Inside the Dahlia Bed: What 630nm Red Light Actually Does

Most red light beds use two wavelengths. Dahlia uses four — 630, 660, 850, and 940 nanometers — and each one interacts with the body a little differently. We're going through each one over the next few weeks, starting at the shortest: 630 nanometers.

630nm is visible red light, and it's the gentlest wavelength in the Dahlia bed's lineup. It works mostly at the skin's surface rather than reaching deep into tissue, and it's often used for lower-intensity, everyday skin-focused applications — people use it hoping to support a calmer, more even-looking complexion over time.

During a 15-minute Dahlia session, you're getting all four wavelengths blended together, with sensors in each SmartSegment adjusting intensity automatically. 630nm is the mildest part of that mix, working alongside the others rather than on its own. As with all of our red light sessions, this is wellness support, not a treatment for any medical condition — individual results vary.

Next up: 660nm, red light's workhorse wavelength. In the meantime, the First Wave intro session is still part of our Grand Opening Special — book a visit and see what 15 minutes of lying down can do.
