What the product description says
“Over time, these engraved imperfections appear shallower and expression lines appear erased, as the vitamin F blend works to replenish skin’s moisture barrier and protect it from environmental aggressors.”

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: anhydroxylitol, glycine.

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: caprylic/capric triglyceride, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8

Acetyl hexapeptide-8Hero· HumectantEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.15–0.3%
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.~4.1–5%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~2–2.5%
Macadamia ternifolia seed oilKey active· EmollientEffect: MediumPlant oil from nuts that helps soften the upper layer of the skin. Contains a high concentration of oleic acid that can weaken skin's barrier function and increase water-loss while enhancing penetration of other ingredients~1.7–2.1%
XylitylglucosideKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and repair the skin barrier function~1.5–1.8%
Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~1.1–1.3%
AnhydroxylitolKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and repair the skin barrir function~0.75–1.15%
Hydrolyzed rice proteinKey active· HumectantEffect: MediumHelps attract water to the upper layer of the skin. Might have some anti-oxidant properties~0.4–0.6%
Glycine soja oilKey active· EmollientEffect: HighA good emollient that helps soften the skin and helps repair its barrier function. It can clog pores if used in high concentrations.~0.35–0.6%
Salvia hispanica seed oilKey active· EmollientEffect: HighChia seed oil. Helps to soften the upper layer of the skin and might be helpful in repairing skin barrier~0.35–0.65%
Hydrolyzed sodium hyaluronateKey activeEffect: HighAttracts water into the upper layer of the skin~0.3–0.55%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.3–0.5%
GlycineKey active· HumectantEffect: HighHelps to attract water to the upper layer of the skin and can help restore the skin barrier function~0.3–0.6%

ProlineKey activeEffect: Medium~0.3–0.55%
Hydrogenated polyisobutene· Emollient, OcclusiveEffect: LowUsed to improve the product consistency and soften the upper layer of the skin~3.2–3.9%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.55–0.85%
Linum usitatissimum seed oilEffect: Low~0.3–0.55%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.35–0.6%
Lactic acidUnder-dosedAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.55–0.85%
Zinc gluconateUnder-dosedTypically used to stabilize the product formulations. It is a salt of a polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin. It can help attract water to the upper layer of the skin. Might to be helpful against acne and clogged pores. Could be helpful in neutralizing free radicals, but solid research is missing. Due to the zinc content, might help calm down inflammation in skin~0.3–0.6%
Alaria esculenta extractUnder-dosedWorks as a humectant helping to attract water to the upper layer of the skin and might be effective as an anti-oxidant.~0.3–0.6%

Tetrahexyldecyl ascorbateUnder-dosedBeing a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.~1.2–1.4%
Lactic acidUnder-dosedAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles.
