Classify the moisturizers according to the mechanism of action of their components.

Oclusives retard the evaporation and epidermal loss of water by forming a hydrophobic film on the skin surface and in the space between the superficial keratinocytes.
Humectants retain water from the formulation, the atmosphere, and attract water present in the dermis, retaining it in the stratum corneum and thus preventing its evaporation.
Film-forming humectants form a hydrophilic film on the stratum corneum, increasing water retention on the skin surface.
Hyaluronic acid is present in most moisturizing cosmetics and is very important for maintaining natural hydration and collagen in the skin, resulting in firmer, better hydrated, and younger-looking skin.
Emollients have the ability to fill spaces, better retaining water with the aid of the occlusive capacity of the stratum corneum.
