MoisturizingUrea, Galactomyces ferment filtrate + 12 moreWorks well
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": galactomyces ferment filtrate, glutamic acid.
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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: urea
Evens skin toneGalactomyces ferment filtrate, Gluconolactone + 1 moreMay help
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: galactomyces ferment filtrate.
Anti-agingGalactomyces ferment filtrate, Lysine + 2 moreMay help
This product contains galactomyces ferment filtrate, lysine. 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.
Anti-oxidationSide benefit · Galactomyces ferment filtrate, GluconolactoneWorks well
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).

Galactomyces ferment filtrate~3.5–5.2%
- Irritation risk
- Low
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

A polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals

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.

Ingredient callouts
- This product contains acids (gluconolactone 0.15% - 0.70% and lactic acid 0.10% - 0.50%). 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). PHAs (gluconolactone) especially are great for improving skin hydration. They might be even able to stimulate the production of skin's natural humectants and support the healthy skin microbiome.
- Humectants (isomalt 0.10% - 0.35%, glutamic acid 0.35% - 0.85%, glycine 0.40% - 0.90%, urea 0.85% - 1.25%, glycerin 1.50% - 2.30%, sodium pca 2.10% - 3.10% and pitera 3.50% - 5.20%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
