We recommend to use up this product quickly after opening: Ascorbic Acid degrades fast when it gets in contact with air and light. The moment the product turns orange, it is a sign that a significant share of the vitamin C in it is no longer effective.
- Humectants (sodium hyaluronate 1.20% - 1.80%, glycerin 3.70% - 5.60% and galactoarabinan 0.35% - 0.75%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: ferulic acid.
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 can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic acid.
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.
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.

Moisturizing
What does the product description say?
Harnessing L-ascorbic acid (the purest form of antioxidant vitamin C) and moisturising hyaluronic acid (in three different molecular sizes to penetrate different layers of your skin), these ingredients complement each other to visibly improve tone, texture, hydration and firmness.

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": galactoarabinan, glycerin.
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).
