Vitamin C is a potent antioxidant that can help protect the skin from damaging free radicals caused by environmental factors such as UV radiation and pollution. It can also help to stimulate collagen production, which can improve the appearance of fine lines and wrinkles and give the skin a firmer, more youthful appearance.
Using a vitamin C serum can also help to even out the skin tone and reduce the appearance of hyperpigmentation. It can also improve the texture of the skin, making it feel smoother and look more radiant.
Vitamin C serums are typically applied after cleansing and toning and before moisturizing. They can be used in the morning and at night, although some people may prefer to use them only in the morning due to the potential for photosensitivity. It's important to follow the instructions on the product packaging and to use a sunscreen during the day to protect the skin from UV damage.
Overall, using a vitamin C serum can help to protect and improve the appearance of the skin, making it an excellent addition to any skincare routine.
