The Problem: Numerous medical studies have shown that continuous pressure on your face and skin will result in the formation of wrinkles, acne, and contributes to overall skin aging. Why it Works: Simple, instead of your face smashed against your pillow at night, your head is comfortably supported by the YourFacePillow, allowing your face and skin to be free from any harmful contact and breathe naturally. Thus, the YourFacePillow works as an ANTI AGING, ANTI WRINKLE, and ACNE TREATMENT SKIN CARE SOLUTION. The YourFacePillow can be used for either back or side sleepers. Yes you can sleep on your side using the YourFacePillow. While the primary reason for many using the pillow will be to aid in comfortable back sleeping to ensure complete facial protection, the YourFacePillow is the only pillow to facilitate side sleeping and still isolate your face from pressure due to the patented design. If your intention is to use the YourFacePIllow to sleep on your back, but think you will have difficulty adjusting, we recommend you start on your side and rotate to your back over a few weeks. We suggest you sleep close to the side that feels most comfortable to you and not directly in the middle of the pillow, so you can gently rest your head on the preferred side support. Like any new sleeping position, it can take days to weeks to adjust, so please be patient. REST ASSURED - We use CertiPUR Certified foam. Our pillows are made without PBDEs, TDCPP, TCEP flame retardants, mercury, lead and heavy metals, formaldehyde, phthalates. WHAT IS IN YOUR PILLOW? The YourFacePillow includes a Hypo-Allergenic Inner Cover as well as a removable and washable Bamboo outer cover. A satin case is available separately. Please ensure factory case is used for proper functionality. PLEASE DON?T HESITATE TO CONTACT US IF YOU HAVE ANY QUESTIONS.
