Vitamin C face capsules are a skin care product designed to provide antioxidant benefits and improve skin luminosity. Vitamin C, also known as ascorbic acid, is known for its antioxidant properties, which help fight free radicals and prevent premature skin aging. In addition, vitamin C is essential for collagen synthesis, helping to maintain skin elasticity and firmness. How to use: Capsule opening: Each capsule usually contains a precise dose of vitamin C. Carefully rotate or cut the capsule to open and release the contents. Serum application: Apply the vitamin C serum directly to the skin. You can distribute it evenly over the face and neck. Avoid the eye area if the product is not formulated for use in that area. Massage and absorption: Perform a gentle facial massage to help the serum be fully absorbed.
