308nm UVB Light Therapy for Vitiligo — Targeted Treatment at Home
Clinically Targeted 308nm UVB Therapy for Vitiligo
Vitiligo affects over 70 million people worldwide. Until recently, clinical-grade narrowband UVB phototherapy was only available at dermatology offices — requiring 2–3 visits per week, for months. Tendly Light brings the same 308nm targeted wavelength home, cleared by the FDA under 510(k) for safe, effective at-home use.
Why 308nm UVB Works for Vitiligo
308nm is the precise wavelength shown in clinical studies to stimulate melanocyte activity — the pigment-producing cells that vitiligo destroys. Unlike broadband UV devices, 308nm narrowband UVB delivers therapeutic energy only where it matters: directly to depigmented patches, without unnecessary exposure to surrounding healthy skin.
- Stimulates melanocyte regeneration in depigmented patches
- Clinically studied wavelength used in dermatology offices worldwide
- Targeted aperture system limits exposure to affected areas only
- No systemic side effects associated with oral medications
How Tendly Light Treats Vitiligo
Tendly Light delivers 308nm UVB energy through a 20.25 cm² treatment window — large enough to cover meaningful patch areas in a single session, small enough for precise targeting on hands, wrists, face, and body.
Recommended Protocol
- Start low. Begin at the lowest energy setting for your first 3 sessions.
- Protect surrounding skin. Use the included interchangeable shields to limit exposure to depigmented areas only.
- Treat 3–5x per week. Consistency is key — melanocyte regeneration requires cumulative UV exposure over weeks.
- Increase gradually. Advance one energy level every 3 sessions if no erythema appears within 24 hours.
- Track progress. Photograph treatment areas monthly to document repigmentation.
Most clinical studies report initial repigmentation signals at 8–12 weeks of consistent treatment.
Frequently Asked Questions — Vitiligo & 308nm UVB
How long before I see results?
Clinical literature reports initial repigmentation in 8–16 weeks of consistent 3–5x weekly treatment. Results vary by patch location, duration of depigmentation, and skin type.
Can I use Tendly Light on my face?
Yes. Use the smallest interchangeable shield for precise targeting. Always wear the included UV safety goggles during treatment near the eyes.
How is this different from a full-body UVB panel?
Full-body panels expose your entire skin surface to UV radiation. Tendly Light's targeted design means only the affected patch receives UV energy — reducing cumulative UV exposure to healthy skin.
Does it work on all skin types?
308nm UVB therapy has been studied across Fitzpatrick skin types I–VI. Darker skin types typically require adjusted dosing — starting at lower energy levels and increasing more gradually.
