What the product description says
“Olive oil is packed with antioxidants and hydrating squalane, making it ideal for skin hydration and repair.”
Source: Skin Inc

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: arginine, diglycerin.

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: arginine, glycine soja seed extract.

What the product description says
“A popular serum choice, Vitamin A helps improve uneven skin tone, tired, dull skin and dark eye circles to make skin more radiant.”
Source: Skin Inc

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: glycine soja seed extract, retinyl palmitate.

Retinyl palmitateKey activeEffect: MediumThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.55–1.3%

This product contains ingredients (retinyl palmitate) that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.
