Frequently asked questions
The Nimbus FAQ: Advice from Lumefu’s Beauty Experts, and frequently asked questions.
Can I use the mask after professional skin treatments?
Please wait at least one week until your skin has fully recovered (no wounds or swelling). For invasive or surgical procedures, consult your physician before use.
Is it safe for pregnancy or breastfeeding?
Use is not recommended during these periods as a safety precaution, although there is no evidence of direct harm from LED light.
How long should I use the Nimbus?
Just 15 minutes a day, 3 to 5 times a week as part of your skincare routine.
Which skincare products should I pair with the device?
Use on cleansed, dry skin. Follow with hydrating or repairing products after the session. Note: Avoid using active ingredients (Acids, Retinol, or potent Vitamin C) during light therapy to prevent irritation.
Is sunscreen required after use?
Our device is UV-free and won't damage your skin. However, we recommend applying sunscreen if you plan to go outdoors during the day to protect your skin.
How do I clean the device?
Wipe with a soft, damp cloth or alcohol-free wipes after each use. Do not submerge in water or use corrosive cleaners.
How long does the Nimbus take to charge?
A full charge takes approximately 2 hours.
Does it hurt?
Not at all. The Nimbus is 100% pain-free, non-thermal, and designed for maximum comfort.
When will I see results?
With consistent use, most users notice visible skin improvements in just 4 weeks.
How long should I use the Nimbus?
Just 15 minutes a day, 3 to 5 times a week as part of your skincare routine.
Should I close my eyes or wear an eye shield?
The nimbus provides eye shield and is safe for use with eyes open. If you are light-sensitive, we recommend closing your eyes for added comfort.
Can I use moisturizer before my session?
For best results, use on clean, dry skin. Makeup and heavy skincare can block LED light penetration. Save your serums and moisturizers for post-treatment.
How many LEDs does the Nimbus have?
It features 252 professional-grade LEDs: 84 Red (630nm), 84 Near-Infrared (830nm), and 84 Blue (415nm).
Is the Nimbus mask "powerful"?
True efficacy comes from precision, not just power. While excessive power can irritate the skin, the Nimbus is calibrated at 30 mW/cm²—the clinical "sweet spot" for safe and effective long-term results.
How do I use the device?
1. Unplug: For safety, the device will not operate while connected to the power supply.
2. Prep: Ensure skin is clean, dry, and free of all skincare or makeup.
3. Power On: Secure the mask and long-press the power button. The Nimbus will automatically shut off after its 15-minute session.
