Glycerin: The Humble Hydrator That’s in Almost Everything (for Good Reason)
It’s not the trendiest ingredient on the shelf, but Glycerin is a quiet MVP in skincare. You’ll find it in serums, moisturizers, toners, masks — even cleansers. And there’s a reason for that: it works. Simple, effective, and incredibly skin-friendly, Glycerin is all about drawing in moisture and keeping your skin soft, plump, and protected.
What Is Glycerin?
Glycerin is a natural humectant, which means it attracts water — from the air and from deeper layers of your skin — and helps hold it at the surface. It can be derived from plant oils or made synthetically, but no matter the source, its job is the same: hydrate, hydrate, hydrate. It’s one of the most well-tolerated ingredients across all skin types, which is why you’ll find it in nearly every product category.
What Does It Do for the Skin?
Glycerin keeps your skin’s moisture levels balanced. It helps soften rough patches, smooth out texture, and prevent the kind of dehydration that can lead to tightness, flakiness, or irritation. It also supports your skin barrier, helping your face hold onto the hydration you give it — especially in dry weather or after cleansing.

How to Use It
Glycerin is already in a lot of your products — so chances are, you’re using it without realizing. But if you want to maximize its benefits, look for it in hydrating serums or moisturizers and use it on slightly damp skin to help seal in water. It works great both morning and night, and layers beautifully with actives, oils, and barrier-repair ingredients.
Who Should Use Glycerin?
Everyone. Truly. Whether your skin is dry, oily, sensitive, acne-prone, or somewhere in between, Glycerin belongs in your routine. It may not be flashy or high-tech, but it’s reliable, versatile, and deeply good for your skin — which is probably why it’s been used in skincare for over a century.
