Skin structure and ageing factors
Skin structure
In the process of skin ageing, fibroblasts are playing a key role.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
We can find different effects in the skin depending on the type of aging factors
CHRONOAGEING (INTRINSIC AGING)
• Volume loss • Texture alteration • Dryer skin
PHOTOAGEING (DUE TO SUNLIGHT)
• Elastic tissue degeneration – sagging • Pigmentation disorders – lighter skin & blemishes
MECHANICAL (EXPRESSION LINES)
• Forehead transversal wrinkles • Glabella lines • Crow’s feet • Upper lips lines
