What the product description says
“SEKKISEI Cream Excellent is a highly potent cream, containing seven Asian botanical ingredients to hydrate, brighten the complexion, and revitalize the skin to improve aging skin conditions.”
Source: SkincareRX

This product contains ascorbyl glucoside. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Ascorbyl glucosideKey activeEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.2–1.5%
Limnanthes alba seed oilEffect: LowThis oil's cmposition is closest to rapeseed oil. It is a very stable oil and serves as an emoillient~4.4–5.4%

What the product description says
“Revitalizes, brightens and hydrates.”
Source: SkincareRX

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, butylene glycol.

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: dimethicone, squalane.

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~0.15–0.3%
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~3.1–3.8%
Limnanthes alba seed oilKey active· EmollientEffect: HighThis oil's cmposition is closest to rapeseed oil. It is a very stable oil and serves as an emoillient~4.4–5.4%
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.~2.5–3%
Cetyl palmitateKey active· EmollientEffect: MediumAn emollient that helps soften the skin and is used to improve product texture and stability~0.7–1.1%
Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~1.7–2%
Behenyl alcohol· Emollient, OcclusiveEffect: LowNon-drying alcohol that helps water and oil mix together. Also serves as an emollient~1–1.2%
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~6.5–7.9%

This product contains antioxidants (ascorbyl glucoside) 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.

Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~1.2–1.5%
