“Key Ingredients Retinol expedites skin renewal to reduce the appearance of wrinkles and imperfections Sodium Hyaluronate retains moisture deep within skin layers to increase suppleness and elasticity Sodium PCA delivers hydration and boosts skin's natural retention ability”
Source: Skinstore

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: retinyl acetate.

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.

RetinolHeroEffect: HighTwo steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritating~1.2–1.8%

What the product description says
“Refine Moisturiser”
From product name

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: galactoarabinan, 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: dimethicone, helianthus annuus seed oil.

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~3.4–5.2%
GalactoarabinanKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin~1–1.6%

SqualaneKey active· Emollient, OcclusiveEffect: HighAn oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.~0.5–1.15%
Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~0.35–0.75%
Cassia angustifolia seed polysaccharideKey activeEffect: HighHelps attract water to the upper layer of the skin. Is sometimes referred to as "natural" hyaluronic acid (even though hyaluronic acid is not unnatural and is present in human skin)~0.35–0.85%

Evens skin tone

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: retinol.

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.

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover.
