When I go out in the sun I always make sure I use our Crystal C Serum or Lactic C Firming in the morning under my sunscreen. The main goal of incorporating topical vitamin C is to reduce oxidative stress and reduce hyperpigmentation. In a recent cosmeceutical report, studies show that “oxidative stress stimulates the production of free radicals that may denature proteins, alter cell cycles and influence the release of pro-inflammatory mediators that may trigger the induction of some inflammatory skin diseases”. 
Many people get confused about the forms of vitamin C because L-ascorbic acid is the same as sodium ascorbyl phosphate and the names are often used interchangeably. Magnesium ascorbyl phosphate, L-ascorbic acid, sodium ascorbyl phosphate and ascorbyl glucosamine are all various forms of Vitamin C considered to be effective and stable antioxidants for the skin. The percentage of actives may vary and that is why using a professional brand will typically provide more noticeable results. Years ago, when topical vitamin C products were first brought to market, the stability was an issue. Today, with new cosmetic chemistry advances, the pH levels of these “bio-available” forms of vitamin C make it much more compatible for even the most sensitive skin types.
It is important to remember that vitamin C can block tyrosinase. Tyrosinase is an enzyme important in the production of melanin (which gives our skin it’s pigment). By using the Crystal C Serum or Lactic C Firming Cream once or twice daily, on clean dry skin you help reduce oxidative stress and may potentially destroy free radical activity produced by the sun’s UV rays.
Sometimes it is hard to know what to use on your face with all the choices we have. Regardless of all the choices, if you are at a plateau, outdoors during the day, noticing some new pigmentation, or just need a change, consider incorporating vitamin c topicals into your daily routine whether in a serum or moisturizer prior to applying your sunscreen as a preventative measure that you can notice now, but enjoy for a lifetime.
