Your vitamin c serum has a lot of anti-aging, skin brightening, and healing properties, yet it can still be a little finicky. You have to pay extra attention to its appearance and consistency once you have opened the product.
But, how to know if vitamin C serum has oxidized or gone bad?
Vitamin C is unstable in oxygen and hence will get oxidized. So, you have to take care of it like an infant by keeping it covered properly.
Follow this article if you are worried about how to know if your vitamin C serum has oxidized.
HOW TO KNOW IF YOUR VITAMIN C SERUM IS OXIDIZED OR GONE BAD?
You may have many cosmetic or skin care products but, the shortest shelf life is vitamin c serum. As your vitamin C serum immediately reacts with oxygen, it loses most of its potency and gets expired early. It does have some signs that show it cannot be used anymore.
So, what does oxidize vitamin C serum look like?
The quickest way to find out if your vitamin C serum has oxidized is by checking out its color. A serum that contains more vitamin c has a clear appearance. But, as soon as you open the product, it will start changing its color and will become yellow or brown within 3 months.
Another way that you can predict bad vitamin c serum is how it smells. Although many products include fragrances that mask the oxidized serum smell, if you pay attention to it, you will feel a little different as compared to when your serum was fresh.
But you may be confused about what happens when vitamin C serum is oxidized.
If you cut an apple and leave it like this for a while, you will soon realize that the apple has changed its color. It's because of oxidation. Similarly, your beloved vitamin C serum which is L. Ascorbic acid faces the same scenario.
- Ascorbic acid degrades into erythrulose, which is used in self-tanning products. It causes damage to your skin and your skin will be vulnerable to more free radicals. As a result, instead of gaining benefits, you may face adverse effects of it!
USING OXIDIZED VITAMIN C SERUM:
Your oxidized vitamin C serum is technically not dangerous, it's just less potent.
So, this may have pinged your brain now, can I use oxidized vitamin C serum?
The answer is simply no!
Don’t go using your expired vitamin C serum especially if your skin is sensitive as it can cost you your beauty. The expired product can irritate your skin and can cause staining or blemishes which you don’t want to experience.
Although about 10% of vitamin C may be effective, this percentage is still not enough to treat your skin.
HOW DOES IDEAL VITAMIN C SERUM LOOK LIKE?
Your ideal vitamin c serum should come in tight packaging. A potent vitamin c serum should meet the following criteria:
- Vitamin C serum must be in the form of L- ascorbic acid.
- The PH range must be 2 to 3.5.
- Your serum should have a 20% of vitamin C concentration.
Protect your serum from heat, light as well as air. A refrigerator may be a good place for storing your serum.

Your oxidized vitamin C serum will roughly take 3 months once you have opened the product.
