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.
