Moisturizers work through three kinds of ingredients: humectants, emollients, and occlusives. Knowing the difference makes choosing products much clearer.
What is the difference between humectants, emollients, and occlusives?
Humectants attract and hold water, emollients soften and smooth the surface, and occlusives form a layer that helps slow water loss. Most good moisturizers combine all three, which is why they hydrate, feel comfortable, and help skin stay hydrated over time.
Which do you need?
Usually a mix. Humectants like hyaluronic acid and glycerin draw in water, emollients like squalane soften, and occlusives seal it in. A well-formulated moisturizer such as the Rich Moist Soothing Cream covers all three, and our hyaluronic acid guide explains the humectant part.
How do you layer them?
Apply water-loving humectant steps first, ideally on damp skin, then seal with a moisturizer that supplies emollients and occlusives. This order helps the water you layered stay put rather than evaporating.

The three jobs of a moisturizer
