Niacinamide, also known as Vitamin B3, is a versatile skincare ingredient that brightens skin, reduces inflammation, and controls oil production.

Niacinamide works by strengthening the skin barrier, reducing inflammation, and regulating oil production, making it effective for a variety of skin concerns.

  • Brightens Dark Spots: Reduces the appearance of hyperpigmentation.
  • Reduces Redness: Calms and soothes irritated skin.
  • Controls Sebum Production: Helps to manage oily skin and reduce the likelihood of breakouts.

Improvements can be seen within 2-4 weeks, with significant results typically appearing within 8-12 weeks.

Niacinamide is generally well-tolerated, but some users may experience mild irritation. This is not a complete list of side effects and others may occur. Always read your Uncouth patient information leaflet prior to using your treatment.
