I recently purchased the Dermaflash Luxe and wanted to make sure I had enough blades for last awhile, I found this refill kit with an auto delivery option that’s perfect for my needs. Subscription date can easily be changed and arrive on your schedule. Blades are what make this system efficient. They are sharp, but safe to use and leave you face smooth. Easy to insert and remove from the Luxe. Kit includes 4 blades and the face wash, which in transparency, I do not use. I wish I could just get the blades, but the device instructions recommend using their wash, so I doubt selling the blades on their own on a replenishment system won’t happen.
