Glycerin: Humectant for Healthy, Hydrated Skin
Glycerin: Humectant for Healthy, Hydrated Skin
Glycerin is one of the most time-tested and dermatologist-approved ingredients in skincare—and for good reason. Known for its remarkable ability to draw moisture into the skin, glycerin (or glycerol) is a powerful humectant that not only hydrates but also helps maintain the skin’s natural barrier. Whether you're dealing with dryness, irritation, or a compromised barrier, glycerin is a clinically trusted ingredient that delivers. Naturally derived from plant oils or produced synthetically, glycerin is safe, gentle, and suitable for all skin types, including sensitive and reactive skin.

Glycerin can be used both morning and night, as part of your base layer for hydration. It's most effective when included in leave-on products such as moisturizers, hydrating serums, and body lotions. Tip: Always follow up with an occlusive or emollient-rich product in very dry conditions to seal in the glycerin-attracted moisture and prevent TEWL.

Final Takeaway

Glycerin may not be a trendy, exotic ingredient—but it is a scientific essential. Clinically proven to hydrate, heal, and protect, it supports the skin on every level: from the surface barrier to the deeper layers where moisture retention and resilience begin.

For skin that feels nourished, soothed, and perfectly hydrated—especially during periods of sensitivity, dryness, or post-treatment recovery—glycerin is your gold-standard go-to.
