Newkey offers seven colors for acne and wrinkles, but color count alone does not define a useful routine. Its listing does not clearly connect every mode to a stated wavelength or treatment plan. INIA GLOW 4D makes that choice clearer with five stated wavelengths, four goal-based modes, and a defined time for every mode.

Is Color Count the Deciding Factor?
Newkey's main promise is easy to understand: seven colors in one mask for concerns such as acne and wrinkles. But LED research evaluates specific wavelengths and treatment protocols—not the number of colors on a controller.
For acne, a randomized home-use study evaluated a defined combination of 420nm blue and 660nm red light.1 For visible skin aging, a randomized split-face study evaluated 633nm red and 830nm near-infrared light.2
Neither study tested the Newkey mask. Their practical lesson is simpler: if the wavelength and routine behind a color are unclear, the color name cannot tell the shopper what to expect.
Seven Color Choices—or Four Goal-Based Modes?
The difference is not simply how many light options appear on the controller. It is whether the mask turns those options into a routine the user can understand.
Newkey
Seven visible color selections
- Marketed for concerns including acne and wrinkles
- The wavelength behind every color is not clearly stated
- No clear goal-based session for each color
Best for: shoppers who mainly want multiple visible color choices.
INIA GLOW 4D
Four defined skincare routines
- Dedicated Anti-Aging Mode with 630nm red and 850/940nm dual NIR
- Additional Acne, Brightening, and Soothing modes
- A stated wavelength combination and session time for every mode
- Wireless 4D lower-face, jawline, and under-chin coverage
Best for: users who want one clear routine for several changing skin goals.
Why GLOW 4D Is the More Complete System
INIA GLOW 4D Wireless LED Light Therapy Mask does not trade anti-aging for versatility. Its Anti-Aging Mode combines 630nm red with 850nm and 940nm dual near-infrared light. The same mask then adds three more goal-based routines:
- Anti-Aging: 630nm red with 850nm and 940nm dual NIR for 10–20 minutes.
- Acne: 460nm blue with dual NIR for 5 minutes.
- Brightening: 590nm orange with dual NIR for 10 minutes.
- Soothing: 630nm red, 460nm blue, and dual NIR for 5–10 minutes.
The mode name identifies the goal. The wavelength combination explains the light selection. The recommended time defines the session.
GLOW 4D also extends coverage around the lower face, jawline, and under the chin. Wireless operation, on-device controls, and magnetic under-eye cooling pads make the selected routine easier to complete consistently.
Choose a Routine, Not a Color Count
Newkey may appeal to shoppers looking for an inexpensive introduction to multi-color LED care. But seven colors do not automatically create seven useful treatments.
GLOW 4D gives users a dedicated anti-aging system plus three additional goal-based modes, with the wavelengths and session times stated clearly. For users who want one documented mask for acne, visible aging, dullness, and mixed concerns, it is the more complete choice.
Frequently Asked Questions
Does Newkey publish the wavelength of all seven colors?
The listing reviewed for this article does not clearly identify the wavelength used by every color mode.
Do more LED colors mean better results?
No. Color count alone does not establish effectiveness. Wavelength, session design, coverage, and consistent use are more useful buying criteria.
Does GLOW 4D include dedicated acne and anti-aging modes?
Yes. GLOW 4D has separate Acne and Anti-Aging modes, plus Brightening and Soothing modes.
