Based on the ingredient list, "Kikumasamune - Sake Skin Care Lotion High Moisture" can work well for skin moisturization. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Kikumasamune - Sake Skin Care Lotion High Moisture ticks this box. Arginine, glutamic acid, glycerin, maltitol and butylene glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (ceramide 3, ceramide 6 ii and arginine) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
Ingredient callouts
Another benefit is that this moisturizer contain ceramides (ceramide 6 ii 1.00% - 1.50% and ceramide 3 1.30% - 1.90%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.

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:
arginine, glutamic acid.
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:
arginine.
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: ceramide 3, ceramide 6 ii
A type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin
Beta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin
Anti-oxidation
This product contains antioxidants (arbutin) 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.
Beta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin
