Hyaluronic Acid: The Hydration Hero, Explained

What hyaluronic acid does

Hyaluronic acid (HA) is a humectant — it draws water into the skin, helping it look plumper, smoother and more hydrated. It occurs naturally in the body and suits every skin type, including oily and sensitive.

Why it's so popular

• Lightweight hydration that doesn't feel greasy.
• Helps skin look plumper and softer.
• Pairs well with almost any other ingredient.

How to use it

Apply an HA serum to slightly damp skin, then lock it in with a moisturiser. This helps it hold onto water rather than pulling it from deeper layers in dry air. Use it morning and night, before your cream.

A tip for dry climates

In very dry or air-conditioned environments, always seal HA with a moisturiser so it stays effective.
