Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is essential for human health. It is found naturally in many fruits and vegetables, such as oranges, strawberries, and bell peppers.
In skincare products, Vitamin C is used for its antioxidant properties, which help to protect the skin against damage from free radicals. It has also been shown to help brighten the skin and reduce the appearance of dark spots and hyperpigmentation caused by sun exposure and aging. Vitamin C works by inhibiting the production of melanin, which is the pigment that gives our skin its color.
Recent studies have also suggested that Vitamin C may help to boost collagen production in the skin, which can help to reduce the appearance of fine lines and wrinkles. Additionally, Vitamin C has been shown to have anti-inflammatory properties, meaning it may help to reduce redness and irritation in the skin.
Overall, Vitamin C is a safe and effective ingredient that can provide many benefits for the skin. However, it's important to use products containing Vitamin C as directed and to choose a stable form of Vitamin C to ensure maximum effectiveness. Additionally, it's important to wear sunscreen to protect the skin from further damage and to achieve the best results.
It is approved to use as food additive in EU and generally recognized as safe food substance in US.
