Is It OK To Use Expired Sunscreen?
Before you uncap the bottle, here's what you need to know about using expired sunscreen.
Let's Talk Vitamin C's
VITAMIN C IS A POWERFUL ANTIOXIDANT THAT STIMULATES COLLAGEN PRODUCTION AND HELPS TO REDUCE SIGNS OF AGING BY REPAIRING THE DAMAGE DONE BY FREE RADICALS AND THE SUN.
Vivierskin Vitamin C Serums
What makes Vivier's Vitamin C different than other Vitamin C's on the market?
Vivier's Vitamin C's are formulated with PHARMACEUTICAL grade Vitamin C, this oil-free sērum helps reduce signs of environmental damage such as fine lines, wrinkles, uneven skin texture and tone. Ideal for all skin types especially oily skin. There are 3 key factors that determine the results of a Vitamin C based product. Vivier has met all factors to ensure efficacy of product.
1) Chemical Form – The only form of Vitamin C that can be used in the body is L-Ascorbic Acid. Other forms of Vitamin C, such as Magnesium Ascorbyl Phosphate, are not recognized by the body and must be converted to L-Ascorbic Acid by the body in order to be beneficial. VivierSkin® patented Vitamin C serums contain only L-Ascorbic Acid USP. VivierSkin® Vitamin C serums are formulated using the highest grade of Vitamin C available called “USP”. “USP” stands for United States Pharmacopeia. It is the highest pharmaceutical standard recognized for quality, purity, strength and consistency.
2) Stability – When exposed to air, Vitamin C undergoes oxidation (the process which causes a sliced apple to turn brown). When oxidized, a Vitamin C formulation becomes an oxidant instead of an antioxidant, which is harmful to the skin. The formulation and grade of the Vitamin C in its raw form determine the rate at which the formulation will oxidize. The color of your Vitamin C serum will indicate its stability. Vivier's Vitamin C serums are clear to light yellow, which means they are stable. NOTE: L-Ascorbic Acid USP will tend to oxidize and change to a light yellow color with time. This change in color is natural and will not significantly alter the product's effectiveness. So check your Vitamin C's; orange to brown serums have oxidized and should not be used!
3) Absorption – Vitamin C products in the market differ on how much Vitamin C is actually absorbed and remains within the skin. The absorption of the Vitamin C is impacted by the pH as well as the absorption technology of the formulation. To be absorbed by the skin, the pH of topical Vitamin C must be between 2.3 and 3.8. Vivier Vitamin C serums have an optimal pH between 2.4 and 3.2.
- So before you decide to settle for that $20 dollar bottle of Vitamin C on the shelf of the makeup or department store, make sure that it meets the criteria of what a Vitamin C needs to make it BENEFICIAL to your skin. -
