How Lumeria Works

The three steps

The Lumoscope: clinical-grade multispectral imaging

The Lumoscope is Lumeria’s at-home imaging device. In one standardized scan it captures four bands of light, RGB, near-infrared, UV, and polarized, measuring properties of your skin an ordinary phone camera cannot. That breadth is what makes Lumeria a true skin tracker rather than a photo app.

Each band has a job: near-infrared reads hydration, RGB quantifies redness, UV surfaces pigmentation and sebum, polarized light reveals texture, and high-resolution color mapping tracks lesions. Every term is defined in the glossary.

What each wavelength reveals

Ultraviolet (365nm) fluorescence

The technique dates to the Wood’s lamp, invented in 1903 by the physicist Robert W. Wood and a staple of dermatology ever since. It passes a mercury-vapor source through a nickel-oxide “Wood’s glass” filter that blocks visible light and lets through a narrow band of long-wave ultraviolet, roughly 320 to 400nm, peaking at 365nm.

That exact wavelength is not arbitrary. 365nm is the dominant emission line of a mercury-vapor lamp, and it sits in the UVA range that reaches into the epidermis to excite the skin’s natural fluorophores while carrying far less energy than the UVB and UVC that cause sunburn and DNA damage. Lumeria reproduces this clinical band with a calibrated 365nm LED rather than a mercury bulb and filter.

When 365nm light strikes the skin, certain molecules absorb it and re-emit the energy as visible light, a glow called fluorescence. Porphyrins produced by follicular bacteria (Cutibacterium acnes) fluoresce orange-red, mapping oil and clogged pores; epidermal pigment lights up sharply while deeper, dermal pigment stays muted, which is why a Wood’s-light exam accentuates surface melasma and hints at how deep a mark really sits. The net result: hyperpigmentation, sebum, and subclinical sun damage surface long before the eye can see them.

Polarized light

Cross-polarized light cancels the surface glare so the camera reads past the shine into the skin’s structure: the pigment network, vascularity, and the texture and pores just beneath a mark.

Near-infrared

Longer near-infrared wavelengths travel deeper than visible light, reading hydration and subsurface detail the surface alone can’t show. Together these bands turn a single scan into a set of objective, trackable biometrics.

Dermbot: AI that adds context

An interview, not just an image

A scan tells you what your skin looks like; it does not know that you changed climates, started a new product, or slept poorly all week. Dermbot runs a short 1:1 interview to collect habits, locality, and environment, then combines that context with your multispectral scan to produce relevant recommendations.

Continuous monitoring + dermatologist support

Lumeria stores each capture against your baseline so you get true longitudinal skin monitoring: progress tracking on 7, 30, and 90-day trends that shows whether a condition is improving, stable, or worsening. When something warrants a professional eye, Lumeria connects you with dermatologists, bringing objective data to the conversation.
