HOW LONG DOES THE SKIN CARE SERUM WITH VITAMIN C AND FERULIC ACID LAST?

HOW LONG DOES THE SKIN CARE SERUM WITH VITAMIN C AND FERULIC ACID LAST?

An effective Vitamin C Serum is a great skincare product for maintaining healthy, glowing skin. Known as one of nature’s most powerful antioxidants, Vitamin C helps fight the damaging effects of the sun's rays and other environmental factors. Vitamin C is also an essential nutrient for our bodies and works to counteract aging that comes from free radical damage. The Vitamin C in the Timeless serums is derived from L-Ascorbic Acid, one of the most effective forms of this active ingredient. 

INCREASING THE SHELF LIFE OF SERUM

The shelf life of serum depends on the various ingredients in it, but all serums have an expiration date. L-Ascorbic Acid (vitamin C in its natural form) is particularly unstable and decreases in efficiency from exposure to air, light and varied temperatures. Vitamin C in a skin care serum is even more likely to oxidize due to its acidic formulation. 

HOW LONG DOES VITAMIN C SERUM LAST?

When freshly manufactured, the 20% Vitamin C + E Ferulic Acid Serum will be a watery consistency and cloudy in appearance. As the serum begins to age it will slowly appear more yellow in color due to the natural oxidation process. Once it turns orange or brown it’s no longer an effective Vitamin C serum

It’s important to differentiate between an expired product and a product that is no longer effective. Although your Vitamin C serum will lose its efficacy once oxidized, the product does not become harmful to the skin until it's expiration date, approximately one year after manufacturing. For best results, we recommend using your Vitamin C serum within 3 to 6 month of purchase, when it is fresh and most effective.

Direct heat and sunlight accelerate the degradation of the product.  

The stages of CEF Shelf Life
 
 How do I know if my CEF serum is fresh?

Anything that can be done to decrease the exposure of L-Ascorbic Acid to air, light and heat will help to maintain its potency and efficacy. You can extend the Vitamin C serum’s shelf life by storing it somewhere cool, such as the refrigerator.  

The Timeless 20% Vitamin C + E Ferulic Acid Serum is packaged in a special opaque, airless pump bottle to protect the product’s integrity. It also stops contaminants - think unclean hands or water as well as preventing light from entering and breaking down the high concentration of L-Ascorbic Acid.  

HOW TO GET THE BEST RESULTS FROM YOUR VITAMIN C + E FERULIC ACID SERUM

  1.   When you buy Vitamin C in a skincare serum, look for one that also includes Vitamin E + Ferulic Acid. All three of these actives are antioxidants that support each other, stabilizing the Vitamin C and helping to fight free radical damage as well as increase collagen production.  
  2.   The Timeless Serum is best used in the DAY unless you are sun sensitive then you should apply at night before bed.
  3.   Avoid use of a potent Vitamin C with other stimulating ingredients to minimize irritation or inflammation.
  4.   Following application of Vitamin C serum, be sure to hydrate, moisturize and protect the skin for best results.
