For fine lines, shortlist documented red or red/near-infrared modes; for acne pimples, consider an appropriate blue or red-and-blue device as part of an acne-care plan. For dark spots or persistent redness, address the cause with suitable skincare and professional advice before choosing an LED color. Green, yellow, purple, cyan, and white are not a universal treatment menu: choose a supported purpose, and leave out settings that do not serve your goal. [1, 4, 5, 6]

7-Color LED Light Therapy Chart: Choose by Skin Goal
Start with the concern you most want to address, then use this 7-color LED light therapy chart to narrow your options. Red and blue have established roles in light-based skincare, but a color label still needs to match the device’s intended purpose. [1, 4]
Red
For fine lines, shortlist red or red/NIR options. Next step: A documented anti-aging purpose and routine.
Blue
For acne pimples, consider a device intended for acne care. Next step: Visible-light devices do not address blackheads, whiteheads, cysts, or nodules. [4]
Green
For dark spots, prioritize the cause and sun protection. Next step: Do not replace a pigmentation-care plan with an assumed green-light benefit. [5]
Yellow / amber
For persistent redness or sensitivity, establish suitability first. Next step: A yellow or soothing label does not establish a rosacea treatment. [6]
Purple
For combined concerns, first identify your main priority. Next step: Use a documented combination only when its intended purpose fits; benefits do not automatically add together.
Cyan
For oiliness alone, do not add a cyan session by default. Next step: Choose skincare appropriate to the concern rather than an unsupported color assignment.
White
For general rejuvenation, begin with a defined anti-aging mode. Next step: White appearance does not establish greater depth or better results.
If your concern falls outside a mode’s supported purpose, leave that setting out. A seven-color chart helps you narrow a choice; it does not require you to build a seven-step routine.
Why Your Skin Goal Matters More Than the Color Count
For fine lines, there is a concrete reason to investigate red and red/NIR. In a randomized, placebo-controlled, double-blinded study, Lee and colleagues tested 633nm red light, 830nm near-infrared, and their combination, reporting improvements in measured wrinkles and elasticity under the tested protocols. [1]
The buying lesson is to connect your goal with a studied light approach and a suitable device routine. This study did not compare seven-color masks, establish choices for acne or pigmentation, or test GLOW 4D; its results cannot be transferred to those questions.
INIA’s Approach: Start with the Goal, Then Design the Mode
A color chart leaves you with a practical question: how do you turn those choices into a routine? INIA’s approach with GLOW 4D is to organize light combinations into named modes, with anti-aging as the foundation and additional options for other priorities.
This lets you evaluate the setting relevant to you before deciding whether the extra modes are useful. Coverage, fit, and ease of use then help you judge whether the complete device suits your day-to-day routine.
Which GLOW 4D Mode Should You Consider?
INIA GLOW 4D pairs visible light with 850nm and 940nm dual NIR in four defined modes. Here is how to assess those options against the goal that brought you to the color chart. [2]
Fine lines as your main priority: start with Anti-Aging Mode. Red plus dual NIR forms the mask’s anti-aging foundation, giving you a specific combination to evaluate before deciding whether you need additional modes. [2]
Acne pimples as your priority: consider Anti-Acne Mode within your acne-care plan. Its blue-plus-dual-NIR combination is the relevant option to discuss with your dermatologist; visible-light acne devices are not an answer to blackheads, whiteheads, cysts, or nodules. [2, 4]
Cosmetic dullness as your priority: look at Glow Mode. This is the amber-plus-dual-NIR option, while persistent dark marks still call for cause-focused pigmentation care and sun protection. [2, 5]
Both fine lines and breakouts on your list: compare Full Rejuvenation Mode with your main priority. It combines red and blue with dual NIR, giving you a combined-light option rather than requiring you to invent a sequence of separate colors. [2]
Use these descriptions to understand the available combinations, not to rank clinical results. Adding lights does not automatically make a mode better, and you do not need all four modes to make the device useful to your routine.
The 4D wraparound design extends coverage around the lower face, jawline, and chin. Wireless operation offers flexibility during sessions, and magnetic under-eye cooling pads add a cooling option. [2]
Together, the modes, coverage, and wearable features give you a complete product setup to assess: the light choice, the areas covered, and the experience of using it. For redness or reactive skin, confirm suitability first; cooling is a comfort option, not a treatment for the underlying condition.
Start by identifying one main priority and its corresponding setting, then follow the included routine. If your goals change, reassess the relevant mode rather than extending sessions or adding their times together.
Follow the exact-model instructions for session length, frequency, and eye protection. AAD recommends discussing existing skin conditions and light-sensitive medicines with a dermatologist, and advises people with darker skin tones to seek guidance about pigmentation risk. [3]
Choose a Clear Routine for Your Main Goal
Choose red or red/NIR options for a fine-line priority, and an appropriate acne device for pimples. For persistent pigmentation or redness, establish the cause and care plan first rather than trying to solve the problem by cycling through colors.
Consider GLOW 4D if its anti-aging foundation, additional defined modes, lower-face coverage, wireless use, and cooling option fit your priorities. The right choice is a suitable routine—not a requirement to use seven colors.
Frequently Asked Questions
Should I use all seven LED colors in one session?
No. Choose the setting intended for your main goal and follow your device’s instructions. Do not add mode times together unless the instructions specifically allow it.
Which LED color should I choose if I have both fine lines and pimples?
