Product Summary

Ingredient callouts
- Ceramides (ceramide ap 0.20% - 0.40%, ceramide np 0.25% - 0.50% and ceramide eop 0.30% - 0.55%). 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.
- Humectants (alanine 0.35% - 0.65%, histidine 0.40% - 0.60%, aspartic acid 1.40% - 1.80%, glycine 1.70% - 2.00%, arginine 1.90% - 2.30%, glutamic acid 2.10% - 2.60% and glycerin 5.40% - 6.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Moisturizing
What does the product description say?
Sake serum made from rice ■Moisturizing serum containing sake (rice fermentation liquid).

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:
alanine, arginine.
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 ap, ceramide eop, ceramide np
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
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Helps to attract water to the upper layer of the skin and can help restore the skin barrier function

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
Anti-aging
This product contains aspartic acid, serine, threonine. These ingredients 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.

A 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
A derivative of vitamin C that is more stable, but less bioavailable than the pure form of vitamin C. It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin. It can be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high
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
