What the product description says
“An all-in-one cream toner enriched with galactomyces to nourish dehydrated skin.”
Source: Yesstyle

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: helianthus annuus seed oil, argania spinosa kernel oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

Saccharomyces/imperata cylindrica root ferment extractKey active· EmollientEffect: HighYeast extract obtained from a plant root (cogon grass). It works as an excellent humectant attracting water to the upper layer of the skin. Can have some anti-inflammatory effect~0.35–0.8%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~3.7–5.6%
Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~1.1–1.7%
Hydrolyzed hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin~0.2–0.7%
Limnanthes alba seed oilKey active· EmollientEffect: HighThis oil's cmposition is closest to rapeseed oil. It is a very stable oil and serves as an emoillient~0.9–1.35%
NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~1.4–2.2%
Argania spinosa kernel oilKey active· EmollientEffect: HighAn emollient that helps soften the upper layer of the skin. Might have some weak anti-oxidant properties~0.45–1.05%
Galactomyces ferment filtrateKey active· HumectantEffect: HighA 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~5.3–7.9%
AdenosineKey activeEffect: MediumMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.4–0.9%
Canola oilKey active· EmollientEffect: MediumA plant oil that can help soften the upper layer of the skin~1.3–2%
Butylene glycol· HumectantEffect: LowUsed 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~2.7–4.1%
Polyglyceryl-10 stearateEffect: LowHelps water and oil mix together and softens the upper layer of the skin~0.5–1.2%
AllantoinUnder-dosedEffect: HighHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.15–0.55%
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.

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: 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.

Product summary

Judging from the ingredient list, "RiRe - Galactomyces Cream Skin" works well for improving skin hydration The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Humectants in this product (galactomyces ferment filtrate, glycerin, hydrolyzed hyaluronic acid and butylene glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Limnanthes alba seed oil, saccharomyces/imperata cylindrica root ferment extract, helianthus annuus seed oil and canola oil in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

  • We particularly like that there is a good concentration of Niacinamide (1.40% - 2.20%) in this moisturizer. Niacinamide is a well-studied multi-tasking active. It is a great ingredient to have in a moisturizer. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and help improve the skin tone, reducing pigmentation marks.
  • Adenosine 0.40% - 0.90%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: allantoin
