9 ingredients contribute at the levels below

Strong evidence

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, pantolactone.

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: caprylic/capric triglyceride, cera microcristallina.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol, urea

UREARole: Key activeNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~1.1–1.4%

PANTHENOLRole: Key activeHelps attract water to the upper layer of the skin and can help improve skin barrier function~0.65–1%

DIMETHICONERole: Key activeA 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~1–1.2%

GLYCERINRole: Key activeOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~0.55–0.8%

CAPRYLIC/CAPRIC TRIGLYCERIDERole: Key activeA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~4.2–5.2%

PANTOLACTONERole: Key activeHelps attract water to the upper layer of the skin~0.1–0.15%

CERA MICROCRISTALLINARole: Key activeHelps to soften the upper layer of the skin, reduce water loss from its surface and create a thicker product consistency~0.3–0.5%

SIMMONDSIA CHINENSIS SEED OILRole: Key activeSoftens 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.~1.5–1.8%

COLLAGEN AMINO ACIDSRole: Key activeHelp attract water to the upper layer of the skin, soften it and support the skin barrier function~0.15–0.25%

Irritancy

9 flagged ingredients — patch-test recommended

High risk

We flagged 9 ingredients with irritancy potential. Severity depends on your sensitivity threshold; the table lists the worst offenders first.

IngredientFunctionIrritationEst. amount

Propylene glycolHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritatingHigh~0.55–0.8%est.

Retinyl palmitateThree 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 effectHigh~0.2–0.35%est.

Caprylic/capric triglycerideA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerinLow~4.2–5.2%est.

Peg-30 dipolyhydroxystearateHelps oil and water mix togetherLow~2.3–2.8%est.

Simmondsia chinensis seed oilSoftens 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.Low~1.5–1.8%est.

Tocopheryl acetateA 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.Low~0.4–0.6%est.

EthylhexylglycerinA preservativeLow~0.15–0.3%est.

Lactic acidAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)Low~0.1–0.2%est.

BhtA preservativeLow~0.05–0.1%est.

Comedogenic

Decyl oleate ~1.6–2% — rinse-off or low %

Low risk

We flag 1 ingredient with a low-to-moderate comedogenic rating — at these concentrations, or in rinse-off use, they're unlikely to clog pores for most skin.
