68x15x1.0mm 615nm Longpass Filter for IPL Pigmentation

615nm Longpass Filter for IPL Pigmentation   The 615nm long pass optical beauty filter for IPL (LP615) is a clinically validated optical filter specifically designed for deep-targeted intense pulsed light (IPL) therapy in the treatment of pigmentation. Featuring a cut-off wavelength of 615nm, this filter effectively blocks all wavelengths below that threshold while allowing transmission of yellow-red to near-infrared (NIR) light. This spectral selection enhances tissue penetration depth, enabling targeted delivery to the reticular dermis, where it induces controlled thermal effects and extracellular matrix remodeling—critical mechanisms for addressing persistent pigmentation and vascular irregularities.   Clinically, the LP615 filter is extensively utilized in the management of post-inflammatory hyperpigmentation (PIH), improvement of skin texture, reduction of diffuse redness, and minimization of prominent facial veins. In the treatment of melasma, its application should be carefully…
