What the product description says
“This gel-cream mask, with delicate floral aromas, provides immediate and long-term deep hydration.”
Source: Skinstore

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, imperata cylindrica root extract.

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: simmondsia chinensis seed oil, jojoba esters.

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~4.4–5.4%
Simmondsia chinensis seed oilKey active· Emollient, OcclusiveEffect: HighSoftens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.~4.2–5.1%
Jojoba estersKey active· EmollientEffect: HighAn emollient made of jojoba oil. Helps soften the skin and support its barrier function~3.1–3.8%
Imperata cylindrica root extractKey active· HumectantEffect: HighA plat extract that might help neutralize free radicals in skin and attract water to its upper layer~1.1–1.4%
Sodium pcaKey active· HumectantEffect: HighNaturally present in skin and helps to attract water to its upper layer~0.4–0.65%
Isononyl isononanoate· Emollient, OcclusiveEffect: LowForms a protective film on the surface of the skin to prevent moisture loss. Gives a velvety feel to products while reducing tackiness~2.4–2.9%
Rosa damascena flower oilEffect: LowUsed as a fragrance. Can be irritating~0.4–0.6%
Isohexadecane· EmollientEffect: LowImproves the texture of the product and helps soften the skin. Helps oil and water mix together and can be used as a cleansing agent~0.35–0.65%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.3–0.5%
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~0.25–0.45%
Aloe barbadensis leaf juiceEffect: Low, below effective doseTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~0.65–1%
Ascorbyl tetraisopalmitateEffect: Low, below effective doseA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.3–0.6%

What the product description says
“Leaves skin smoother, softer and more youthful. Helps to fight off free radical damage. Recommended for dry skin types.”
Source: Skinstore

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.

This ingredient imperata cylindrica root extract might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.

Aloe barbadensis leaf juiceEffect: Low, below effective doseTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin~0.65–1%
Retinyl palmitateUnder-dosedThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.3–0.55%

May help

This product contains antioxidants (imperata cylindrica root 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.

Product summary

"Yon-Ka Paris Skincare - Masque No 1" could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • this product includes a form of Retinoids (vitamin A) - retinyl palmitate 0.30% - 0.55%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
  • Humectants (glycerin 4.40% - 5.40%, sodium pca 0.40% - 0.65% and imperata cylindrica root extract 1.10% - 1.40%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Price

The product retails for 78.00$ in the United States.
