Designed by Sofia Rays and born from a personal journey of healing and heart, RAYS helps you transform not just how you look — but how you feel, think, and live. After experiencing heart surgery and learning to live with arrhythmias, Sofia discovered something extraordinary: the power of alignment. Alignment between body, mind and purpose.
