Niacinamide for acne what the science shows

Added: 2026-05-20

[00:00:00]Most people still get prescribed antibiotic gels for acne, but one ingredient did just as well in trials without creating any antibiotic resistance at all. In a head-to-head trial, a 4% niacinamide gel cleared inflammatory acne as well as a standard antibiotic gel. The difference is niacinamide isn't an antibiotic. It calms down inflammation, helps your skin's own defense system, it reduces oil, so there's no risk of breeding resistant bacteria. It's available over the counter as well. If you've got red inflamed spots, a 4% niacinamide product morning and night is a legitimate treatment and it plays nicely with other acne ingredients like benzoyl peroxide or prescription retinoids. So, before you start another antibiotic gel, look at what you're already using. Could you swap or add in 4% niacinamide instead?
