Kate Ryan Skincare Vitamin C Daytime Repair Serum

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide, tetrahexyldecyl ascorbate.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: carnosine, centella asiatica extract, ferulic acid, phloretin, resveratrol.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": carnosine, hyaluronic acid.

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).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

This product might be able to help reduce blemishes and clogged pores because it contains niacinamide.

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glutathione, niacinamide, tetrahexyldecyl ascorbate

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: ferulic acid, phloretin, resveratrol, tetrahydrobisdemethoxydiferuloylmethane, tetrahydrodemethoxydiferuloylmethane, tetrahydrodiferuloylmethane.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

This product contains antioxidants (carnosine, ferulic acid, glutathione, lycopene, phloretin, resveratrol, superoxide dismutase, tetrahexyldecyl ascorbate, thioctic acid, ubiquinone) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - camellia sinensis leaf extract, centella asiatica extract, tetrahydrobisdemethoxydiferuloylmethane, tetrahydrodemethoxydiferuloylmethane, tetrahydrodiferuloylmethane also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
