Blue Light 415nm

Blue light at 415 nanometers is the reference wavelength for antibacterial action in dermatological phototherapy. Unlike red and infrared light, which target mitochondria, blue light acts through a distinct photochemical mechanism.
Cutibacterium acnes bacteria (formerly Propionibacterium acnes), the main cause of inflammatory acne, naturally produce porphyrins—photosensitive molecules. When blue light at 415 nm reaches these porphyrins, it triggers a photodynamic reaction that generates reactive oxygen species (ROS). These ROS destroy bacterial walls, eliminating bacteria without antibiotics.
Proven benefits
- Destruction of acne-causing bacteria — targeted action without antibiotics
- Sebum regulation — helps reduce excess sebum production
- Skin purification — reduces blemishes and inflammation
- Prevention of breakouts — regular use maintains clear skin
Integration at NOOĀNCE
Blue light at 415 nm is integrated into the Flexidome Pro and Multi-Function LED Mask, enabling a dedicated "clear skin" mode. Combined with red and infrared wavelengths, it offers a comprehensive approach: blue light purifies the surface while red and infrared regenerate deeply.
