Vitamin C is known for its ability to neutralize free radicals, which can help protect the skin from oxidative stress and damage caused by environmental factors like UV rays and pollution. Vitamin C plays a role in collagen synthesis, promoting skin elasticity and reducing the appearance of fine lines and wrinkles. Vit C serum can contribute to a more even skin tone by reducing hyperpigmentation and dark spots. While not a substitute for sunscreen, Vitamin C may provide some additional protection against sun damage.
