What role does L-Absorbic acid primarily serve in skincare?

1. Exfoliant

2. Antioxidant

3. Moisturizer

4. Skin brightening agent

The correct answer is: Antioxidant

L-Ascorbic acid, commonly known as Vitamin C, primarily functions as an antioxidant in skincare formulations. Its primary role is to protect the skin from oxidative stress caused by free radicals, which are unstable molecules that can damage cells and lead to signs of aging, such as wrinkles and fine lines. By neutralizing these free radicals, L-ascorbic acid helps to prevent premature aging and promotes overall skin health. Additionally, L-ascorbic acid can also contribute to skin brightening by aiding in the inhibition of melanin production; hence, it is often associated with skin brightening benefits. However, its foremost and recognized role in skincare is as an antioxidant, which is crucial for maintaining the skin’s integrity against environmental aggressors like UV rays and pollution. This protective action makes it a key ingredient in many skincare products aimed at providing anti-aging benefits and enhancing skin radiance.
