How to use an LED face mask

Every device comes with manufacturer instructions covering session length, frequency and safety. Those instructions take precedence over anything written here — including anything written by us. What follows is the general shape of a routine, not a protocol.

Before

Start with clean, dry skin. Most manufacturers advise against applying active serums, oils or heavy creams underneath a device, partly because products can sit between the light and the skin, and partly because some ingredients are better applied afterwards.

Remove make-up and SPF properly. A quick wipe is not the same as a cleanse.

During

Position the device as the instructions describe and keep it still. Follow the eye-protection guidance supplied — some devices are designed to be used with eyes closed, others include shields, and the two are not interchangeable.

Do not extend a session beyond the stated length on the assumption that longer is better. Manufacturer timings exist for a reason.

After

Continue with your usual skincare — serum, moisturiser, and SPF if it is daytime. Nothing about LED use removes the need for sun protection.

Building the habit

• Anchor it to something you already do, such as after cleansing on set evenings.
• Keep the device visible and charged rather than in a drawer.
• Choose a realistic frequency you can sustain, within the manufacturer's guidance.
• Clean the device as instructed — it touches your face.
