OUR INGREDIENTS

Niacinamide

Brightens, calms, and strengthens the barrier

Evens

Reduces the appearance of hyperpigmentation and uneven skin tone.

Balances

Regulates sebum production without over-drying the skin.

Calms

Lowers inflammation associated with redness and irritation.

What it is

Vitamin B3 — one of the most versatile and well-tolerated active ingredients in modern skincare, suitable for nearly every skin type.

How it works

Niacinamide inhibits the transfer of melanin to skin cells (reducing dark spots), strengthens the skin barrier by boosting ceramide synthesis, regulates sebum production in oily areas, and calms inflammatory pathways — all simultaneously.

Niacinamide brightens, balances oil, calms inflammation, and strengthens the barrier — all in one active.

Why we chose it

Its barrier-strengthening property made it a natural partner for our Ceramide 3 foundation — niacinamide doesn’t just tolerate the ceramide-forward approach, it actively reinforces it.
