How to Properly Store your Vitamin C Serum

The regular and consistent use of a Vitamin C serum in your skin care will increase collagen production, brighten skin and boost your sun protection. However, these benefits will only come by when you store the Vitamin C product well.

Vitamin C serums are usually clear. Vitamin C is notoriously unstable, quickly degrading when exposed to air and light. This process when the serum changes color turning yellow and eventually brown is called oxidization. When Vitamin C oxidizes it changes to dehydroascorbic acid (DHAA), which then changes the color of your serum from that clear tone down to a deep brown/red based on the level of oxidation. If your serum has changed to a dark color I would suggest not using it. There is a high probability of skin irritation.

It is clear that L-Ascorbic Acid is the most effective form of Vitamin C. If your skin can tolerate it,  there are a number of highly concentrated stabilized vitamin C products on the market. These products aren’t immune to oxidization and still require proper storage.

How to Store and Use your Vitamin C Serum For Longer

  1. Purchase formulas that are clear. Some companies dye their serums, darkening the color. Steer clear of such formulas as this could hide oxidation.
  2. Purchase well-formulated products. Since Ascorbic Acid can begin to oxide/degrade as soon as it’s dissolved in water, look for products where water is NOT one of the first ingredients. It’s likely that such a product will really work. That means look for serums instead of cream based products. If water is present, look for products that use stabilizing ingredients.
  3. Proper packaging. Purchase formulas that come in dark colored bottles with air restrictors or pump packaging. Store them in a cool dark place, like the refrigerator.
  4. Reseal tightly after use/application.
