fibroblastos / fibroblasts
Skin firmness depends on much more than collagen. Fibroblasts, elastin and the extracellular matrix form part of an architecture that changes with age. Understanding it helps us approach skin ageing more intelligently.
Skin is constantly renewing and repairing itself, but these processes change over time. Understanding skin regeneration means looking at cells, fibroblasts, the extracellular matrix and how their behaviour evolves with age.
A senescent cell is not dead: it has stopped dividing but remains active and can influence its surroundings. We explain cellular senescence and why it is increasingly studied to understand skin ageing.
