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: sodium hyaluronate, saccharomyces/rice ferment filtrate.

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: cera alba, squalane.

Oryza sativa bran oilKey active· EmollientEffect: HighHelps soften the upper layer of the skin and might have some anti-oxidant properties~3.3–5%

Cera albaKey active· Emollient, OcclusiveEffect: HighForms a protective barrier that holds water and keeps dry skin hydrated. Keeps an emulsion from separating into its oil and liquid components, and increases the thickness of a product. Can be an allergen~3.3–5%

Helianthus annuus seed waxKey active· EmollientEffect: HighHelps soften the upper layer of the skin and support skin's barrier function while creating a thicker product consistency~5.4–8%

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.~25–38%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.6–1.35%

Saccharomyces/rice ferment filtrateKey active· HumectantEffect: MediumA product of yeast fermentation. Can contain humectants that help attract water to the upper layer of the skin and might help neutralize free oxidants~2.2–3.2%

Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.35–0.85%

Camellia sinensis leaf extractEffect: LowCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~1.5–2.3%

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~0.45–1.05%

Moderate support

This product contains antioxidants (camellia sinensis leaf extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
