAD+ EGF Firming Serum suited for?
It suits most skin types looking for treatment step right after toner rather than a single acute problem. It comes in a 30ml format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

How it works
The panel on this serum names ten forms of peptide rather than one: Sh-Oligopeptide-1, Acetyl Dipeptide-1 Cetyl Ester, Palmitoyl Tripeptide-5, Acetyl Hexapeptide-1, Acetyl Octapeptide-3, Copper Tripeptide-1, Oligopeptide-3, Oligopeptide-2, Oligopeptide-1, Hexapeptide-11. sh-Oligopeptide-1 is a peptide made by yeast fermentation rather than synthesis, which is what the sh prefix records. It is used for the look of firmness and skin recovery after irritation. On this panel it sits alongside Niacinamide, Theobroma Cacao (Cocoa) Seed Extract and Adenosine. Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
Worth knowing
- Patch test on the inner arm before the first full-face application, especially on skin that reacts easily to new products.
- Stop use and rinse off if stinging, burning, or new redness shows up rather than pushing through discomfort.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
