Product summary
Judging from the ingredient list, "Ishizawa-Lab - Keana Pore Tightening Lotion For Men" works well for improving skin hydration To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Ishizawa-Lab - Keana Pore Tightening Lotion For Men ticks this box. Allantoin, glycerin, hydrolyzed collagen, sodium hyaluronate 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). Hydrolyzed collagen in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
Ingredient callouts
Another benefit is that this moisturizer contain ceramides (glucosyl ceramide 0.95% - 1.40%). 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.
In addition, this moisturizer contains Allantoin (1.60% - 2.40%). Allantoin is helpful in wound-healing and can help restore the skin barrier faster. It might also be able to improve scars, but the evidence is not very strong for this.

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:
allantoin, glycerin.
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:
hydrolyzed collagen.
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: glucosyl ceramide
A typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin
Used 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
