Today’s recipe: A powerful and soothing 5% Niacinamide & Cucumber Facial Toner

Niacinamide, also known as Vitamin B3, is a powerful and popular ingredient in skin care that can work wonders. It’s a versatile ingredient that’s relatively easy to work with while providing unique benefits in terms of helping create a stable, healthy-looking, youthful glow.

Here are some of the main benefits:

  • Strong antioxidant
  • Contributes to a healthy overall look of the skin – great in urban or polluted environments to help skin remain happy
  • Reduces the appearance of pores
  • Increases hydration – If you have dry skin consider combining niacinamide with glycerin and carrier oils
  • Balancing and brightening – helps skin stay balanced in appearance
  • Soothing unhappy skin – suitable for oily and teenage skin

Given that niacinamide is water soluble, adding it to toners is an easy way to deliver all the benefits to skin before then applying oil-based serums or moisturizers. Here we have a quick recipe to add niacinamide to our Cucumber Facial Toner, though any of our toners would be a great fit!

Difficulty level: Beginner

Approximate yield: 1 Pound (approximately 8 x 2oz toners)

Equipment Needed

  • Heat-proof mixing bowl or beaker
  • Scale
  • Spoon, whisk, or blender
  • Hot plate
