Exfoliation

Hydroxyethyl urea, Sea salt

What the product description says

“Also packed with yeast extract, arbutin, aloe, sugar maple and sugar cane extract to soothe and hydrate skin.”

Source: Yesstyle

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: hydroxyethyl urea.

Hydroxyethyl ureaKey activeEffect: HighA derivative of urea, a compound that is naturally present in skin. Attracts water to the upper layer of the skin. Can enhance penetration of other ingredients~0.95–1.15%

Sea saltEffect: Low, below effective doseUsed to thicken the product formulation and might help to add minerals to the surface of the skin. It is used in scrubs as a physical exfoliant. Can increase sensitivity to other ingredients if left on the skin or used in high concentration~0.05–0.15%

What the product description says

“Also packed with yeast extract, arbutin, aloe, sugar maple and sugar cane extract to soothe and hydrate skin.”

Source: Yesstyle

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: algae extract, 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: algae extract, glycosphingolipids.

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%

Hydroxyethyl ureaKey active· HumectantEffect: HighA derivative of urea, a compound that is naturally present in skin. Attracts water to the upper layer of the skin. Can enhance penetration of other ingredients~0.95–1.15%

Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.55–0.85%

Sodium lactateKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product~0.4–0.65%

Polyglycerin-3Key active· HumectantEffect: HighHelps to attract water to the upper layer of the skin~0.3–0.55%

Hydrolyzed collagenKey active· Humectant, EmollientEffect: HighA typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin~0.3–0.55%

Glyceryl glucosideKey active· HumectantEffect: HighCan help to restore skin barrier function and soften its upper layer~0.25–0.45%

GlycosphingolipidsKey active· EmollientEffect: HighA type of lipids naturally present in skin. They can be converted to ceramides in skin~0.25–0.5%

Hydrolyzed rice proteinKey active· HumectantEffect: MediumHelps attract water to the upper layer of the skin. Might have some anti-oxidant properties~0.25–0.45%

Polyglutamic acidKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin.~0.2–0.4%

Algae extractKey active· Humectant, EmollientEffect: HighPlant extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but research is not extensive yet~0.2–0.35%

Hydrolyzed yeast extractKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin and might have some anti-oxidant and skin lightening properties~0.2–0.4%

Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~3.9–4.7%

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~3–3.6%

Hydrolyzed conchiolin proteinEffect: Low~0.25–0.45%

Magnesium gluconateEffect: LowA mineral that might be able to support skin hydration, but convincing research on its effectiveness in topical skincare is lacking~0.15–0.25%

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~1.4–1.7%

LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.25–0.45%

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~0.45–0.65%

Anti-oxidation

Not advertised by the brand · Arbutin, Glycyrrhiza glabra root extract + 3 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~0.05–0.1%

Glycyrrhiza glabra root extractEffect: LowA plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals~1.6–2%

Hydrolyzed rice proteinEffect: LowHelps attract water to the upper layer of the skin. Might have some anti-oxidant properties~0.25–0.45%

Hydrolyzed yeast extractEffect: LowHelps attract water to the upper layer of the skin and might have some anti-oxidant and skin lightening properties~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%

Evens skin tone

Not advertised by the brand · Arbutin, Glycyrrhiza glabra root extract + 2 more

May help

This product might be able to help reduce hyperpigmentation and even out the skin tone because it contains hydroxyethyl urea. The effect, if any, is likely to be small. Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

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

Glycyrrhiza glabra root extractEffect: LowA plant extract that can help lighten the skin and calm down inflammation. Might be helpful in neutralizing free radicals~1.6–2%

Hydrolyzed yeast extractEffect: LowHelps attract water to the upper layer of the skin and might have some anti-oxidant and skin lightening properties~0.2–0.4%

Dipotassium glycyrrhizateEffect: Low, below effective doseA 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~0.45–0.65%
