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

If you are looking at investing in a Vitamin C serum, you are right to wonder about its shelf life and effectiveness, as well as the mileage you can get out of a bottle. When it comes to the popular Vitamin C + E, Ferulic acid serum, it’s pretty well known that the ascorbic acid in the skincare serum is prone to breaking down in light and heat. What you might not realize is that individual manufacturers can do a lot to help that.

Increasing the Shelf Life of Serum

Anything that can be done to decrease the ascorbic acid’s exposure to light, heat, and air will help to keep it from breaking down into its component molecules. That means it will also lengthen the life of your Vitamin C serum. Timeless serum formulas are packaged in an opaque bottle with a tight seal, and that is designed to help them stay active for longer. Storing them in a cool dry place fully sealed will help lengthen that shelf life even more.

How Long Does a Bottle Last With Continuous Use?

If you are wondering how long a bottle of serum will last, it is hard to tell from the outside. Looking at Vitamin C serum reviews will help you get a feel for the differences from brand to brand, but even those reviews usually fail to mention the ways that individual use habits can affect a serum bottle’s lifespan. Factors that can change how long your bottle lasts include:

  • Amount used in a single application
  • Size of the application area
  • Frequency of application

While there is not an exact date for when a skin care serum containing vitamin C and ferulic acid will expire, there are environmental factors — mainly light and air — that can affect the serum's shelf life and cause it to become ineffective at a quicker pace. As you wonder to yourself "how long does vitamin C serum last," consider that there is a way to extend the shelf life and get the most for your money.

Transfer It Into Smaller Bottles

Most of the time, you buy vitamin C serums that include ferulic acid in bottles meant to hold one ounce. This may not seem like much but when you consider that you only need a small amount of the serum each day, an ounce lasts a long time. Unfortunately, each time you open the bottle, the serum is exposed to light and air, which causes it to lose its effectiveness.

To make your product last longer, consider purchasing two dark-colored half-ounce bottles online and transferring your product to them. Put half into a bottle with a dropper, which you can use immediately. Put the other half into a bottle with a traditional cap and store it for later. Because half of the product will be completely in the dark until you are ready to use it, you save the product and save money in the process.

How to Tell if Your Serum Has Lost Its Effectiveness

Your vitamin C serum shelf life greatly depends on how often you use your product. The more often you use it, the lower its shelf life. This is because each time you open the bottle, air and light enter and cause oxidation to occur. Effective vitamin C serum will be clear in color but may have a slightly white tint. If you notice that your serum has turned orange or brown, it is time to purchase a new bottle.
