Vitamin C Powder
Mix a half a teaspoon of powder with a quarter cup of water to create a vitamin C toner every other day, or mix a small amount in your palm with your favourite water based facial serum, lotion, cream or moisturiser.
Expert: Soluble in water (50 mg/ml), ethanol, and ethoxydiglycol. Ascorbic acid is highly unstable in most mediums as they contain oxygen and metals. Ascorbic acid can also react with light and heat. Short-term use formulations are the most effective way around this.
Not suitable for sensitive skin.
Keep cool, dry and away from light for best results. Brown tinged powder means the ascorbic acid has reacted with moisture in the air and should be thrown out. Keep tightly closed.
Shipped in resealable paper, foiled lined bags, foil is the ultimate high barrier for oxygen, water vapour and light
