A 30 ml glass dropper bottle of NAERVIA NAD firming serum. Seven ingredients, nothing else. Two drops morning and night makes one bottle last about a month.

Water, glycerin, 1,2-hexanediol, carbomer, arginine, nicotinamide adenine dinucleotide and collagen extract. That is the full list. No added fragrance, no colour, no essential oils.

They work in different places. NAD is a coenzyme your cells use to make energy, so it belongs to the deeper business of how skin repairs itself. Collagen extract works at the surface, holding water where the skin looks thin and drawn. One underneath, one on top.

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.

Two drops on clean dry skin, morning and night, before your moisturiser. Press it in with your fingertips rather than rubbing it around. That is the whole routine.

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.

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.

Hydration shows first, usually within the first week, and skin stops looking dry and drawn. Firmness is the slower change. Give it the full thirty days before you decide.

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.

Credit and debit cards, plus Apple Pay and Google Pay. Apple Pay only appears in Safari and on iPhone, so if you cannot see it, that is why.

No. You pay once, for the packs you choose, and nothing else is ever charged to your card. There is no plan to cancel and no repeat order to forget about.
