Cons: L-ascorbic acid is not very stable and this form of vitamin C is not further stabilized by ferulic acid or the addition of vitamin E
Cellex-C International Inc. was founded in 1991, with Cellex-C being the first topical ascorbic acid formulation to be successfully commercialized. This groundbreaking product pioneered the present worldwide interest in the use of vitamin C for topical skin care products. The synergy of the original patented vitamin C complex combined with proprietary technology invented by experts at Cellex-C International Inc. sets this line of skin care products apart from all other vitamin C products with benefits that no other product can duplicate.
Skin care products with L-ascorbic acid are not as effective as once believed because this type of vitamin C is water-soluble and easily dissolves in water. L-ascorbic acid is also very unstable and oxidizes upon exposure to the air, water, and sun, making it necessary to package this ingredient in dark, air-tight containers. These features are not always feasible for skin care products, meaning products with ascorbic acid may not be very effective, especially if this ingredient is not combined with vitamin E and ferulic acid [1, 2]. This particular serum is packaged in an amber container that is meant to provide some sun/air protection for L-ascorbic acid, but as this main ingredient is not stabilized by the addition of vitamin E or ferulic acid, it may not be very effective.
More stable forms of vitamin C (THD ascorbate), in combination with vitamin E, and ferulic acid (stabilizing agent) helps boost the body's natural skin cell rejuvenation processes [1, 2].
Zinc has anti-inflammatory properties that help target skin problems such as acne and it also speeds up the body's natural wound healing capabilities [3-6]. Zinc is added to skin care products and a zinc deficiency is associated with oxidative stress-induced aging due to free radicals and oxygen reactive species, which are skin-damaging particles that zinc targets .
Tyrosine, an amino acid found in the body, plays its role in the skin by helping to produce melanin .
Camellia sinensis leaf (Green tea) contains antioxidants such as epigallocatechin-3-gallate (EGCG) which combat UV-induced DNA damage .
Anti-aging [1, 2], skin firming, moisturizing, brightening, and blemish reduction [1-5], targets fine lines, wrinkles, and discoloration [1, 2]
Vitamin C (L-ascorbic acid) supports healthy levels of inflammation, has skin-smoothing properties, supports healthy levels of collagen as well as photoreceptor enhancing properties, particularly when it is formulated with vitamin E and ferulic acid [1, 2]. Vitamin C also helps reduce the appearance of fine wrinkles and skin discoloration [1, 2].
Zinc supports skin health by promoting detoxification and it also has anti-inflammatory properties that heighten the body's natural wound healing process [3-6]. Zinc is frequently added to skin care products because it targets free radicals and prevents them from damaging fibroblasts (skin cells) and lipids (fats) that play a role in protecting the skin from UV exposure or skin irritants (e.g., pollution) . Zinc is also linked to anti-aging due to its ability to protect collagen-producing fibroblasts and lipids in the skin .
Tyrosine is associated with balanced collagen and skin pigmentation .
Camellia sinensis leaf extract (green tea) contains EGCG, which is an antioxidant that targets oxidative stress-induced skin damage .
