Niacinamide 20% Serum
A high-strength niacinamide serum paired with zinc, aimed at oily and blemish-prone skin that wants a more even, less shiny complexion. It is a plain, no-frills formula: alcohol-free, fragrance-free, and light enough to sit under the rest of your routine. A good fit for anyone working on dark spots, the look of pores, or midday shine.
More detail
The core actives are 20% niacinamide, which helps brighten, even out tone, support the skin barrier and keep oil in check, plus 4% zinc PCA that calms excess sebum and suits breakout-prone skin. Arbutin adds extra help fading dark spots, while glycerin, sodium hyaluronate, aloe and green tea keep things hydrated and soothed. The texture is a lightweight, quick-absorbing liquid you apply after cleansing, morning and/or night, before your moisturizer. Because 20% is a high concentration of niacinamide, introduce it slowly and patch test first, since very sensitive skin can occasionally flush or tingle. It layers cleanly under sunscreen and other products without pilling.
