Description
What is it?
Niacinamide is a water-soluble form of Vitamin B3. Your skin doesn't make it on its own, so it has to come from what you apply or eat. It's been studied in skincare for decades, which is rare for an active this gentle — most ingredients with this much research behind them come with some irritation risk. Niacinamide doesn't.
What does it actually do?
- Helps regulate oil production, not just absorb it. According to PubMed, a clinical trial across Japanese and Caucasian populations (Draelos ZD, Matsubara A, Smiles K. "The effect of 2% niacinamide on facial sebum production." Journal of Cosmetic and Laser Therapy, 2006) found that topical 2% niacinamide significantly lowered sebum excretion rate in Japanese subjects after 2–4 weeks, and reduced casual sebum levels in Caucasian subjects after 6 weeks — working on oil at the source, unlike products that just mattify the surface.

- Strengthens the skin barrier from the inside. According to PubMed, a study on human skin cells (Tanno O, Ota Y, Kitamura N, Katsube T, Inoue S. "Nicotinamide increases biosynthesis of ceramides as well as other stratum corneum lipids to improve the epidermal permeability barrier." British Journal of Dermatology, 2000) found niacinamide increased ceramide production 4–5.5 fold in treated skin cells, and topical application reduced water loss through the skin in real-world testing. This is part of why niacinamide controls oil without leaving skin feeling stripped. DOI
- Fades dark spots and evens out tone. According to PubMed, a clinical trial in 138 subjects across two studies (Hakozaki T, Minwalla L, Zhuang J, et al. "The effect of niacinamide on reducing cutaneous pigmentation and suppression of melanosome transfer." British Journal of Dermatology, 2002) found niacinamide gave 35–68% inhibition of pigment transfer to skin cells in lab testing, and significantly reduced visible hyperpigmentation and increased skin lightness after 4 weeks of use in the clinical trial. DOI
- Calms inflammation linked to acne. According to PubMed, a double-blind trial in 76 patients (Shalita AR, Smith JG, Parish LC, Sofman MS, Chalker DK. "Topical nicotinamide compared with clindamycin gel in the treatment of inflammatory acne vulgaris." International Journal of Dermatology, 1995) found 4% topical nicotinamide gel worked as well as 1% clindamycin — a standard prescription antibiotic gel — in reducing acne lesions and severity over 8 weeks, without the resistance risk that comes with antibiotics. DOI
Who is it good for?
Genuinely most skin types. Oily, combination, acne-prone and dull or uneven-toned skin all tend to respond well. It's gentle enough for sensitive skin too, when introduced gradually. Suitable for both men and women, at almost any age.
Use with a little care if you:
- Layer it with very high-strength Vitamin C in the same routine — can cause temporary flushing in sensitive skin
- Are new to active ingredients — patch test first, as with anything new
