Isntree C-Niacin Toning Ampoule(Whitening)

 A vitamin-enriched brightening ampoule that makes dark and dull complexion radiant Infused with 69% of Hippophae Rhamnoides Fruit Extract and niacinamide to brighten skin tone.

 Butylene glycol, or let’s just call it BG, is a multi-tasking colorless, syrupy liquid. It’s a great pick for creating a nice feeling product.  

BG’s main job is usually to be a solvent for the other ingredients. Other tasks include helping the product to absorb faster and deeper into the skin (penetration enhancer), making the product spread nicely over the skin (slip agent), and attracting water (humectant) into the skin.
