Vitamin C

Vitamin C, or ascorbic acid, is a potent antioxidant that's used in Korean skincare due to its wide range of skin benefits. It helps protect the skin against free radical damage, brightens the complexion, evens out skin tone, and stimulates collagen production, which aids in reducing the appearance of fine lines and wrinkles.

Vitamin C skincare products are generally suitable for all skin types. However, those with sensitive skin should start with a lower concentration and gradually build up, as Vitamin C can cause some initial skin sensitivity. As always, a patch test is recommended when introducing a new product to your routine.

Vitamin C is renowned for its ability to brighten the skin and fade hyperpigmentation and dark spots. It also aids in collagen production, which can help reduce the appearance of fine lines and wrinkles, leading to a more youthful complexion.

Vitamin C products typically come in the form of serums, which should be applied after cleansing and toning, but before moisturizing. It's also advisable to use them in your morning routine, followed by a sunscreen, as Vitamin C enhances your skin's protection against harmful UV rays.

Results from using Vitamin C skincare products can vary depending on the individual and the skin concern. Some improvements, like increased radiance and smoother skin, might be noticeable within a few weeks. However, other concerns such as hyperpigmentation and fine lines might take a few months to improve.

Choose a product with an appropriate Vitamin C concentration based on your skin type and tolerance. For beginners or those with sensitive skin, a product with a lower concentration (about 5-10%) would be a good start. Also, Vitamin C can be unstable and degrade when exposed to light and air, so opt for products in opaque, air-restrictive packaging.
