Ingredient callouts
- This product also contains Vitamin C (Ascorbic Acid) 5.40% - 8.00% It can be helpful in stimulating collagen production, neutralizing free radicals in skin and improving pigmentation marks. 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 0.40% - 0.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
Multi-talented, this ingredient also supports the skin’s natural regeneration processes, such as Collagen synthesis.
Source: Lookfantastic
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: ascorbyl glucoside.
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.
The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging
A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products
Anti-oxidation
This product contains antioxidants (ascorbic acid) 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 - ascorbyl glucoside also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Evens skin tone
What does the product description say?
Rich in brightening pigments, Vitamin C works to even out skin tone, targeting dark spots and hyperpigmentation to clarify the complexion.
Source: Lookfantastic
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: ascorbyl glucoside.
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
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": sodium hyaluronate, propylene 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).
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
Helps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating
Helps attract water to the upper layer of the skin and improves the product texture
