Product Summary
"Circadia - Vitamin C Reversal Serum" is effective for: Moisturizing
Ingredient callouts
- An effective concentration of Panthenol (pro-vitamin B5) - about 1.40% - 2.10%. Panthenol helps strengthen the skin barrier, improve hydration and reduce inflammation in skin.
- Humectants (panthenol 1.40% - 2.10% and sodium hyaluronate 3.60% - 5.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Moisturizing
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": sodium hyaluronate, caprylyl glycol.
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: panthenol

Anti-aging
This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - magnesium ascorbyl phosphate - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
A derivative of vitamin C that is more stable, but less bioavailable than the pure form of vitamin C. It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin. It can be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high
