The Skincare Benefits of Humectants — Plus, How to Use Them in the Winter
October 03, 2023
Alongside occlusives and emollients, humectants are one of the three major types of moisturizing ingredients. Even if you don’t exactly know what a humectant is, you’ve likely already used one in your skincare routine. Do hyaluronic acid, glycerin or aloe vera ring any bells?
“A humectant is a water-attracting ingredient used in skincare to draw moisture to the skin,” says Dr. Blair Murphy-Rose, a board-certified dermatologist based in New York City. She explains that humectants can get this moisture from deeper layers of the skin or from your surrounding environment, which is why the ingredient category can be especially beneficial during the summer when it’s more humid.
But what happens during the colder months when your skin is dehydrated and the air lacks humidity — are humectants still useful? Ahead, Dr. Murphy-Rose breaks down how to get the most out of humectants in drier climates and seasons.
How Humectants Work
“By applying a humectant to the dehydrated outermost layer of skin, the stratum corneum, we can pull water from the environment and the deeper skin layers, and then redirect it to the stratum corneum where we want it,” says Dr. Murphy-Rose.
One of the most common humectants is hyaluronic acid, which is one of Dr. Murphy-Rose’s favorite skincare ingredients. Other humectants often found in skincare products include glycerin, propylene glycol and vitamin B5 or panthenol. Aloe vera, honey and lactic acid all have humectant properties as well.
How to Get the Most Out of Humectants in the Winter
Even when your skin and the environment are dry, humectants will still work. They may just need a little help to give you the best results.
“It’s important to keep your body well-hydrated by drinking adequate fluids, especially in drier climates,” says Dr. Murphy-Rose. “Another good tip for using a humectant in the winter is to apply it in the bathroom right after showering when there is still a good amount of moisture and steam present.”
No matter the season, she says that a moisturizing product that contains a combination of humectants, occlusives and emollients will be most effective. Together, these ingredients can help to replenish moisture, seal it in and soften your skin.
