What does the product description say?
"With vitamin C from ascorbic acid, to unify skin tone and dispel dullness, whilst stimulating collagen synthesis to leave skin looking plumped and luminous; alongside boswellic acid – renowned for its ability to relax micro-muscular contractions, so fine lines look less obvious – this quick-fix treatment is a bathroom cabinet must-have."
WIMJ summary

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.

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.

WIMJ summary

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

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).

Ingredients by volume

An emollient that helps soften the skin
One of the few well researched potent anti-aging ingredients. When it is able to penetrate the skin in an active state, it is effective against fine lines and wrinkles, helps improve skin elasticity and reduce hyperpigmentation. It acts as a powerful anti-oxidant and stimulates collagen production. The main issue with ascorbic acid is that it is highly unstable, in other words, it is losing its effectivenss quickly when exposed to air and light (if a serum or cream containing ascorbic acid has an orange color, it is a likely that the ingredient has oxidized and is no longer active). In addition, it is water-soluble, meaning that it has difficulty pentrating the skin. It is also quite irritating, and can cause stinging. When used in low concentrations, helps stabilize the product formulation
Helps to soften the upper layer of the skin without creating a greasy texture
