The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: aminopropyl ascorbyl phosphate.

Aminopropyl ascorbyl phosphateKey activeEffect: MediumA more stable but less potent derivative of vitamin C. It can help neautralize free radicals and even out the skin tone if used in high enough concentration (required levels are likely to be much higher than for pure vitamin C, and solid studies are lacking at the moment)~2.9–4.4%
Ascorbic acidUnder-dosedThe 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~1.2–1.8%
Moisturizing

What the product description says
“It is multiple separate C-extracts combined into one potent concentrate.”
Source: SmallFlower

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).

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~1.6–2.4%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~1–1.5%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~0.55–1.3%

This product contains aminopropyl ascorbyl phosphate. 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.

It can help neautralize free radicals and even out the skin tone if used in high enough concentration (required levels are likely to be much higher than for pure vitamin C, and solid studies are lacking at the moment)~2.9–4.4%
Sodium ascorbyl phosphateEffect: LowA stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C~7.2–10.8%

This product contains antioxidants (aminopropyl ascorbyl phosphate, sodium ascorbyl phosphate) 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.
