Eye Brightener Hydrocolloid Refill Patches play a dual role when using your under-eye LED treatment . Not only they securely attach the device to your skin, allowing for a hands-free treatment, but they also offer additional skincare benefits.  Each patch is enriched with the powerful combination of niacinamide and amino acid-rich peptides, working in harmony to illuminate dark circles and create a smoother, more revitalised under-eye area.
