TLDR
Skin collagen decreased with age and was less in the females at all ages and variations in collagen density in disease limit the use of dermal thickness as a guide to changes in its collagen content.Abstract:
Forearm skin collagen, dermal thickness and collagen density were measured in a large number of normal subjects as a standard reference for future studies. Skin collagen decreased with age and was less in the females at all ages. There is a direct relationship between skin collagen and dermal thickness but variations in collagen density in disease limit the use of dermal thickness as a guide to changes in its collagen content.read more

Bioengineering Methods and Skin Aging
TL;DR: The effects of the UV radiations on sun-exposed sites are superimposed on the morphological, biochemical, and functional changes occurring with aging, making distinction between the two phenomena hard.

A Novel Hyaluronic Acid Matrix Ingredient with Regenerative, Anti-Aging and Antioxidant Capacity
Patricia Gálvez-Martín,Cristina Soto-Fernandez,Jessica Romero‐Rueda,Jesus Cabañas,A. Torrent,Gloria Castells,Daniel Martínez-Puig +6 more
TL;DR: In this paper , the authors extract, characterise and evaluate the potential of an HA matrix ingredient to support anti-aging, showing regenerative properties in both fibroblasts and keratinocytes.

Suction blister techniques for measurement of human skin collagen synthesis.
P. Autio,Aarne Oikarinen +1 more
TL;DR: A new method for estimating collagen synthesis in human skin in vivo has recently been developed and suction blisters are induced on intact, and treated or diseased skin and types I and III procollagen propeptides are measured radioimmunologically in suction blister fluid.

TL;DR: In this article, the authors studied 21 healthy men from 61 to 81 years old who had plasma IGF-I concentrations of less than 350 U per liter during a six-month base-line period and a sixmonth treatment period that followed.

The determination of hydroxyproline in tissue and protein samples containing small proportions of this imino acid.
TL;DR: Method has been applied to a study of hydroxyproline distribution in cell particulates, tissue fluids, and purified plant and animal proteins, and significant amounts of hydroXYproline were found in crystalline preparations of pepsin, elastase.

A modified radiographic method for measuring skin thickness.
TL;DR: A modified radiographic method for measuring skin thickness has been described and has given consistent results, and it is suggested that this method will be of value in studying conditions in which changes in skin thickness are to be expected.

Osteoporosis, skin collagen, and androgen.
TL;DR: Total skin collagen was found to be decreased in untreated patients with osteoporosis, particularly women, but increased after treatment with androgens in women, suggesting decreased body collagen may possibly be a primary defect in osteopsorosis.

Roentgenographic visualization and measurement of skin thickness and its diagnostic application in acromegaly.
TL;DR: Some relatively simple methods for visualization and accurate measurement of skin thickness and to give some preliminary results on their application are described.
