Glycerin vs Hyaluronic Acid
Which is right for your skin?
Both are humectants. Glycerin is the time-tested, any-climate workhorse; hyaluronic acid holds more water but can feel tight in very dry air. Glycerin is the safer everyday pick; many products use both.
A workhorse hydrator that pulls water into your skin. In nearly every good moisturizer for a reason.
A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.
Can you use Glycerin and Hyaluronic Acid together?
