What the product description says
“Infused with a hydrating blend of Cocoa Butter, Sweet Almond Oil and Macadamia Nut, the rich moisturiser melts in effortlessly to replenish moisture and support natural collagen production for a smoother and tighter appearance.”

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 lactate.

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: dimethicone, theobroma cacao seed butter.

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

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~0.45–0.65%
SerineKey activeEffect: HighAn amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles~0.25–0.45%
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~0.25–0.5%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA 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~1.5–1.9%
UreaHero· HumectantEffect: HighNaturally 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~0.2–0.4%
Prunus amygdalus dulcis seedKey activeEffect: HighHelps soften the upper layer of the skin~0.45–0.7%
Theobroma cacao seed butterKey active· EmollientEffect: HighHelps soften the upper layer of the skin and can be helpful in restoring the skin barrier function. Might have some anti-oxidant effect~0.25–0.5%
Glyceryl stearate seKey activeEffect: MediumUsed to stabilize the product formulations and works as an emollient~1.9–2.4%
Cetyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together~2.5–3%
Macadamia ternifolia seed oilKey active· EmollientEffect: MediumPlant oil from nuts that helps soften the upper layer of the skin. Contains a high concentration of oleic acid that can weaken skin's barrier function and increase water-loss while enhancing penetration of other ingredients~0.35–0.6%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.65–0.95%
Ethylhexyl stearate· EmollientEffect: LowHelps soften the upper layer of the skin~4.1–5%
Isopropyl palmitate· EmollientEffect: LowHelps soften the upper layer of the skin and create a thicker product consistency~2.3–2.8%
Propylene glycol· HumectantEffect: LowHelps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating~5.2–6.3%
Sorbitol· HumectantEffect: LowHelps attract water to the upper layer of the skin and improves the product texture~0.25–0.45%
Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.55–0.8%
Lactic acidUnder-dosedEffect: HighAn 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)~0.3–0.55%
Butyrospermum parkii butterUnder-dosedEffect: HighA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~0.4–0.6%
AllantoinUnder-dosedEffect: HighHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.05–0.1%

Product summary

"Sanctuary Spa - Youth Boosting Body Butter" has a good moisturizing formula. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Urea, glycerin, sodium lactate, caprylyl glycol and sorbitol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (theobroma cacao seed butter, dimethicone, cetyl alcohol, macadamia ternifolia seed oil and prunus amygdalus dulcis oil) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Irritation risk

There are quite a few common irritants in this product, including ingredients without particular skin benefits. We would not recommend it for sensitive skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here
