What the product description says

“Treat your skin to a wave of hydration with the Oh K! Jeju Mineral Lava Sea Water Hydrogel Mask.”

Source: Lookfantastic

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: betaine, 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: chondrus crispus extract, glyceryl caprylate.

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~4.7–5.7%

Chondrus crispus extractKey active· OcclusiveEffect: HighRed algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency~2.4–2.9%

BetaineKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~1.9–2.3%

TrehaloseKey active· HumectantEffect: HighA sugar that attracts water to the upper layer of the skin~1.6–2%

Chondrus crispus powderKey activeEffect: MediumA powder from red algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency~1.6–2%

Centella asiatica extractKey activeEffect: HighA plant extract that has been shown to be able to reduce inflammation in skin, support restoration of skin barrier function, as well as support collagen production. Contains active compounds called centelloids: asiaticoside, madecasosside, asiatic acid and madecassic acid. Might be helpful in preventing stretch marks. It can be itself be irritating though.~0.6–0.9%

SucroseKey active· HumectantEffect: HighCan help attract water to the upper layer of the skin. In crystal form, it can work as a gentle exfoliant, gentler than the salt scrub. Helps stabilize the emulsion~0.25–0.5%

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)~0.2–0.4%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.05–0.15%

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~1.2–1.5%

Glyceryl caprylate· EmollientEffect: LowAn emollient that can also help water and oil mix together, as well as prevent bacteria growth in products~0.4–0.65%

AlginEffect: LowUsed to thicken product formulation. Can help attract water to the upper layer of the skin~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~0.2–0.4%

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~0.15–0.25%

Anti-aging

Side benefit · Centella asiatica extract, Adenosine + 1 more

Works well

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: centella asiatica extract.

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.

Anti-oxidation

Side benefit · Centella asiatica extract, Paeonia suffruticosa root extract + 4 more

May help

This product contains antioxidants (centella asiatica extract) 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.

Paeonia suffruticosa root extractEffect: Low~0.95–1.2%

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)~0.2–0.4%

Tocopheryl acetateEffect: Low, below effective doseA more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.~0.2–0.35%

Ingredient callouts

Adenosine 0.20% - 0.40%. 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).
Humectants (sodium hyaluronate 0.10% - 0.15%, sucrose 0.25% - 0.45%, trehalose 1.60% - 2.00%, glycerin 4.70% - 5.70% and betaine 1.90% - 2.30%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
