Product Summary
"Tofu Moritaya - Mamehanasui Shakunagehana Yeast Soap" is effective for: Evens skin tone and Exfoliation
This product could be helpful for: Anti-aging and Moisturizing, but its actives are not the most effective or are not well-studied.
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.

Evens skin tone
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.
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
Helps attract water to the upper layer of the skin and might have some anti-oxidant and skin lightening properties. It can help calm down inflammation in skin
Exfoliation
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.

What does the product description say?

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.
An 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.
Can help attract water to the upper layer of the skin. In crystal form, it can work as a gentle exfoliant, gentler than the salt scrub. Helps stabilize the emulsion
A sugar that attracts water to the upper layer of the skin
