How to fit your skincare routine around your light therapy sessions.

General guidance is to apply light therapy to clean skin and to be cautious combining it with strong actives, for example retinoids or exfoliating acids.If you use prescription skincare or have sensitive skin, check with your dermatologist.For routine use: apply your moisturizer or serum after your session rather than before, products applied beforehand can interfere with how well the light is absorbed.

Can I use skincare products before or after treatment?

Why no eye protection is needed with the Laser Pro Mask.

No eye protection is needed while using the mask, and there is no risk of eye damage. The mask is FDA-cleared as a Class II device for home use without protection. It is low-power and non-thermal, and includes an open section directly over the eyes, so nothing sits on the eye itself, you can keep your eyes open or closed comfortably throughout your session.The lasers surrounding that open section are positioned to still treat the under-eye area, so even though the eyes themselves are left open, the surrounding skin is included in your treatment.
