The Niacinamide 15 Serum

A no-filler, 15-ingredient serum with niacinamide at its clinical maximum of 15% paired with acetyl glucosamine, zinc PCA, and allantoin in a water-thin texture that covers oil control, pore refinement, dark spots, and barrier repair in a single daily step.

Featuring 15 ingredients, every single one with a defined function, built around the highest concentration of niacinamide that's broadly considered effective and well-tolerated by most skin types. There are no fillers, no fragrance, no botanical padding. The texture absorbs almost instantly with zero stickiness or residue, which makes it one of the easiest serums to layer in a routine.

At 15%, the niacinamide is doing substantial work across multiple skin concerns simultaneously: regulating sebum production (meaningfully reducing oiliness and shine within weeks), blocking melanin transfer to fade dark spots and post-breakout marks, boosting ceramide synthesis to strengthen the barrier, and reducing the visible size of enlarged pores. Acetyl glucosamine (NAG) is the ingredient that elevates this beyond a standard niacinamide serum — research shows the niacinamide and NAG combination is synergistically more effective at fading hyperpigmentation than either ingredient alone. Zinc PCA adds antibacterial and sebum-regulating support specifically targeted at acne and congestion. The formula is fragrance-free, oil-free, fungal-acne safe, and cruelty-free.

What it is / who it's for: A maximum-strength niacinamide serum for anyone dealing with oiliness, enlarged pores, dark spots, or post-acne marks. Fragrance-free, and effective enough to be the only active serum an oily or acne-prone skin type actually needs.
