Why Vitamin C in the form of L-ascorbic acid?
L-ascorbic acid is the purest and most potent form of vitamin C and typically shows visible results faster than other derivatives. It works as a powerful antioxidant, neutralizing free radicals caused by UV exposure, pollution, and other environmental factors that can damage skin cells. L-ascorbic acid plays a critical role in collagen production, which is essential for maintaining firm, youthful skin. It supports the skin’s structure, promoting elasticity and reducing the appearance of fine lines and wrinkles. One of the most well-known benefits of L-ascorbic acid is its ability to brighten the skin by inhibiting melanin production. This helps reduce hyperpigmentation, dark spots, and uneven skin tone.
Understanding Vitamin C (Ascorbic acid) Oxidation: What It Is and How to Prevent It?
L-ascorbic acid is a skincare essential, known for its numerous benefits. However, one of the common issues with vitamin C, especially in the form of L-ascorbic acid, is oxidation. In this article, we’ll explore what causes vitamin C serums to oxidize, why it's a problem, and useful tips on how to prevent it.
What is Oxidation?
Oxidation occurs when vitamin C (L-ascorbic acid) comes into contact with air, light, or heat, causing the product to degrade over time. This process changes the serum’s color from a clear or light yellow to a dark orange or brown. Once oxidized, vitamin C reduces its potency, meaning it will no longer offer the same skincare benefits.
Tips to Prevent Vitamin C Serum Oxidation
While oxidation is inevitable over time, there are several ways to slow the process and maintain the efficacy of your vitamin C serum.
1. Store in a Cool, Dark Place
While oxidation is inevitable over time, there are several ways to slow the process and maintain the efficacy of your vitamin C serum.
2. Do not change the packaging
JUST Vitamin C 20% serum comes in dark bottle to protect the product from light exposure. Do not transfer the product into different container, otherwise you will be compromising its efficacy and stability.
3. Avoid High Temperatures
Avoid storing your JUST Vitamin C 20 % serum in hot areas, such as near a window or in a bathroom with fluctuating temperatures. Excessive heat can cause the product to degrade quickly.
4. Minimize Air Exposure
Air exposure is another key factor in oxidation. Ensure that the bottle is tightly closed after every use, and try to avoid frequent opening of the bottle.
5. Use Quickly After Opening
Although your serum may have a shelf life of 36 month, once opened, it’s best to use it within 2 months to ensure optimal potency. The fresher the serum, the more effective it will be.
Summary
Oxidation is a natural process for JUST Vitamin C 20% serum, but with proper storage and care, you can slow it down and get the most out of your skincare investment. Keep your JUST Vitamin C 20% serum in a cool, dark place, avoid heat and air exposure and make sure to use it within 2 months after opening.
