How to Adjust the Straps for the Neck & Chest Pro Light Therapy MaskUpdated 3 hours ago

Position the Mask
Place the mask flat with LED lights facing up. Hold it against your neck with the LED side touching your skin, covering your décolletage area comfortably.  The mask comes with two adjustable straps.

Secure and Adjust
Wrap both straps around the back of your neck and press the velcro ends together firmly to secure. The straps should feel snug but not tight. Adjust the strap length using the velcro connections for a comfortable fit.

Check Fit (Swap Strap if Needed)
Ensure the mask feels secure and comfortable with straps lying flat and untwisted. If the S/M strap feels too tight, swap with your included L/XL strap: unthread the S/M strap from the right-side slider, and thread the L/XL strap through the slider (velcro ends pointing away), adjust length, and fasten behind your neck.
