There is one ingredient I recommend to almost every client I see —
regardless of age, skin type, or concern.

It is not a peptide.
It is not retinol.
It is not vitamin C.

It is niacinamide. And most people have no idea what it is
actually doing inside their skin. 🔬

Niacinamide at 5% does four separate things at the molecular
level — each of them clinically meaningful, each of them
supported by decades of evidence. Most ingredients do one thing.
This one does four. Here is what they are.

— — —

ONE. It tells your skin to make its own ceramides.

Inside your skin cells there are enzymes called ceramide
synthases — specifically CERS2, CERS4, and CERS5. Their job is
to produce ceramides, the lipids that form the waterproofing
bilayer of your stratum corneum. In mature skin these enzymes
slow down. The bilayer becomes lipid-deficient. Water escapes.
Skin becomes chronically dry, tight, and rough — not because
you are not moisturizing enough but because your barrier is no
longer holding water the way it was designed to.

Niacinamide directly upregulates the genes that encode those
enzymes. It does not add ceramides from outside. It tells your
skin to make more of its own.

— — —

TWO. It blocks the transfer of pigment to your skin cells.

Melanin is produced by melanocytes deep in your epidermis and
then transferred to keratinocytes — the cells you can actually
see — where it shows up as the uneven tone and sun spots that
accumulate across decades. Niacinamide blocks that transfer.
The melanocytes keep making pigment. Less of it reaches the
surface. Your tone evens out quietly while you are busy doing
other things.

— — —

THREE. It is a precursor to NAD+ — the coenzyme your skin cells
use for energy and DNA repair.

Every cell in your skin runs on NAD+. Every time a UV photon
damages your DNA, NAD+ is what fuels the enzymes that repair it.
NAD+ levels decline with age. Niacinamide is one of the precursor
molecules your cells use to maintain NAD+ supply. More precursor,
more NAD+, more capacity for the daily repair work your skin is
constantly doing whether you notice it or not.

— — —

FOUR. And this is the one almost no one talks about.

Niacinamide quiets the inflammatory cytokine signaling that
drives your nervous system to keep your skin in a low-grade
sympathetic activation state. The same signaling that produces
the redness, the reactivity, the sense that your face responds
to things it did not used to respond to.

Your face is wired to your nervous system. When the cytokine
signaling is loud, your sympathetic fibers fire more, your
capillaries dilate more, your skin reacts more. Niacinamide
turns the volume down on that signal. Your face is calmer not
because the niacinamide is sedating you but because the
biological alarm bell is no longer ringing as loudly.

This is why niacinamide pairs so well with retinol, with acids,
with anything that asks something of your skin. It supports the
nervous system component of your skin’s reactivity at the same
time it is doing the other three things.

— — —

One molecule. Four independent mechanisms. Evidence base going
back decades.

If your cleanser is pH-correct, your barrier is intact, and your
niacinamide is at 5% — your skin has everything it needs to
start repairing itself.

That is not skincare. That is biochemistry. 🔬
