Different skin concerns respond to different wavelengths of light. Here's how they map — with the science behind each in our library. In-depth guides for each concern are being added.
Fine lines & wrinkles
630–637nm red + 830nm near-infrared
The most-studied bands for collagen renewal and softening fine lines over a course of weeks.
Loss of firmness & elasticity
830nm near-infrared
The deepest-reaching band, associated with elastin and collagen-fibre repair.
Dullness & uneven tone
~580nm amber + red
Linked to radiance and the visible signs of photo-ageing.
Redness
~580nm amber
Associated with calming the look of redness in the upper-to-mid dermis.
Blemishes & oil
~415–420nm blue
Targets blemish-causing bacteria at the skin surface and helps regulate oil.
Neck lines
Red + near-infrared (no blue)
Thinner, drier skin benefits from the warm, deeper-penetrating bands.
