What people say about Niacinamide and skin & hair
“In my experience, niacinamide (not niacin) 1000-1500mg a day worked wonders in about 5-7 days.”
“Niacinamide is a great anti acne supplement. I take it orally, 1500 mg a day in one slow release tablet. It's completely changed my life! I'm so much less oily now”
“Niacinamide (500mg/day) had an incredible effect for me. I had frequent small pimples and an uneven skin tone... It was an ongoing issue for a long time and I tried a lot of things, until I found this.”

Topical treatment for postinflammatory hyperpigmentation: a systematic reviewConclusion: Retinoids, hydroxy acids and broad-spectrum sunscreen were supported by the greatest number of high-quality studies. Ongoing inflammation may be subtle, especially in darker skin phenotypes. Herein, we proposed an evidence-based algorithm for PIH based on the high-quality studies. There is a need to adopt a validated outcome measure for PIH to better compare efficacy between various treatments in future studies.
