What does the product description say?
"Fine Lines and Wrinkles, Dullness and Uneven Texture, Loss of Firmness and Elasticity Formulation."
WIMJ summary

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: ferulic 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.

"Fine Lines and Wrinkles, Dullness and Uneven Texture, Loss of Firmness and Elasticity Formulation."
WIMJ summary

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: dipotassium glycyrrhizate, ferulic acid, glycyrrhiza glabra root extract, lactobacillus/pumpkin ferment extract, tetrahydrobisdemethoxydiferuloylmethane, tetrahydrodemethoxydiferuloylmethane, tetrahydrodiferuloylmethane, vitis vinifera juice 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 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: dipotassium glycyrrhizate, glycerin.

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: chondrus crispus extract, sclerocarya birrea seed oil.

The following ingredients - camellia sinensis leaf extract, tetrahydrobisdemethoxydiferuloylmethane, tetrahydrodemethoxydiferuloylmethane, tetrahydrodiferuloylmethane also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
