The Moisture Lock Technique

Why moisture matters

Skin defends itself against sun, pollution and air-conditioning, and it steadily loses water through its surface. Cool, dry rooms, and air conditioners in particular, can add to that dryness.

The three-layer idea

A moisture lock works in layers. A humectant such as hyaluronic acid draws water into skin. A moisturiser softens and smooths. Then a film-forming step, which for many people is a sheet mask, helps slow moisture loss so skin feels soft and hydrated.

A simple order

1. Cleanse gently; double cleanse if you wore sunscreen or makeup.
2. Apply a hydrating serum to slightly damp skin.
3. Moisturise: a gel for humid weather, a cream for dry or cold weather.
4. Finish with your sheet mask for 2–3 hours, following the pack directions.

Small habits that help

• Use lukewarm, not hot, water on your face.
• Change pillowcases regularly.
• Avoid letting the bedroom get too dry with AC or heaters.

Be patient: skin usually needs several weeks of steady use before you can judge a routine fairly.
