What the product description says
“Working to diminish the appearance of lines and wrinkles, the vitamin C supports natural collagen synthesis, improving skin elasticity and evening out skin tone, whilst boswellic acid relaxes muscles and fights facial fatigue.”
Source: Lookfantastic

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~6.2–9.3%
Magnesium ascorbyl phosphateEffect: Low, below effective doseA 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~0.4–0.9%
Ascorbyl palmitateEffect: Low, below effective doseBeing a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.~0.05–0.2%

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: yeast extract.

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 · Coconut alkanes, Coco-caprylate/caprate + 4 more
Works

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. 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. The following ingredients in this product do the job: glycogen, mannitol.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: helianthus annuus seed oil, coco-caprylate/caprate.

Coconut alkanesKey active· EmollientEffect: MediumAn emollient that helps soften the skin~23–34%
Coco-caprylate/caprateKey active· EmollientEffect: MediumHelps to soften the upper layer of the skin without creating a greasy texture~4.5–6.8%
