Humectant vs Emollient vs Occlusive

Humectant, emollient, and occlusive describe ingredient roles in skin-care formulas. They are not three competing product categories. One lotion or cream can use all three.

Humectants

Humectants attract and hold water in the formula and upper skin layers. Glycerin and hyaluronic acid are common examples.

Emollients

Emollients help smooth the spaces between surface skin cells and improve feel. Plant oils, esters, fatty alcohols, and squalane can act as emollients.

Occlusives

Occlusives form a barrier that slows water loss. Petrolatum is a classic example, while waxes and some oils can provide partial occlusive effects.

How to read a moisturizer

Do not pick a product from one hero ingredient alone. Look at the full ingredient list, texture, fragrance, package, body area, and how the product feels on your skin.

Quick checklist

Use the product label, manufacturer directions, and the specific requirements of your situation. Compare the complete product or system rather than making a decision from one marketing phrase, ingredient, or number.
