MoisturizingHydroxypalmitoyl sphinganine, Paraffinum liquidum + 14 moreStrong evidence
“BEURRE DE LÈVRES Hydrating and smoothing lip balm Beurre de lèvres, is Biotherm's replumping and smoothing lip balm.”
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, mel.
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: cera alba, cera microcristallina.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: hydroxypalmitoyl sphinganine, paraffinum liquidum

Oil 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.

Product summary
Based on the ingredient list, "BIOTHERM - BEURRE DE LÈVRES" can work well for skin moisturization. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. BIOTHERM - BEURRE DE LÈVRES ticks this box. Humectants in this product (glycerin and mel) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Emollients in this formulation (paraffinum liquidum, cera alba, cera microcristallina, cetyl alcohol and glyceryl linolenate) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
