Important safety information
Keep the integrated eye shielding in place and your eyes closed throughout each session. Do not use within 48 hours of applying AHA products at active concentrations, while using prescribed retinoids or other medication known to cause photosensitivity (except under the direction of a qualified healthcare professional), or over citrus-derived essential oils or heavy occlusive balms. Not intended for persons under 18, those who are pregnant or breastfeeding, those with diagnosed photosensitive conditions such as porphyria or lupus, active skin cancer or undiagnosed skin lesions in the treatment area, or anyone advised by a clinician to avoid bright light exposure — consult a qualified healthcare professional first if any of these apply or you are unsure. If you experience persistent redness, swelling, irritation or any unexpected change in the skin, discontinue use and seek advice from a qualified healthcare professional.

10–20 min sessions
A short, restorative ritual — designed to slot into your weekly routine 3–4 times a week.
Adaptive — personalised by CELA
CELA selects which light modes anchor your protocol based on your skin scan, then updates as your skin responds.
Using It With Your Protocol
- 01 Cleanse. Start with a clean face — any CellSync cleanser will remove make-up, SPF and impurities. Clean skin maximises photon absorption.
- 02 Apply Serum. Apply your CELA-recommended serum — the mask helps your skincare feel more effective when paired with it.
- 03 Session. Place the mask and select your CELA-recommended wavelength mode. 10–20 minutes per session.
- 04 Seal. Apply your barrier cream immediately after. Post-session is the magic absorption window.
