Clinical Origins

The science of Eighth Day began with Dr. Nakhla’s work in wound healing, using bioidentical dressings to restore skin after surgery. He realized that aging skin, damaged by sun, environment and stress, could benefit from the same approach. This insight became the foundation for Eighth Day: skincare that supports the skin’s natural repair and renewal.
