Do you know that your skincare product like Vitamin C serum can go bad?
Vitamin C serum is indeed one of the best products to use in summer as it prevents your skin from being damaged due to excessive sunlight. But the problem with your vitamin C serum is, it is extremely unstable. After it contacts air, heat, or light, it loses its potency and gets oxidized.
But is oxidized vitamin C serum still effective?
Although vitamin C is the most effective ingredient among your all skin care products, it does have its expiry dates. So, you have a few months to use the product if you have opened the package.
Yet, if you are still stuck on, ‘is oxidized vitamin c serum still effective?’ then read this article to get your answer!
IS IT STILL EFFECTIVE TO USE OXIDIZED VITAMIN C SERUM?
You definitely don’t want to use an expired product at the risk of your beauty! Do you?
Although a fresh vitamin C serum is clear, once you open the package, it may turn normal light yellow. This color means your serum has begun oxidizing yet it is effective to be used.
However, if you notice your serum turning brown or dark yellow or in certain cases, orange, then it is best if you avoid it.
If you are thinking that, can you still use yellow vitamin C serum, then the answer is yes if the color is light yellow.
The dark color indicates that the product is not only useless but has also lost 15 to 20% of its potency. It may also establish an obstruction on the skin's surface that might prevent other active components and formulations from penetrating the skin effectively.
There are numerous varieties of vitamin C available according to your skin type.
If your skin is oily, then Vitamin C forms which are water-soluble like L-ascorbic acid and sodium ascorbyl phosphate are included in serums to prevent blemishes and acne-related issues.
If your skin is dry, then vitamin C in the form of ascorbyl palmitate and tetrahexyldecyl ascorbate which are fat-soluble are used in the product to moisturize your skin well.
If you are still asking, can I use oxidized vitamin C serum, then the answer is no!
Once your vitamin C serum has undergone significant oxidation, it is advised to discontinue using them because of its diminished efficacy and potential for skin discoloration.
HOW TO PREVENT YOUR VITAMIN C SERUM FROM OXIDIZING?
You can adapt certain ways for your vitamin C serum to last longer. Here are some tips that will help you store your serum.
- Sunlight can quickly reduce your serum's efficiency and potency. So, place it in a cabinet or drawer to get the greatest effects. You should also be aware that your vitamin C serum must be packed in dark or light-blocking packaging.
- This might seem foolish to you, but oxygen must not be present in your serums. Any contact with air reduces the efficiency of vitamin C, turning it ineffective. It is quite easy to misplace a lid, therefore it is best to be careful and check before keeping your vitamin C serum.
- You may find the bathroom a perfect place to keep your serum, but it is the worst place. Your serum is sensitive to temperature therefore, frequent temperature changes and constant exposure to humidity may interfere with your serum’s effectiveness.
- If you haven’t opened your vitamin C serum, then it may last up to 3 years. Once it is opened, then the shelf life falls to 3 months. So, you have to use it within the instructed time to gain proper benefits from it.
