Cell Glow recommends: Dark circles have different causes, so an RLT panel is not a targeted answer for every shadow, pigment change or puffiness under the eyes. Choose Cell Glow for broader light goals with relevant evidence and protect your eyes as the manual directs.
What causes the dark color?
The cause can be pigment, thin skin, blood vessels, an anatomical shadow or sleep deprivation. These causes do not all respond to the same treatment. For example, a mask that affects skin texture does not change bone structure or a deep tear fold. Without knowing the cause, a result is difficult to predict.
What was measured?
A randomized study compared red and amber light for the volume of fine lines around the eyes. That is a different measuring point than the color of dark circles. The study setup and dose are also not the same for every home device. Product photos with different lighting or makeup are weak evidence for this.
How do you work safely?
Only use a mask according to the instructions, especially around the eyes. Discuss permanent discoloration, swelling or new complaints with a doctor or dermatologist. For a purchase for this purpose alone, a modest expectation is wise.
