the future is here: advanced at-home laser skincare
6-8x The Efficacy of LED Masks
Delivers 143mW/cm² of power compared to <20mW/cm² from standard LEDs, for faster, deeper, and more effective skin transformation.
FPT Ultra-Narrow Light Technology
Proprietary innovation focuses each laser beam to <20°, ensuring energy is delivered precisely to each facial zone with minimal waste.
Eye-Safe, Pressure-Free Comfort
Designed to avoid eye areas while still treating nearby skin. No goggles required. The gentle, floating fit avoids skin creasing, and all light output has passed rigorous safety testing for daily, confident use.
140 VCSEL Laser Chips with Zoned Light Control
Each beam is independently directed, delivering even, controlled treatment across the entire face, mimicking clinical med spa results.
6x More Powerful than LED
Compared to traditional LED, FPT light boosts energy efficiency by 6 times.
Deep Collagen Activation
4 different wavelengths, featuring the long-wave 1064nm infrared light, penetrate the skin to boost collagen.
Precision Targeting
140-beam light array accurately treats fine lines by facial zones.
Optimized Light Delivery
Flexible curved design hugs the skin to reduce light loss and maximize results.

frequently asked questions
What is FPT ultra-narrow optical chip technology?
What is FPT ultra-narrow optical chip technology?
Through joint research and development with optical solution experts, we created a patented chip that enables FPT (Focus Photothermal Therapy) using Focused Ultra-Narrow Light. By controlling and reducing the dispersion angle, altering the characteristics of the light radiation area, enhancing the concentration of light waves, increasing unit energy, and minimizing energy loss, we have significantly improved energy efficiency and enhanced the reduction of fine lines.
Do different waves of light penetrate each area of the face in eaach mode?
Do different waves of light penetrate each area of the face in eaach mode?
Yes, there is distributed light distribution for different areas in each mode, with four light waves irradiating different areas at the same time to target skin problems.
How many light sources are there in total and what are their wavelengths and functions?
How many light sources are there in total and what are their wavelengths and functions?
1: Red light 660nm - can enhance the skin's metabolism and improve dullness.
2: Near-infrared light 850nm - can enhance cell activity and make the skin elastic.
3: NIR light 940nm - activates the microcirculation of the skin, inhibits melanin, and improves skin rejuvenation.
4: Long-wave infrared light 1064nm - Promotes collagen regeneration in deep tissues and slows down skin aging rate.
Will it fall off easily and can I walk with it on?
Will it fall off easily and can I walk with it on?
It is lightweight, snug and soft. It can be worn while walking or even doing yoga.
How many modes are there? What are their roles?
How many modes are there? What are their roles?
3 Modes - Soothing Mode, Standard Mode and Deep Mode
3 Timings - 10 minute, 15 minute and 20 minute timer settings
Can I still use it if I have acne or wounds on my face?
Can I still use it if I have acne or wounds on my face?
Facial acne is often caused by internal inflammation. Using a mask during a breakout can worsen its appearance. Areas with open wounds need space and airflow to prevent infection. Wearing a mask product in this condition is not recommended.
Is the light harsh without the eyeglass design?
Is the light harsh without the eyeglass design?
No, the light is not harsh without the eyeglass design. The 4D Laser Light Therapy Mask has been designed to effectively reduce the impact of dispersed light on the eyes. It has been tested for eye safety and is comfortable to use without additional shielding.
