Works for
Anti-agingLactic acidMay help
“The abundantly blended beauty ingredients moisturize the skin and make fine wrinkles due to dryness less noticeable.”
This product contains lactic acid. 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.
MoisturizingSucrose, Yeast extract + 7 moreWorks
“Brand from Japan Tofu Moritaya. Naturally derived moisturizing ingredients such as flower yeast extract, Suizenji nori polysaccharide, and soymilk-derived lactic acid bacillus / soymilk fermented liquid are blended.”
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, hydrolyzed hyaluronic 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: squalane.
Evens skin toneSide benefit · Lactic acid, Yeast extractWorks well
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: lactic acid
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: yeast extract.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
ExfoliationSide benefit · Lactic acidWorks well
This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: lactic acid.
Anti-oxidationSide benefit · Yeast extractMay help
This product contains antioxidants (yeast extract) 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.

Ingredient callouts
- This product contains acids (lactic acid 2.10% - 3.20%). Their concentration is low, and they will not have a strong exfoliating effect. Instead, they work to support the skin natural acid mantle and to attract water (as humectants). Lactic acid is particularly good in attracting water to the upper layer of the skin and improving the skin barrier.
- Humectants (trehalose 0.45% - 1.00%, hydrolyzed hyaluronic acid 1.00% - 1.50%, lactic acid 2.10% - 3.20%, glycerin 3.30% - 5.00%, yeast extract 11.00% - 16.00% and sucrose 26.00% - 39.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
