Trilogy Trilogy Age Proof Nutrient Plus Firming Serum

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: sodium hyaluronate, aloe barbadensis leaf juice.

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: helianthus annuus seed oil, glycine soja oil.

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 - dipalmitoyl hydroxyproline - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

This product contains ingredients (glycyrrhiza glabra root extract) that could help reduce hyperpigmentation (for example, post-acne marks or age spots) in theory, but there is not enough evidence that they actually work.

This product contains antioxidants (althaea officinalis root extract, dipalmitoyl hydroxyproline, euterpe oleracea fruit oil, glycyrrhiza glabra root extract, oenothera biennis oil). In theory, they could help neutralize free radicals in skin and lessen the damage it gets from the UV light (sun), but there is no evidence that these ingredients can have a noticeable effect in skin.
