Oxygenating serums have recently burst onto the scene and are proving effective when it comes to brightening and hydrating skin. As each oxygen molecule penetrates the epidermis, it liberates two water molecules wherever they're needed. And as we all know, well-hydrated skin is our best preemptive strike against the appearance of wrinkles. The result? Plump, peachy, baby-soft skin! What's more oxygen-based treatments are hypoallergenic, meaning they're suited to all skin types, sensitive skin included.
