Hyaluronic Acid: What It Does in a Skincare Routine

Hyaluronic acid (HA) is a humectant ingredient used in many facial serums. On skin, humectants help support a hydrated-looking surface when used with moisturizer. Where it sits in a routine Cleanse → HA serum → moisturizer. Applying serum to lightly damp skin is a common approach. What to expect Look for skin that appears more hydrated and feels less tight — not overnight “transformation” promises. Results vary by formula, climate, and the rest of your routine.
