What the product description says
“A nutrient-rich serum with a mix of concentrated Pitera™ and Hyaluronic acid, it reduces the appearance of wrinkles and roughness to refine skin texture and elasticity.”

This product contains galactomyces ferment filtrate. 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.

Galactomyces ferment filtrateKey activeEffect: MediumA 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~23–34%

What the product description says
“Facial Treatment Repair C is deeply moisturising, leaves skin feeling silky and smooth and improve's the skin's texture.”

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": galactomyces ferment filtrate, glycerin.

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).
