“This triple-action hydrating lotion immediately helps to reduce the signs of dry skin, giving anti-dryness and anti-irritation for 48 hours**.”
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, glycine.
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: butyrospermum parkii butter, cetearyl alcohol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: urea
Anti-aging2 ingredients credited for this claimLimited support
“This triple-action hydrating lotion immediately helps to reduce the signs of dry skin, giving anti-dryness and anti-irritation for 48 hours**.”
This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - butyrospermum parkii butter - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

Product summary
Judging from the ingredient list, "La Roche-Posay - Lipikar Lait Urea 10%" works well for improving skin hydration The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Urea, glycerin, glycine, sodium lactate and caprylyl glycol 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 (butyrospermum parkii butter, cetearyl alcohol, caprylyl glycol, dicaprylyl carbonate and glyceryl stearate) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
