Activator Serum Stem Cells is the ultimate creation of Nescens biological anti-aging research, and increases the regenerative power of stem cells in the epidermis. This targeted activation gives life to new cells, optimising epidermal regeneration and bringing a youthful look to the skin. The serum is particularly effective on mature skin which may Be lacking in density and firmness.

Biological principle
With age, the replication capacity of cells decreases and the number of duplications is reduced. This is due, in part, to the fact that each cell division shortens the telomeres (non-coding region of the DNA at the end of the chromosomes).

Cells enter a biological ageing process when their telomeres reach a critical length. Only telomerase can synthesise new growth, thus avoiding the reduction of telomeres with each division cycle. However, this enzyme complex is only present in stem cells and its activity decreases with age. Stem cells therefore gradually lose their ability to regenerate tissues. Additionally, to the loss of their ability to replicate, senescent cells present alterations that negatively affect the dermal tissue, leading to skin ageing; these alterations include changes in the synthesis of the extracellular matrix, as well as an increase in protein destruction and inflammation.
