The Science of Moisturizers

E

ven though scoping out a good moisturizer may seem confusing, there’s

actually some method to the madness. You can divide moisturizers into

three categories of ingredients based on their function: humectants, emollients,

and occlusives. These three categories work together to fullfill your skin’s

moisturizing needs. Understanding how these ingredients work, and finding a

balance of the categories, is the key to cracking your skin’s moisturizing code.

The reality is that your skin will constantly change.

So, instead of hitting the reset button and tossing

out your current moisturizer—the one that took you

forever to find—figure out which of these categories

you might need just a little more of, and you’ll

master your moisturizing needs through the seasons.

Hopefully, thinking about it in this manner will help you

confidently troubleshoot and adjust your moisturizing

routine when your skin decides to be dramatic.

Category 1: Humectants (The Water Stuff)

Humectants are water-grabbing ingredients that help

your skin maintain a healthy moisture level, which is

key to maintaining that desirable, supple feel. Your

skin naturally has its own water-holding system in the

form of natural moisturizing factors (NMFs), and the

humectants in skincare are there to support them. Some gold-star humectants

used in moisturizers are glycerin, hyaluronic acid, and glycols. Humectants

are so important that many skincare products are humectant-centric, such as

essences, ampoules, hydrating serums, and mists.

Who needs humectants? From the oiliest to the dryest skin, every type can

enjoy the benefits of humectants. They are especially crucial if you want your

dry skin to achieve that supple look!
