Instructions for use

As part of the Nescens cosmeceutical plan, the activator serum, stem cells, is designed for use twice daily, before application of Nescens correcting care range, to boost the regenerative potential of the epidermal cells.

  1. Nescens priming care
    Wash the face and neck with cleansing gel. Dry thoroughly. Spray metabolic activator tonic onto hands and apply to perfectly cleaned and dried face and neck. Massage lightly into skin to optimise the penetration of the tonic.
  2. Nescens serum

Swiss anti-aging science

The activator serum, the ultimate creation of Nescens Biological anti-aging research, 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.

Basic biological principle (rationale)
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.
