Frequently Asked Questions
Explore the most common questions about this system, compatibility, accessories, and treatment use cases.
01
What is violet (405nm) light used for therapeutically?
Violet 405nm light has demonstrated antimicrobial properties through photodynamic inactivation of bacteria and viruses. Research shows effectiveness against a range of pathogens including MRSA. It is used clinically for wound infection management, oral health conditions, acne treatment, and general antimicrobial applications.
02
Why combine green and violet rather than red and violet?
Green 520nm light has higher absorption in hemoglobin-rich tissue compared to red wavelengths, making it more efficient at delivering energy to superficial vascular structures. Combined with violet antimicrobial action, the GrVi creates a powerful combination for treating infected or inflamed surface tissue where both antimicrobial and healing effects are needed.
03
Can the GrVi treat acne effectively?
Yes. The 405nm violet wavelength targets the porphyrins produced by P. acnes bacteria, generating reactive oxygen species that destroy the bacteria. The 520nm green light complements this by addressing inflammation and promoting tissue healing. This dual approach targets both the bacterial cause and inflammatory symptoms of acne.
04
Is this laser effective for oral health applications?
Yes. The antimicrobial properties of 405nm violet light make the GrVi well-suited for oral health applications including periodontal conditions, post-extraction healing, and management of oral infections. The compact form factor allows easy access to oral treatment areas.
