What the product description says
“The unique formulation contains a high concentration of pure hyaluronic acid, proxylane TM, and botanical extracts of licorice root and purple rice to support the skin's own hyaluronic acid levels while also delivering surface hydration and helping improve the appearance of firmness, smoothness, and facial plumpness.”

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: dipotassium glycyrrhizate, 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: dimethicone, caprylyl glycol.

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~4.1–5.1%
Hydroxypropyl tetrahydropyrantriolKey activeEffect: HighA sugar-derived compound that helps to attract water to the upper layer of the skin and might be able to stimulate synthesis of skin's own moisturizing factors, but solid research is lacking. It could be irritating~2.4–2.9%
Dipotassium glycyrrhizateKey active· HumectantEffect: HighA salt derived from licorice. Works as an emollient to soften the upper layer of the skin and can help calm down inflammation. Might be helpful for skin lightening~1.7–2.1%
PolymethylsilsesquioxaneKey activeEffect: HighA silicone that improves product texture and helps dissolve other ingredients. Can form a non-greasy film on the skin to prevent moisture loss~1.2–1.5%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.95–1.15%
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~0.75–1.1%
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)~0.25–0.45%
Cyclohexasiloxane· EmollientEffect: LowA silicone that serves as an emollient. Helps create a nice non-greasy feels~7.1–8.7%
Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~2–2.4%
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~1.5–1.9%
Octyldodecanol· EmollientEffect: LowAn emollient that helps to soften the skin and create a pleasant product texture and stabilize the formulation~0.45–0.7%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.35–0.65%
Dextrin· HumectantEffect: LowA sugar that is used to stabilize the product formulation. Can help attract water to the upper layer of the skin~0.3–0.55%
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~0.05–0.15%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.55–0.85%
Oryza sativa extractEffect: Low, below effective doseA grain extract that helps to create a thicker product consistency. It might have some anti-oxidant properties and help attract water to the upper layer of the skin~0.3–0.5%
Caprylic/capric triglycerideUnder-dosedA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~0.3–0.55%
Exfoliation
Side benefit · Capryloyl salicylic acid
Works well

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: capryloyl salicylic acid.

Capryloyl salicylic acidKey activeEffect: High~0.45–0.7%
Anti-aging
Side benefit · Adenosine, Tocopherol
Works well

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)~0.25–0.45%
TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.55–0.85%
Evens skin tone
Side benefit · Capryloyl salicylic acid, Dipotassium glycyrrhizate
May help

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

Capryloyl salicylic acidKey activeEffect: Medium~0.45–0.7%
Dipotassium glycyrrhizateEffect: LowA salt derived from licorice. Works as an emollient to soften the upper layer of the skin and can help calm down inflammation. Might be helpful for skin lightening~1.7–2.1%

Ingredient callouts

  • Adenosine 0.25% - 0.45%. 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).
  • Dipotassium Glycyrrhizate in this product (1.70% - 2.10%) can also further help improve the skin barrier. It might be able to calm down inflammation and reduce sensitivity. Dipotassium Glycyrrhizate is an active compound from the licorice root.
  • Humectants (sodium hyaluronate 0.95% - 1.15%, glycerin 4.10% - 5.10% and dipotassium glycyrrhizate 1.70% - 2.10%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
