Humectant
An ingredient that draws water from the environment and deeper skin layers to hydrate the outer surface of your skin.
A humectant is a category of hydrating ingredient that works by attracting and binding water molecules. Rather than adding oil or creating a seal on the skin's surface, humectants pull moisture from two sources: the humidity in the air around you, and the deeper layers of your own skin. Common humectants you'll see on ingredient lists include hyaluronic acid, glycerin, panthenol, and aloe vera.
In skincare formulations, humectants are typically combined with occlusives (like shea butter or petrolatum) and emollients (like squalane or jojoba oil) to create a balanced moisturiser. This matters because a humectant used alone, particularly in dry or low-humidity environments, can actually draw water out of your deeper skin layers without anything to lock that moisture in place. Well-formulated products account for this by layering these ingredient types together. You'll find humectants in serums, toners, essences, and moisturisers at varying concentrations depending on the product's purpose.
For your routine, humectants are worth considering if your skin feels tight, rough, or generally thirsty regardless of your skin type. They're gentle enough for most people and layer well under other products. A simple approach: apply a humectant-rich serum to slightly damp skin, then follow with a moisturiser that contains occlusive ingredients to help seal that hydration in.
Honest caveat: humectants support hydration, but they won't address concerns like excess oil production, uneven skin tone, or textural changes on their own. They're one piece of a broader routine. If your skin feels persistently dehydrated despite consistent use of well-formulated hydrating products, it's worth speaking to a skincare professional to understand what else might be going on.
