TY - JOUR T1 - Connective tissue biochemistry of the aging dermis. Age-associated alterations in collagen and elastin. A1 - Uitto,J, PY - 1989/2/1/pubmed PY - 1989/2/1/medline PY - 1989/2/1/entrez SP - 127 EP - 47 JF - Clinics in geriatric medicine JO - Clin Geriatr Med VL - 5 IS - 1 N2 - Cutaneous aging represents a complex situation in which at least two independent factors--innate aging and solar exposure--contribute to the development of degenerative changes in the dermis. The biochemical and ultrastructural evidence reviewed in this article indicates that reduced collagen deposition, as a result of diminished collagen biosynthesis and reduced proliferative capacity of the fibroblasts, could explain the development of dermal atrophy and would relate to poor wound healing in the elderly. At the same time, perturbations in the supramolecular organization of the elastic fiber network lead to alterations in the mechanical properties of the skin, as manifested by loose and sagging skin with reduced resilience and elasticity.
