OBAGI MEDICAL ELASTIDERM FACIAL SERUM Size: 1 oz Condition: Brand New (No box) *Some minor wear (scratches on bottle) OBAGI MEDICAL ELASTIDERM FACIAL SERUM Elastin is a protein in the skin and a component of the dermis that is critical for healthy, youthful-looking skin. As we age, we lose and damage elastin, an essential protein responsible for skin’s elasticity and ability to keep its bounce. The natural depletion of elastin is accelerated by sun exposure, resulting in the appearance of sagging and crepiness as well as the loss of firmness in the skin. Powered by patented and proprietary Bi-Mineral Contour Complex™, ELASTIderm Facial Serum is specifically designed to promote the three necessary stages of developing healthy, functional elastin.
