this item A TRUE MULTI-TASKER: One drop of Vibriance Super C Vitamin C Facial Serum nourishes your skin with a powerful combination of skin nutrients. This multi-tasking vitamin C serum combines several products into one, making you look more vibrant than ever. NOT JUST WATER: When it comes to vitamin C face serum, the ordinary face serum is watered down and ineffective. Our formula, on the other hand, is a high-quality and highly concentrated vitamin C serum. The base ingredient in Vibriance Super C Serum is made from evaporated lemons, while other brands’ base ingredient is simply tap water.
