Clinical perspective: Red light therapy produces results proportional to consistency and correct protocol — not just owning the device. As a certified athletic therapist who uses and recommends red light tools daily, the biggest missed opportunity I see is inconsistent sessions and incorrect wavelength selection for the goal. This guide closes that gap.
Learning how to use the Bon Charge red light mask correctly takes about five minutes — and it makes the difference between mediocre and meaningful results. The mask uses 240 LEDs across 630nm red and 850nm NIR wavelengths, with three intensity levels and selectable modes. I own the Bon Charge Mini panel and have evaluated the face mask clinically; the setup is straightforward once you understand what each control does.

First use: unboxing and initial charge
Before your first session, charge the mask fully. Connect the USB cable to the controller unit's charging port and plug into any USB power source. A complete charge from empty takes 1.5-2 hours and delivers approximately 3 hours of use. The LED indicator on the controller will turn green when charging is complete.
The mask ships with the flexible silicone shell, the detachable controller, the headstrap, and a USB charging cable. The silicone is A-grade and contours directly to facial anatomy — including contoured eye cups, so no separate goggles are required during sessions.
Understanding the controller: timer, wavelengths, and intensity
The Bon Charge face mask controller has three main functions. Knowing exactly what each button does eliminates guesswork.
| Control | Function | Options |
|---|---|---|
| Power button | On/off, wavelength mode cycle | Red only → NIR only → Red + NIR combined |
| 'E' button | Intensity level | Level 1 (low) → Level 2 (mid) → Level 3 (high) |
| Timer button | Auto-shutoff timer | 10 min → 15 min → 20 min |
Press the power button once to turn on in red-only mode. Press again to switch to NIR-only. Press a third time to activate combined red + NIR. Use the 'E' button to cycle through intensity levels — start at level 1 for your first session and work up to level 3 once your skin has adapted over a few sessions.
Red vs NIR vs combined — which setting to use
Wavelength selection should match your treatment goal. These aren't interchangeable settings — they have different tissue penetration depths and biological targets.
| Mode | Wavelength | Penetration | Best for |
|---|---|---|---|
| Red only | 630nm | Superficial (1-2mm) | Collagen, skin texture, fine lines, surface healing |
| NIR only | 850nm | Deeper (5-10mm) | Jaw tension, TMJ, deeper tissue recovery, inflammation |
| Combined | 630nm + 850nm | Both layers | General anti-aging protocol, maintenance sessions |
"Most people default to combined mode and that's fine for general maintenance. But if someone comes to me with jaw tension or post-procedure inflammation, I direct them toward NIR-only at full intensity — the 850nm wavelength reaches tissue that 630nm simply won't penetrate at this irradiance. Skin goals? Lead with red. Recovery goals? Lead with NIR."
Step-by-step: how to run a session
- Cleanse your face. Remove all makeup, SPF, and serums. Photobiomodulation requires unobstructed skin contact — products block and scatter light before it reaches the dermis.
- Adjust the headstrap. The silicone mask is flexible, but the strap tension determines how well the LEDs contact your skin. Snug without uncomfortable pressure — the LEDs should sit flush across the forehead, cheeks, and chin.
- Power on and select mode. Press the power button to cycle to your target mode (red, NIR, or combined). Press the 'E' button to set intensity. Set your timer (10, 15, or 20 minutes).
- Relax in position. Lie down or sit with your head supported. The mask is cordless — you're not tethered to anything. Minimal movement keeps the LEDs in consistent contact.
- Post-session. The mask shuts off automatically at the timer endpoint. Apply your serums and moisturizers immediately after — red light transiently increases skin permeability, which may improve topical absorption.
Bon Charge mask how to charge — the quick answer
Charging the Bon Charge mask is straightforward. Plug the included USB-A cable into the port on the controller unit. Connect to any USB wall adapter or power bank. The charging indicator light shows red while charging and turns off (or changes color depending on firmware version) when full. A full charge lasts approximately 3 hours of active use, which works out to 9-18 sessions before needing to recharge.
If storing the mask for more than a week without use, store at 40-60% charge. Storing lithium batteries at full charge for extended periods degrades capacity faster.
Clinical protocol: how often and how long
Bon Charge recommends 3-7 sessions per week at 10-30 minutes. Clinically, I'd narrow that down: 5 sessions per week at 15 minutes, using the combined mode at intensity level 2-3. This matches the dosing used in controlled trials — Wunsch & Matuschka (2014) documented statistically significant improvements in skin complexion and collagen density in 113 participants using this general dose range.
Daily use is safe. At 630nm and 850nm, these wavelengths do not cause UV-type photodamage. The ceiling risk is mild, transient warmth from extended NIR sessions — not a clinical concern at the timer-capped session lengths. For questions about optimal frequency for your specific goals, see how often you should use red light therapy.
Cleaning and storage
Clean the mask after every 2-3 sessions or after any sweaty use. Use a slightly damp cloth — water only, no alcohol wipes, no solvent-based cleaners. The silicone is durable but solvents will degrade the material and can compromise the LED array underneath.
Store in the included pouch away from direct sunlight. The LED emitters don't degrade from use — they degrade from heat exposure and UV over time. A drawer or the original box works fine.
Common mistakes to avoid
- ✗ Using on product-covered skin. Serums and SPF scatter and absorb photons before they reach the dermis. Clean skin only.
- ✗ Inconsistent frequency. Three sessions then nothing for two weeks produces no measurable benefit. Consistency is the mechanism — mitochondrial upregulation requires repeated stimulus.
- ✗ Always using maximum intensity. Level 3 isn't automatically better. If your skin is reactive or you've just had a procedure, level 1-2 allows recovery without overstimulation.
- ✗ Loose strap fit. Air gaps between the LEDs and skin reduce effective irradiance at the tissue level. Snug fit matters.

Frequently asked questions
How long should I use my Bon Charge mask?
Use the Bon Charge mask for 10-20 minutes per session. Most research on red light therapy for skin uses 10-15 minute sessions. Start at 10 minutes and increase if your skin tolerates it well.
Can I use Bon Charge mask every day?
Yes. Bon Charge recommends 3-7 sessions per week. Daily use is safe for most people — red light at these wavelengths and irradiance levels does not cause photodamage. Consistency drives results.
How do I charge my Bon Charge mask?
Plug the included USB cable into the charging port on the controller unit. A full charge provides approximately 3 hours of use. Charge before first use and store partially charged when not in use for extended periods.
What setting should I use on my Bon Charge mask?
For anti-aging and collagen stimulation, use red light (630nm) or combined red + NIR. For deeper tissue recovery or muscle tension around the jaw and neck, use NIR (850nm) alone. Start at intensity level 1-2 and work up to level 3 as tolerated.
Final verdict
The Bon Charge face mask has a clean, functional interface — three wavelength modes, three intensity levels, and a built-in timer. Once you understand what the power button, 'E' button, and timer do, setup takes under 30 seconds. The protocol that produces results is consistent: clean skin, combined mode, intensity level 2-3, 15 minutes, 5× per week. To see what that translates to on skin over time, check out Bon Charge before and after results, and for the full technical evaluation of the device, read our in-depth Bon Charge review.
