Vitamin B3
A water-soluble form of vitamin B3 that works well across most skin types and pairs with many actives.
Supports a healthy-looking barrier, helps reduce the appearance of excess oil and enlarged pores, and can improve the look of uneven tone and post-blemish marks over time.
Serums, moisturizers, toners — stable in water-based formulas; usually 2–10%.
Oily, combination, breakout-prone, and sensitive clients; those concerned with tone or pore appearance.
Generally well tolerated. Some report flushing when layered with acidic (low-pH) products — separate if irritation appears.
It does not 'thin' the skin and does not require a waiting period before other products.
Can be used alongside retinoids, hyaluronic acid, and ceramides. If irritation occurs, avoid layering directly with strong acids in the same step.
Explain it as a calm multitasker — supports the barrier and evens tone without the intensity of acids or retinoids.
