Hyaluronic Acid + Glycerin
Hyaluronic Acid + Glycerin — a hydration duo of hyaluronic acid and glycerin, two humectants that attract and bind water into the skin. Used together they layer complementary moisture-drawing action to help skin feel plumper, softer, and more comfortable.
Key points
- Both are humectants, meaning they pull water into the upper layers of the skin.
- Glycerin is a small, well-studied humectant that also supports the skin barrier, while hyaluronic acid holds large amounts of water.
- Combining them can provide layered, complementary hydration for most skin types.
- Sealing them with a moisturizer helps prevent the drawn-in water from evaporating, especially in dry climates.
- Both are gentle, non-irritating, and compatible with nearly all other actives.
- Applying to slightly damp skin can enhance their hydrating effect.
Frequently asked
Is it worth using both hyaluronic acid and glycerin?
Yes, both are effective humectants that complement each other, and glycerin is one of the most well-studied hydrating ingredients. Using them together can boost and layer hydration.
How do I keep the hydration from evaporating?
Apply them to slightly damp skin and follow with a moisturizer to seal the water in. This is especially helpful in dry or low-humidity environments.
