Sia Botanics Brightening Vitamin C Face Serum 1 Ounce

In its pure form, Vitamin C (L Ascorbic Acid and Sodium Ascorbyl Phosphate) is the most effective antioxidant ever studied but when it comes into contact with oxygen it rapidly degrades. Sia Botanics has created the perfect solution for super active Vitamin C delivery. Each serum is packaged in a glass bottle with a pump to minimize air contact but the secret to keeping the vitamin C fresh and active is a technique borrowed from the wine industry. We hand top each bottle with an inert gas that does is heavier than air. This gas displaces the air, forming an invisible barrier that keeps air from coming into contact with the serum. It does not interact with the serum at all and is the same technique that organic vineyards use to preserve wine barrels.
