Judging from the ingredient list, "La Roche-Posay - Hydraphase Hyaluronic Acid Rich Moisturiser" works well for improving skin hydration To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. La Roche-Posay - Hydraphase Hyaluronic Acid Rich Moisturiser ticks this box. Urea, glycerin, glyceryl acrylate/acrylic acid copolymer, hydrolyzed hyaluronic acid and sodium hyaluronate 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 (beeswax, butyrospermum parkii butter, cera alba, cetyl alcohol and caprylyl glycol) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Hydraphase Hyaluronic Acid Rich Moisturiser

Source: From product name

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, glyceryl acrylate/acrylic acid copolymer.

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: beeswax, butyrospermum parkii butter.

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

butyrospermum parkii butter 2.8% - 4.2%

Irritation risk: Comedogenicity: High

Concentration: Effectiveness: HIGH

A 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

cera alba 1% - 1.5%

Irritation risk:

Concentration: Effectiveness: HIGH

Forms 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

glycerin 4.4% - 6.5%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant

Anti-aging

What does the product description say?

Signs of dehydration include dryness, fatigue and dehydration fine lines.

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.

butyrospermum parkii butter 2.8% - 4.2%

Irritation risk: Comedogenicity: High

Concentration: Effectiveness: LOW

A 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
