Full-spectrum light, from UV to infrared, used with precision to regulate mood, synthesize vitamin D, support the skin and recharge energy levels.
Think of your phone: depending on the radio wavelength you pick up, you receive WiFi, 5G, or Bluetooth, radically different effects despite the same principle of transmission. Light works the same way with your biology. Each wavelength speaks to a different receptor, triggers a different biochemical cascade, produces a measurable and distinct effect.
UV-B (290–315 nm) activates a skin protein, 7-dehydrocholesterol, which transforms into pre-vitamin D3 then into active vitamin D. In Switzerland, between October and April, the sun is not high enough in the sky to trigger this reaction. As a result, 70% of the Geneva population is in subclinical deficiency by the end of winter.
Blue light (460–490 nm) reaches the melanopsin retinal ganglion cells, your "daylight sensors". They send a signal to the hypothalamus, which raises serotonin, suppresses daytime melatonin and sets your inner alarm clock like a Swiss watch. Red light (620–700 nm) penetrates 5–10 mm into tissues, stimulates cellular respiration and accelerates skin regeneration.
Our phototherapy protocols precisely calibrate each spectrum according to your goal: vitality, skin, mood or circadian cycle. This is not relaxation, this is physiology piloted by light.
Light often acts subtly but deeply. What you will observe week after week.
A gentle warmth on the skin. The eyelids perceive a golden light. Something in you opens, like the first rays of sun on a beautiful morning.
Mood stabilizes. Less irritability at the end of the day. Your skin appears slightly more radiant. Falling asleep is easier, the wake-up less harsh.
Your vitamin D levels rise. Background energy consolidates. The winter blues lose ground. Those around you notice something in your complexion and tone.
Your sleep-wake rhythm has stabilized. The skin has regained its texture. The Swiss winter no longer affects you as before, you have refilled your light reserves.
"Every November, I sank into a kind of fog, less motivation, chaotic sleep, dull skin. This year, it's the first time in ten years that I made it through winter without falling apart."
Phototherapy combines naturally with other technologies for amplified effects on mood, skin and energy.
Broad-spectrum phototherapy + 10,000 lux light therapy = complete action on the circadian axis AND on vitamin D synthesis. One sets the clock, the other refills the supply of light-derived nutrients.
Both technologies use light but at different levels. Phototherapy acts on the skin and rhythms. Photobiomodulation penetrates deeper to regenerate tissues. Together, they cover the whole organism.
Light stabilizes neurotransmitters (serotonin, dopamine). Neuro-relaxation regulates the nervous system. Combined, they create an ideal biological platform for emotional stability and stress resistance.
