What the product description says
“Nourishes dehydrated skin cells while hydrates and soothes skin at the same time.”
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: glycerin, mannitol.

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: phytosphingosine, cetearyl alcohol.

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

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.

Concentration of 4-6% is better for helping with acne and balancing the sebum production~1.4–2.1%

What the product description says
“A premium anti-aging essence contains Korean ginseng, nourishes your skin while promoting a radiant complexion.”
Source: Yesstyle

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.

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.

Product summary

"HANYUL - Geuk Jin Water" is effective for: Anti-aging, Moisturizing, Evens skin tone and Anti-blemish

Ingredient callouts

  • A good concentration of Niacinamide (1.40% - 2.10%). Niacinamide is a well-studied multi-tasking active. 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 improve the skin tone, reducing pigmentation marks.
  • Ceramides (phytosphingosine 0.10% - 0.40%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
  • Adenosine 0.10% - 0.30%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
  • Humectants (mannitol 0.40% - 0.95% and glycerin 4.30% - 6.50%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
