Niacin is the key ingredient in this toner. Niacinamide/Vit B3 is one of the most effective natural treatments for tissue refinement where it enhances the skins ability to de-congest and clear acne while also evening out skin tone, for a smooth complexion. In addition, I infused this toner with herbal extracts which are known to help with acne prone skin. In addition, I added aloe vera juice to promote healing of irritated skin. I recommend that you use this toner after face washing for an extra cleansing effect and to close the pores to prevent dirt and oil from clogging the pores.
