Niacinamide
A form of vitamin B3 that supports the skin's barrier function and helps with the look of oiliness and uneven tone.
Niacinamide is a water-soluble form of vitamin B3 (nicotinamide) and one of the most versatile actives you'll find in skincare. It plays a role in cellular energy production and supports the synthesis of ceramides, the lipids that help hold your skin barrier together. Because it's well-tolerated across most skin types, it's become a staple ingredient in serums, moisturisers, and even sunscreens.
In formulations, niacinamide is typically used at concentrations between 2% and 10%. At the lower end, it supports the skin's natural barrier recovery and helps the skin retain moisture by bolstering its natural lipid layer. At higher concentrations, evidence suggests it can help manage the look of excess oil and reduce the appearance of enlarged pores and uneven skin tone by influencing melanin transfer within the skin. It's water-based, so it layers easily under oils and heavier creams, and it's stable across a wide pH range, which makes it compatible with most other actives in your routine.
For shoppers, niacinamide is worth considering if you're looking for a gentle, broadly supportive ingredient. It pairs well with hyaluronic acid for hydration, and can sit alongside retinoids or vitamin C in a routine, though if you're combining multiple actives, introduce them gradually to see how your skin responds. It's a solid choice when you're starting out with actives because it rarely causes irritation.
That said, niacinamide isn't a miracle worker. It won't replace sunscreen for pigmentation concerns, and very high concentrations can occasionally cause mild flushing in sensitive skin. If you're dealing with persistent skin concerns that aren't responding to a consistent routine, it's always reasonable to speak with a dermatologist or skincare professional for personalised guidance.
