What it is
Glycerin is one of skincare's most reliable humectants. It is not trendy or flashy, but it appears everywhere: cleansers, toners, essences, creams, masks, and sunscreens.
What it does
It helps draw and hold water in the skin's outer layer, supporting a smoother, more comfortable barrier. Because it is compatible with so many ingredients, it often acts as the quiet hydration base underneath more famous actives.
How to use it
You do not need a dedicated glycerin serum. Look for it in formulas where you want comfort: low-pH cleansers, barrier creams, hydrating toners, and daily moisturizers.
Good to know
Glycerin is broadly well tolerated. At very high levels it can feel sticky, so texture usually depends more on the formula than the ingredient itself.
