The special 585nm treatment light of the NLite laser heats and controls the fine capillary system in the dermis. Due to the extremely short energy release within only 150 microseconds, in contrast to conventional dye lasers, the finest vessels are not destroyed, but heated to their load limit within their thermal relaxation time. The absorption of yellow light in these tiny blood vessels leads to a thermal effect and inflammation in the endothelial cells of the vessel walls.
This stimulates the natural wound healing response of the tissue to a high degree without causing residual cell necrosis.
As a result of this inflammatory reaction, cytokines are released and growth factors are stimulated. This leads to the formation of collagen and in particular the high release of TGFß leads to an enormous activation of the immune system.
The enormous increase in TGFß by 1,500% (see study by Prof. Dr. Chu), causes unique treatment results for all forms of inflammatory acne.
Mechanism of action NLite V when the laser energy is released into the fine capillaries:
- The absorption in oxyhemoglobin leads to a warming of the capillary walls.
- Inflammation mediators are released; these stimulate the fibroblast cells in the extracellular skin matrix.
- These fibroblasts produce new collagen
