Regeneration booster

Thymulen®4 is a biomimetic peptide that mimics thymopoietin which is considered a youth hormone. This highly purified ingredient compensates for the natural loss of thymic factors related to the decline of the thymus with age. It increases the immune vigilance of the skin and helps regenerates the epidermal profile. By reinforcing the cutaneous immune defenses and boosting the epidermis regeneration, Thymulen®4 is “the” approach to fighting against aging.

Mechanism of action and stimulation of the skin's immune system:

  • Stimulates the growth and differentiation of keratinocytes
  • Stimulates the activation of Langerhans cells by activating GM-CSF (Skin Immune System Stimulating Factor)
  • Decreases the inflammatory response
  • Modulates the secretion of cytokines.


Thymulen®4 benefits include:
  • Improves skin regeneration
  • Stimulates the renewal of keratinocytes
  • Increases the synthesis of keratin and keratohyalin
  • Improves the function of the skin barrier, while reducing the trans-epidermal water loss
  • Densifies the skin
  • Prevents and combats expression lines and wrinkles.
