Phototherapy is a painless, relaxing, non-invasive skin-care treatment that has multiple benefits—particularly stimulating collagen and treating mild to moderate acne. Phototherapy treatments work by using an array of bright light-emitting diodes (originally developed by NASA!) that send low-level light energy into the deeper layers of the skin.
Photo Rejuvenation: a long enough wavelength to penetrate the epidermis (outermost layer of the skin) and reach the dermis (the middle layer of the skin). This enables it to reach fibroblasts, special types of cells that sit beneath the skin and manufacture collagen – a protein that helps tighten and firm the skin and heal wounds.
