NAD
Nicotinamide adenine dinucleotide is a coenzyme every cell uses to make energy. It is the ingredient the formula is built around.
What is in it
Seven ingredients, and what each one does
No proprietary blend and no long label. Seven things, and you can look every one of them up.
7ingredients
30ml per bottle
2drops per use
0added fragrance
Collagen extract
Collagen is the protein that keeps skin taut. Applied to the skin it holds water at the surface, which is where skin looks thin and drawn.
Arginine and glycerin
The hydration pair. Glycerin draws water into the skin and arginine helps hold it there through the day.
How it feels
A serum that disappears into the skin
On the skin
Two drops, nothing more
The serum is water based and thin, so the drop holds its shape for a moment before you press it in. You use less than you think.
The same skin, seconds later. Nothing left sitting on top.
Afterwards
No film, no shine
That is why the second picture looks like nothing is there. The serum does not sit on top of the skin, and it leaves neither tackiness nor a greasy shine.
It goes on before your moisturiser, because this is the thinnest layer in the routine.

What changes
The first week, and the month after
Hydration shows first. Firmness takes longer. That is why the window is sixty days and not seven.
The first week
Skin stops looking dry and drawn. Make-up sits better, and you stop looking tired on mornings you slept well.
Weeks two to four
The slower change. Skin feels smoother, and the lines make-up used to settle into are less obvious.
Day sixty
The guarantee runs out and you decide. If you see no difference, you email us and we refund you in full.
What is in every drop
Seven ingredients. Nothing else.
Most skincare routines mean a cupboard of jars and a long label nobody reads. This is one bottle and seven things.
Aqua
The base that makes this a water-light serum instead of a heavy cream. It sinks in and disappears.
Glycerin
Soft, comfortable skin all day. It pulls water into the surface and holds it there, so skin stops feeling tight by mid afternoon.
1,2-Hexanediol
Keeps the bottle as clean on day sixty as it was on day one, and no parabens.
Carbomer
Turns the water into a gel that stays where you put it. Two drops cover your whole face instead of running off your fingers.
Arginine
An amino acid your skin already makes to hold water. Topping it up is why skin still feels comfortable in the evening.
NAD
The coenzyme every cell uses to make energy. It is why this is a treatment serum and not another moisturiser.
Collagen extract
Collagen is what holds skin taut, and you make less of it every year. This puts it back at the surface, where skin looks thinnest.
No fragrance. No colour. No essential oils.
10,000+ NAD serums bought every month.

Frequently asked questions
Questions, answered properly
What is NAERVIA?
NAERVIA is a 30 ml glass dropper bottle of NAD serum. Seven ingredients, nothing else. Two drops evening and morning, and one bottle lasts about a month.
How will this help my skin?
Collagen is what makes skin look springy and bouncy. The collagen extract in NAERVIA works at the surface, holding water against the skin so it looks fuller and more youthful.
NAD is the fuel your skin cells run on. The less you have, the more tired you look.
Glycerin holds water in the skin, so it stays hydrated and soft all day.
The combination of all three will keep your skin hydrated, glowing and looking youthful.
Does it have fragrance?
No. No fragrance, no colour and no essential oils. That is where most reactions come from.
What does it feel like?
Light and slightly slippy from the glycerin, then it sinks in within a minute and leaves nothing tacky behind. It sits fine under make-up.
How do I use it?
Two drops on clean dry skin, evening and morning, before your moisturiser. Press it in with your fingertips rather than rubbing it around.
How long does a bottle last?
30 ml lasts about a month at two drops twice a day. Three bottles is about three months and five bottles about five months.
Will it suit sensitive skin?
There is no fragrance, no dye and no essential oil in it, which is what most reactions come from. It is still sensible to patch test on your inner arm for a day before you put anything new on your face.
Can I use it with retinol or vitamin C?
Yes. This is water based, so it goes on first, before anything heavier. If your skin is still getting used to retinol, alternate nights rather than layering both every evening.
How long before I see anything?
Hydration shows first, usually within the first week, and skin stops looking dry and drawn. Firmness improves slowly. Give it the full 60 days.
How long does delivery take?
Enjoy free priority tracked shipping on every order. Your order is prepared within 1 to 2 business days of being placed, and it reaches you in 12 to 25 days.
Will I be charged customs or VAT?
Orders arriving in Iceland may attract Icelandic VAT and a postal handling fee, set by the Icelandic authorities rather than by us. We declare every parcel at its real value, which is the only way that ends well for you.
