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: glycerin, inositol.

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: beeswax, cera alba.

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~2.1–2.6%
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~4.9–6%
BeeswaxKey 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~1–1.2%
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~1.4–1.7%
Myristyl myristateKey active· Emollient, OcclusiveEffect: HighAn emollient. Is not recommended for acne-prone skin as it can be comedogenic~1.8–2.2%
Chondrus crispus extractKey active· OcclusiveEffect: HighRed algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency~0.5–0.7%
InositolKey active· HumectantEffect: High~0.7–1.05%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.45–0.65%
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.~2.7–3.3%
Glyceryl stearate seKey activeEffect: MediumUsed to stabilize the product formulations and works as an emollient~1.3–1.6%
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~28–35%
SericinKey activeEffect: Medium~0.45–0.7%
Hydrolyzed silkKey active· HumectantEffect: MediumCan help attract water to the upper layer of the skin~0.5–0.75%
Whey protein· EmollientEffect: LowA protein derived from milk. In skincare products, might help to soften the upper layer of the skin~0.7–1%
Behenyl alcohol· Emollient, OcclusiveEffect: LowNon-drying alcohol that helps water and oil mix together. Also serves as an emollient~1.9–2.3%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~0.3–0.55%
Caprylic/capric/myristic/stearic triglyceride· EmollientEffect: LowHelps to soften the upper layer of the skin~0.6–0.9%
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~0.6–0.95%
GluconolactoneUnder-dosedEffect: HighA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~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%

Well-moisturized skin might also be able to repair the sun damage better.This ingredient - camellia sinensis leaf extract - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

This ingredient camellia sinensis leaf extract might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.
