How many LED lights are in the mask?
Our beauty mask contains 65 modules with a total of 325 high-precision LED lights, offering wider coverage, more even illumination, and higher treatment efficiency.
Why are some LED lights not lit?
When the mask is in near-infrared mode, the infrared light is invisible to the human eye. The LEDs are working even if you cannot see them.
How many light types are there, and what do they do?
The railia Rai-FACE mask provides five professional-grade light types: Red / Blue / Green / Yellow / Near-infrared. It supports multiple care modes including: Daily Balance, Firming & Anti-Aging, Spot-Lightening & Brightening, Oil-Control & Acne Care, Soothing & Desensitizing, and AI Smart Mode.The AI Smart Mode, powered by our exclusive Rai-SKIN™ AI technology, continuously analyzes your skin and customizes zone-specific light therapy for truly personalized skincare.
Will it harm the eyes?
No. The mask features medical-grade soft silicone eye covers that effectively block excess light. As long as the mask is worn correctly, it will not harm your eyes.
Is it suitable for sensitive skin? Will it cause allergies?
Yes, sensitive skin can use LED therapy masks. We recommend performing a patch test on a thin-skin area (behind the ear or along the jawline) at the lowest energy and shortest duration, then observe for 24 hours. If no redness, tingling, or itching occurs, you may gradually expand to full-face use.
Can pregnant women, menstruating women, or breastfeeding women use it? What about people who had facial surgery?
We do not recommend using the product during these special conditions. Please consult your primary doctor before using any beauty or skincare device with uncertain factors.
Can minors use it? What if a minor has severe acne?
We recommend minors consult a dermatologist first and use skincare products or devices only under professional guidance.
Can I apply skincare products during treatment? Can I use acne/brightening/hydrating products? Can I use sheet masks during LED therapy?
We do not recommend using sheet masks during light therapy. You may pair simple, non-irritating serums, lotions, or creams. Sheet masks are best used after the LED session.
What skincare products can be paired with the mask?
Follow the principle: “Simple prep before treatment, enhanced repair after treatment.” Choose gentle, simple-ingredient products to avoid negative reactions with light or unnecessary skin burden. Avoid products containing alcohol, fragrance, preservatives, or high-concentration acids (salicylic acid, AHA, retinoids).
Does the mask generate heat? Will I feel burning or tingling?
Generally, there should be no strong burning or stinging sensation. LED therapy works through photochemical reactions, not heat. A mild warm feeling is normal due to: ① LEDs producing minimal heat during operation. ② Red/near-infrared light promoting local blood circulation, creating a gentle warmth for some users.If you feel obvious burning, stop using immediately.
Is the railia APP compatible with all mobile phones?
The railia APP supports most smartphones, but it does not support devices using HarmonyOS 5.0 or above.
Will skin become dry after using the mask?
Dryness may occur depending on the light type and your skin condition, but it is not guaranteed. We recommend applying our customized post-care mask after treatment, followed by a gentle moisturizer for better hydration.
How long until I can see results?
LED therapy results are cumulative — benefits begin from your first use, but visible improvements generally appear after 2–8 weeks of consistent use. Please be patient with your skin. Consistency, along with proper cleansing, moisturizing, and sun protection, will deliver stable and lasting improvement.
Will it cause skin darkening?
No, correct use will not cause darkening. Darkening (post-inflammatory hyperpigmentation) is usually caused by: ① Excessive energy or treatment duration. ② Poor sun protection afterward. ③ Skin that is naturally prone to pigmentation. As long as you moisturize and protect your skin from the sun after treatment, you do not need to worry about darkening. If you'd like, I can beautify, format into FAQ layout, or convert into a product manual style.
Is the mask wired or wireless? Can it be used while charging?
Our beauty mask is designed to be fully wireless, allowing you to move freely during use. We do not recommend using the device while it is charging.
How often do I need to charge it? How long does one charge last?
A full charge supports around 5 complete uses. It takes about 2 hours to fully recharge.

● Extremely low battery: red light stays on
