Can the product deliver on its promises?
Promise
What does the product description say?WIMJ summary for anti-aging
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: galactomyces ferment filtrate.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

What does the product description say?WIMJ summary for evens skin tone
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
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: bifida ferment lysate, galactomyces ferment filtrate.
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.

What does the product description say?WIMJ summary for moisturizing
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:
galactomyces ferment filtrate, 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: squalane, caprylyl glycol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, panthenol

WIMJ summary for anti-oxidation
This product contains antioxidants (galactomyces ferment filtrate) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
The following ingredients - bifida ferment lysate also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

A yeast ferment filtrate (also known as Pitera - a trademarked name for the filtrate reserved by the SK-II brand). It helps attract water to the upper layer of the skin, can help neutralize antioxidants and can be helpful in evening out the skin tone. It might be somewhat helpful in preventing premature skin aging but solid evidence is lacking. A small manufacturer study also shows that, when used in high concentrations, it can help reduce sebum production and help against blocked pores
