For a long time, researchers have been trying to find a way for Vitamin C to penetrate the skin. However, now, concentrated Vitamin C creams applied topically have been shown to penetrate the skin eight-fold and reach the dermal mantle, where collagen is produced. Vitamin C works at the cellular level and helps to rebuild the skin fibers, restoring weakened collagen. As a potent antioxidant, it also seems to prevent sun damage even after sun exposure, although it is not an SPF itself but can act as a weak SPF helper. Vitamin C helps to break the chain of damage caused by free radicals, halting or slowing skin damage. Because it is absorbed into the skin, it cannot be washed off by water or perspiration. Scientific studies have found that Vitamin C also chemically reacts to ultraviolet light, creating an anti-inflammatory interaction that helps reduce sunburn. With the thinning of the earth’s protective ozone layer and increased environmental pollution, our skin’s ability to protect itself has decreased, making it essential to provide it with the right vitamins and nutrients, including Vitamin C, through dietary and topical means. Vitamin C is one of the best anti-aging ingredients available, and maintaining its optimum level in the skin through dietary and topical means is crucial for good skin health. Vitamin C in the form of a serum is an excellent way to nourish the skin with the essential nutrients it needs. Serums are considered the best delivery system for the skin, also known as “skin food,” because of their light structure and easy absorption by the skin.
