What it does
A multi-tasking vitamin B3 derivative that reduces pore appearance, calms redness, brightens uneven tone, and strengthens the skin barrier.
Best for
All skin types. Especially useful for oily, acne-prone, or sensitive skin. Typical effective range is 2-5% (10% can irritate).
The full picture
Niacinamide is one of the most versatile actives in modern skincare and the closest thing to a universal recommendation in the lifting cream category. It strengthens the skin barrier by boosting ceramide production, reduces inflammation, evens tone by interrupting melanosome transfer, and supports the conversion of NADH-NADPH for cellular energy. Unlike retinol, vitamin C, and AHAs, niacinamide is pH-flexible and stacks well with almost everything (the long-discredited 'niacinamide + vitamin C cancellation' myth has been debunked). Look for it in concentrations between 2% and 5% in lifting creams; higher concentrations can occasionally cause flushing.
Evidence
Topical niacinamide reduces transepidermal water loss, hyperpigmentation, and visible signs of photoaging in controlled studies.
