Niacinamide
Niacinamide · vitamin B3
Niacinamide is vitamin B3 — a small, stable, water-soluble vitamin, and one of the most universally tolerated actives in cosmetic science. SKEYNDOR uses it as the quiet supporting act across many ranges rather than the hero of one: wherever a formula needs barrier support, oil balance, or a second angle on uneven tone, niacinamide is usually in the room.
The work it performs
What it does
Slows the hand-over of pigment from cell to cell, so uneven tone reaches the surface less readily.
Moisturises and supports the skin's barrier — the reason it appears in post-peel formulas, where skin needs rebuilding.
Refines the appearance of pores and helps balance visible oil in blemish-prone skin.
Evens out post-blemish redness and marks, supporting the look of resilient, settled skin.
Gentle enough that professionals use it even around the eye area — a rare quality among actives this capable.

Forms & strengths
In the cabin
Niacinamide is never the headline of a cabin protocol — it is the recovery inside them. In the ProBiome Peel it goes on at the exact moment absorption peaks, holding moisture, steadying tone and rebuilding the barrier the acids have just worked.
The ProBiome Peel treatmentHandle with care
The gentlest kind of active — the professional curriculum records no cautions, no adjustment period and no contraindications for niacinamide itself. It layers happily under or over nearly everything, which is exactly why the laboratory places it in formulas for skin that is already stressed. Any care instructions on a product containing it come from its other actives, not this one.
Pairs well with
- The post-peel vitamin stackVitamins A, C, E, pro-B5 and B6 — taught as one recovery unit, with niacinamide holding moisture and tone steady.
- BakuchiolIn blemish-prone routines, bakuchiol brings retinoid-style renewal while niacinamide holds the barrier and evens post-blemish tone.
- Salicylic AcidSalicylic clears congestion inside the pore; niacinamide settles the aftermath — the Clear Balance double act.
