Exfoliation

What the product description says

“Potent dual-action flash mask. Malic Acid, Fig and Pumpkin Enzymes deliver multi-dimensional exfoliation for immediate glow.”

Source: Bluemercury

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.

Anti-oxidation

Not advertised by the brand · Ferulic acid, Camellia sinensis leaf extract + 3 more

Works well

This product contains antioxidants (ferulic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

The following ingredients - camellia sinensis leaf extract also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.

Ferulic acidKey activeEffect: HighA potent anti-oxidant that has been shown to be effective in neutralizing free radicals in skin. There seem to have a synergetic effect of ferulic acid, vitamin E and C, meaning that when the ingredients are used together, they enhance each other's ability protect the skin against free radicals. Ferulic acid also helps to stabilize other ingredients - including vitamins C and E. It can help to even out the skin tone. Ferulic acid is approved for use as a sunscreen ingredient in Japan in concentrations up to 10%~0.6–0.9%

Camellia sinensis leaf extractKey activeEffect: MediumCan 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~0.6–0.85%

Hibiscus sabdariffa flower extractEffect: LowA plant extract that can be irritating. It might contain a compound anthocyanin that could be helpful in neutralizing free radicals~0.55–0.8%

Vitis vinifera oilEffect: LowA great emollient that can also have anti-oxidant properties~0.5–0.75%

Phyllanthus emblica fruit extractUnder-dosedA plant extract that might be helpful in neutralizing free radicals and have a skin lightening effect if used in high enough concentrations~0.65–1%

Moisturizing

Not advertised by the brand · Helianthus annuus seed oil, Glycerin + 9 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, sodium hyaluronate.

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: helianthus annuus seed oil, simmondsia chinensis seed oil.

Helianthus annuus seed oilKey active· Emollient, OcclusiveEffect: HighA great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function~5.5–6.8%

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~2.5–3%

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.~0.6–0.95%

Vitis vinifera oilKey activeEffect: HighA great emollient that can also have anti-oxidant properties~0.5–0.75%

Sesamum indicum seed oilKey active· EmollientEffect: HighA good moisturizing plant oil. Due to the high linoleic acid content, it helps soften the upper layer of the skin, reduce water loss and support skin barrier function~0.5–0.75%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.45–0.7%

Glyceryl stearate· EmollientEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~3.1–3.8%

Stearic acid· EmollientEffect: LowHelps oil and water mix together and works as an emollient~2.8–3.4%

Ananas sativus fruit extractEffect: LowA fruit extract that might help to attract water to the upper layer of the skin, but there is no evidence for any other benefits to the skin~0.45–0.65%

Dipotassium glycyrrhizateUnder-dosedA 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~0.3–0.6%
