Skin structure and ageing factors
Skin structure
Fibroblasts play a key role in the skin ageing process.They synthesise the supportive structure in the skin, producing two main proteins: collagen and elastin.
Young, healthy skin
Aged skin: as the skin ages, collagen and elastin degenerate and fibroblast activity is reduced.
Mature skin: after significant degeneration.
Fibroblast - fibroblasts produce collagen, which is the major structural protein in the skin.
Elastin - fibres that are loosely arranged in all directions in the dermis and provide elasticity to the skin.
Collagen - fibres that make up a majority of the intra-cellular matrix of the dermis and impact the skin’s toughness and strength.
Skin ageing factors
Different factors affect skin ageing
CHRONOAGEING (INTRINSIC AGEING) • Volume loss • Texture alteration • Dryer skin
PHOTOAGEING (DUE TO SUNLIGHT) • Elastic tissue degeneration – sagging • Pigmentation disorders – lighter skin & blemishes
MECHANICAL AGEING (EXPRESSION LINES) • Forehead transversal wrinkles • Glabella lines • Crow’s feet • Upper lip lines
