“The Cortina 2828 Revitalizing Vitamin C Bio-Serum offers daily antioxidant protection against external aggressors and is enriched with emollient and moisturizing ingredients.”
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, sodium hyaluronate.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
Anti-agingAscorbyl glucoside, Aloe barbadensis leaf juiceMay help
“The Cortina 2828 Revitalizing Vitamin C Bio-Serum offers daily antioxidant protection against external aggressors and is enriched with emollient and moisturizing ingredients.”
This product contains ascorbyl glucoside. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.
Evens skin toneAscorbyl glucoside, Salicylic acidMay help
“Its stimulating and brightening Vitamin C complex, combined with its plumping and softening ingredients, helps smooth wrinkles and minimize pigmentation spots for a visibly younger looking complexion.”
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: ascorbyl glucoside.
ExfoliationSalicylic acid ~0.3–0.75%Under-dosed
This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.
Anti-blemishSalicylic acid ~0.3–0.75%Under-dosed
Effective ingredients missing or their concentration is too low.
Anti-oxidationSide benefit · Ascorbyl glucosideMay help
This product contains antioxidants (ascorbyl glucoside) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
