Bought a little over a month ago, used twice & sanitized. I just can’t get in the habit of using it & consistency is key for this mask to work. Paid $455, it is near new & in absolutely perfect working condition. This powerful FDA cleared light therapy device designed for the full face features a combination of 100 red light emitting diodes in red mode and 60 blue light emitting diodes in blue mode that work together to help boost collagen product, improve skin density, smooth wrinkles, diminish discoloration, and clear acne for a clear, younger-looking complexion. For all skin types. ***Open to reasonable offers, please no lowballing***
