What to Look For

FDA 510(k) Clearance (United States): Indicates the device has been reviewed and cleared as a Class II medical device specifically for treating conditions like vitiligo and psoriasis.
CE Marking (European Union): Confirms conformity with health, safety, and environmental protection standards for medical devices.
Health Canada License or equivalent regulatory approval in your country.

Why This Matters

Regulatory clearance is not a rubber stamp. It means the manufacturer has submitted evidence to demonstrate:

The device emits the claimed wavelength consistently.
It is safe for home use under prescribed protocols.
It is effective for its intended indications (vitiligo, psoriasis).

Without this clearance, you have no assurance that the device delivers therapeutic light, that it won't cause burns, or that its components are safe for skin contact.

The 2026 Perspective

Recent studies emphasize that device quality varies significantly within the same technology class . Regulatory status is the only independent, third-verified indicator of minimum safety and efficacy standards.

Red Flags:

"Not evaluated by the FDA"
"For cosmetic use only" or "Not intended to treat medical conditions"
"For research purposes"
No regulatory markings visible on the device or in documentation
