What the product description says
“It reduces wrinkles, evens out the color and supports the fight against acne.”
Source: N/A

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

Ascorbic acidHeroEffect: HighThe 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~6.8–10.3%
Prunus amygdalus dulcis oilEffect: LowAn emollient that softens the skin~2.1–3.1%
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~1.4–2%
Ascorbyl glucosideUnder-dosedA 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~0.9–1.35%
Evens skin tone
Side benefit · Ascorbic acid, Ascorbyl glucoside
Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic 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
Side benefit · Coco-caprylate/caprate, Prunus amygdalus dulcis oil + 2 more
Works

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