Each face is unique, which can affect how the mask adheres. Proper positioning of the eye openings is essential. Depending on the length and width of an individual's face shape, the placement of the mouth opening may vary; however, this does not impact the usage or effectiveness of the LED therapy.
For users with shorter faces, we recommend maintaining the eye position. Then tighten the velcro fasteners so that the mask sits looser at the bottom of the face and illuminates from a greater distance, which also covers the chin.
