Why Perfection Collection? After suffering for years from migraines and sinus infections that caused debilitating pain, the creators of Perfection Collection sought relief. Through extensive testing of various fillers for pillow masks, they decided on flaxseed due to its amazing properties and attributes: Flaxseed's high oil content retains temperature changes better than other fillers. When warmed, the seeds produce a therapeutic moist heat. When cooled in the freezer or fridge, the flaxseeds remain flexible but still nice and cold! The smooth, tiny seed allows for a more comfortable fit and feel to a sensitive face. Once they found the right filler, they pulled from their extensive master esthetician background (both in the clinic and spa) to find the perfect design to target facial pressure points. Targeting these pressure points allows for the most immediate migraine and sinus pain relief.
