The device is a portable phototherapy light that emits narrowband UVB at 311nm, a wavelength commonly used in dermatology. This targeted UVB exposure can help reduce inflammation and modulate skin cell behavior in conditions such as atopic dermatitis, vitiligo and psoriasis. Use under medical guidance.
The lamp is intended for management of atopic dermatitis (eczema), vitiligo patches and psoriasis flare-ups. It is designed as an adjunctive phototherapy device to support skin health and recovery.
The product is a Class II medical device (Model KJR-JGSG-B-1, Brand: LASTEK) and carries CE, RoHS, ISO13485 and ISO9001 certifications. Safety classification listed as Type II BOEM/ODMA. Always follow the user manual and a healthcare professional's instructions.

Treatment frequency and session duration vary by condition, skin type and clinical protocol. Typical regimens are individualized by a healthcare professional. Do not self-prescribe exposure times—consult your dermatologist for a safe treatment schedule.
Possible side effects include temporary redness, itching, dry skin, or mild burns if overexposed. Long-term risks of UV exposure include photoaging and increased cancer risk; therefore use only under medical supervision. Stop use and seek medical attention if you experience severe reactions.
