Optimal Wavelength: Medical devices typically use a range of wavelengths tailored for different skin issues.
While a DIY red light therapy mask can be a fun and cost-effective project, its effectiveness may not be on par with commercial products designed for therapeutic use. If you are serious about red light therapy, consider investing in a professionally made device to ensure safety and efficacy. If you decide to proceed with the DIY approach, take care to follow safety protocols and monitor your skin’s reaction closely.

Creating a DIY red light therapy mask using a plastic mask and red LED diodes is possible, but there are several factors to consider for effectiveness and safety:
Effectiveness: DIY masks can provide some benefits if the LEDs are of good quality and emit light at the right wavelengths (600-650 nm). However, the intensity and uniformity of light exposure may not match that of professionally designed devices.

- Optional: a resistor to prevent overheating.
- A plastic face mask (ensure it’s comfortable and fits well).
- Placement of LEDs: Space the red LEDs evenly across the inside of the mask to ensure uniform light exposure. Leave some space around the eyes and mouth for comfort.

DIY Red Light Therapy Mask Steps
- Use the mask for about 10-20 minutes per session, a few times a week, depending on personal comfort and skin sensitivity.
Usage:
- Power Connection: Attach the power source securely, ensuring it can be easily disconnected when not in use.
