NB-UVB Narrowband UVB
Narrowband UVB phototherapy delivers controlled ultraviolet light to support immune regulation, melanocyte activation, and gradual restoration of skin pigmentation.
Mechanism of Action
Photobiomodulation & Cellular Activation
NB-UVB light interacts with molecules in the skin, triggering photobiological and photochemical responses that influence cellular and molecular activity.
Immune Modulation
Targeted UVB exposure may help reduce pathogenic T-cell activity and inflammatory signaling, protecting melanocytes from immune-mediated damage.
Immune System Regulation
UVB-induced cytokine modulation contributes to the regulation of local and systemic immune responses.
Melanocyte Activation
NB-UVB stimulates melanocyte activity and tyrosinase function, supporting melanin synthesis and repigmentation.
Melanin Transfer & Skin Repigmentation
It may enhance the ability of keratinocytes to receive and distribute melanin, helping gradually restore more even skin coloration.
Clinical Consideration
NB-UVB treatment schedules and dosing are individualized according to skin type, lesion characteristics, and clinical response. Therapy may be combined with other modalities as part of a comprehensive plan determined by a qualified physician.
