PDT LED Masks Explained: What the Technology Actually Does for Skin

PDT, or photodynamic therapy, uses specific light wavelengths to trigger cellular responses in skin, from boosting collagen production to calming inflammation. The DermaBeam 7-Color LED Light Therapy Mask applies this across seven wavelengths, so different settings target lifting, whitening, or hydration.

The benefit of a multi-color mask over a single-wavelength device is flexibility: your skin's needs change week to week, and having seven options means you're not locked into treating just one concern.
