This product can help soften the skin and reduce its moisture loss with emollients and occlusives: beeswax, butyrospermum parkii butter.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

Butyrospermum parkii butterKey active· Emollient, OcclusiveEffect: 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~5.8–8.7%

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~1.3–1.9%
BeeswaxKey active· Emollient, OcclusiveEffect: HighForms a protective barrier that holds water and keeps dry skin hydrated. Keeps an emulsion from separating into its oil and liquid components, and increases the thickness of a product. Can be an allergen~2.7–4%
Cocos nucifera oilKey active· Emollient, OcclusiveEffect: HighAn emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic~22–33%
Oryza sativa bran oilKey active· EmollientEffect: HighHelps soften the upper layer of the skin and might have some anti-oxidant properties~0.95–1.4%
Persea gratissima oilKey active· EmollientEffect: HighAn emollient that helps soften the skin and could be helpful in repairing its barrier function~0.6–1.4%
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~4.7–7.1%

Moderate evidence

This product contains retinyl palmitate. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Retinyl palmitateKey activeEffect: MediumThree 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~0.15–0.65%
Butyrospermum parkii butterEffect: LowA 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~5.8–8.7%
