Good evidence

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: cocos nucifera oil, helianthus annuus seed oil.

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 BUTTERRole: Under-dosedA 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~0.85–1.25%

CAPRYLIC/CAPRIC TRIGLYCERIDERole: Under-dosedA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~0.55–1.3%

COCOS NUCIFERA OILRole: Key activeAn emollient. Found to be as effective as a moisturizer for dry skin as mineral oil. Could be comedogenic~3–4.5%

HELIANTHUS ANNUUS SEED OILRole: Key activeA 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~0.4–0.9%

RICINUS COMMUNIS SEED OILRole: Key activeA plant oil that can help soften the skin. It might be helpful in calming down inflammation, but solid research is lacking. Is often used in lip products to create the needed product consistency~5.4–8.1%

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.~3.9–5.9%

THEOBROMA CACAO SEED BUTTERRole: Key activeHelps soften the upper layer of the skin and can be helpful in restoring the skin barrier function. Might have some anti-oxidant effect~0.95–1.45%

TOCOPHEROLRole: Under-dosedPure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~1.2–1.8%

LimoneneA common frangrance that can easily irritate skin, especially if exposed to air, light or heatHigh~0.35–0.85%est.

Rosa damascena extractOil of a very fragrant pink rose used as fragrance in cosmetics. Extensive research has shown it has mixed benefits. In the pro column, inhaling this flower’s scent seems to have relaxing properties and the plant’s petals contain skin-soothing and antioxidant compounds that can benefit skin. On the flipside, the numerous chemicals that create this rose’s distinctive fragrance pose a risk of causing skin aggravation.High~0.15–0.65%est.
