The neck and chest skin is different from the skin on your face. Neck skin histology, which is the microscopic structure of tissues in this skin, is different from the skin on your face. It is thinner, more susceptible to damage, and it lacks sebaceous glands. This means that it requires different active ingredients and different vehicle delivery systems. MDAiRE Neck Tyte-R complex addresses these issues by using peptides that demonstrate neuromodulator effects, integrating a heavier use of DNA repair enzymes, and remaining focused on barrier restoration and NMF's (natural moisturizing factors). The neuromodulator effects of the peptides in the MDAiRE­ Neck Tyte-R effect the innervation (stimulation) of the neck muscles and overlying skin to give a smooth instead of textured appearance to the delicate crepey skin of the neck and decollete. The thinner skin of the neck and decollete require a heavier use of DNA repair enzymes and peptide complexes to reverse the sun and environmental damage that has taken place. Hydration of your skin on your neck and decollete skin will make your skin appear smoother and supple.
