Hyaluronic acid (often shortened to “HA”) appears on the labels of serums, moisturisers and even sunscreens. Here is what it is and how to use it.

What is hyaluronic acid?

Hyaluronic acid is a substance your body produces naturally. According to Cleveland Clinic, it is very good at retaining water, which is why it is used in moisturising creams, lotions, ointments and serums.

Who is it for?

  • Dry or tight-feeling skin that needs extra hydration.
  • Oily or combination skin that wants hydration without a heavy cream — most HA serums are light and water-based.
  • Anyone wanting a simple, gentle extra step: Cleveland Clinic notes reactions to hyaluronic acid are rare.

How to use a hyaluronic acid serum

  1. Cleanse gently.
  2. Apply the serum — a few drops, spread over the face.
  3. Moisturise on top to help keep skin comfortable.
  4. Daytime: finish with sunscreen.

Always follow the directions on your product's pack.
