Not all peptides do the same thing. Some act as signals, others as carriers, while others target very different mechanisms. We explain how they work and why the specific peptides in a formula matter.
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.
