What the product description says
“anti-aging and hydrating effects”
Source: Lookfantastic US

This product contains retinyl palmitate, serine. There is some human evidence that these ingredients help reduce and prevent fine lines and wrinkles and improve skin elasticity and firmness, though it is smaller or less consistent than the evidence for the best anti-aging ingredients.

SerineKey activeEffect: MediumAn amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles~1.1–1.7%
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~0.4–0.9%
Hyaluronic acidEffect: LowOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation~0.35–0.75%
Aloe barbadensis leaf juiceEffect: Low, below effective doseTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~0.9–1.4%
Ascorbyl tetraisopalmitateUnder-dosedA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.5–1.2%

What the product description says
“intense hydration activating complex”
Source: Lookfantastic US

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: biosaccharide gum-1, 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: squalane, caprylyl glycol.

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.~5.2–7.9%
Imperata cylindrica root extractKey active· HumectantEffect: HighA plat extract that might help neutralize free radicals in skin and attract water to its upper layer~2.8–4.3%
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~2.2–3.3%
Sodium pcaKey active· HumectantEffect: HighNaturally present in skin and helps to attract water to its upper layer~1.5–2.3%
SerineKey activeEffect: HighAn amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles~1.1–1.7%
Biosaccharide gum-1Key active· HumectantEffect: HighHelps attract water to the upper layer of the skin and is claimed to provide a longer-lasting hydration because of its ability to create a water-binding film on the surface of the skin~0.4–0.9%
Hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation~0.35–0.75%
Rosa damascena flower oilEffect: LowUsed as a fragrance. Can be irritating~0.2–0.7%
Isohexadecane· EmollientEffect: LowImproves the texture of the product and helps soften the skin. Helps oil and water mix together and can be used as a cleansing agent~0.1–0.45%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.05–0.3%
Aloe barbadensis leaf juiceEffect: Low, below effective doseTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~0.9–1.4%

Anti-oxidation
Side benefit · Imperata cylindrica root extract, Tocopheryl acetate + 1 more
May help

This product contains antioxidants (imperata cylindrica root extract) that can help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is some human evidence for this effect in skin, though it is smaller or less consistent than the evidence for the best antioxidants.

Imperata cylindrica root extractKey activeEffect: MediumA plat extract that might help neutralize free radicals in skin and attract water to its upper layer~2.8–4.3%
Tocopheryl acetateEffect: LowA more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.~0.6–1.35%
Ascorbyl tetraisopalmitateUnder-dosedA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.5–1.2%
