For the skin care practitioner, this information is designed as an introduction the concept of cellular communication, and specifically cell-to-cell communication. This important information will assist you to understand and explain how cosmetic ingredients and technologies have the capacity to impact the skin on a cellular level without the need to treat the skin aggressively or to perform treatments that penetrate the dermal epidermal junction to achieve skin rejuvenation. Our epidermis contains a network of cells that intricately engaged with each other through various levels of communication at all times. Any time we stimulate the Keratinocyte it releases a chemical cascade of biological messengers and this action is why EpiStimology works so effectively without needles, blood or the use of dangerous topical anesthetics. Our cells need to communicate with each other for homeostasis, growth regulation, development and to coordinate their function and this is why EpiStimology works so effectively for skin rejuvenation.
