What the product description says
“The 9 botanical ingredients of the Jeju Anti-Aging Elixir ComplexTM help address common signs of aging, adding a healthy look to the skin.”
Source: Innisfree

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

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.

AdenosineKey activeEffect: HighMight 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)~0.25–0.5%
Beta-glucanEffect: LowHelps attract water to the upper layer of the skin, calm down inflammation and irritation, restore the barrier function and support wound healing. It can be helpful in reducing fine lines and wrinkles~0.1–0.15%
Camellia sinensis leaf extractEffect: Low, below effective doseCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation~0.25–0.5%
Anti-oxidation
Not advertised by the brand · Arbutin, Adenosine + 10 more
May help

This product contains antioxidants (arbutin) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

ArbutinKey activeEffect: MediumBeta-arbutin. Can help to reduce hyperpigmentation and has an anti-oxidant effect when used in high enough concentration. Is less effective compared to alpha-arbutin~1.7–2.1%
AdenosineEffect: LowMight 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)~0.25–0.5%

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: arbutin.

Moisturizing
Not advertised by the brand · Dimethicone, Cyclopentasiloxane + 10 more
Works

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, butylene glycol.

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: dimethicone, squalane.

DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~5.8–7.1%
CyclopentasiloxaneKey active· EmollientEffect: MediumA silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin~4.4–5.4%
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~2–2.5%
SqualaneKey active· Emollient, OcclusiveEffect: HighAn oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.~1.3–1.6%
PantethineKey active· EmollientEffect: HighHelps to hydrate the skin by improving its barrier funciton~0.6–0.9%
Ganoderma lucidum extractKey activeEffect: HighHelps attract water to the upper layer of the skin~0.25–0.45%
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)~0.25–0.5%
Beta-glucanKey activeEffect: HighHelps attract water to the upper layer of the skin, calm down inflammation and irritation, restore the barrier function and support wound healing. It can be helpful in reducing fine lines and wrinkles~0.1–0.15%
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~3.1–3.8%
Polysilicone-11Effect: LowA silicone that forms a light film on the skin surface helping to bind water and temporarily absorb oils creating a matt and powdery feel~2.4–3%
Dextrin· HumectantEffect: LowA sugar that is used to stabilize the product formulation. Can help attract water to the upper layer of the skin~0.25–0.5%
Camellia sinensis leaf extractEffect: Low, below effective doseCan contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals.

Ingredient callouts

  • Adenosine 0.25% - 0.50%. 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 (glycerin 2.00% - 2.50%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
