Yes. YOUWEMED uses the same narrowband UVB wavelength (311nm) commonly used in home phototherapy devices. Our Philips specialized lamps deliver consistent output that is clinically effective for conditions like psoriasis, vitiligo, and eczema when used as directed.

Direct manufacturing and online distribution help reduce unnecessary costs while maintaining essential phototherapy features. We focus on what matters — effective UVB output, safety, and durability — without the markup of traditional retail or hospital supply chains.

Yes. Selected YOUWEMED models (including the BU-1,BU-1S,BU-10) use genuine Philips specialized UVB lamps, known for their stability and long lifespan. This ensures you get reliable 311nm narrowband output with every session.

Absolutely. YOUWEMED devices are CE certified and feature built-in safety mechanisms including automatic timers, dose control, and UV-blocking shields. We recommend consulting your dermatologist before starting any phototherapy regimen and following the included user manual carefully.

This therapy is commonly employed for conditions such as psoriasis, vitiligo, and eczema. During the treatment, the affected skin is exposed to UVB light for a specific duration, helping to slow the rapid growth of skin cells, reduce inflammation, and promote healing.

The core principle of the ultraviolet phototherapy device is to use specific wavelengths of ultraviolet light (mainly narrow-band medium wave ultraviolet NB-UVB) to regulate the immune response and cell growth in the skin. For vitiligo, UVB (especially NB-UVB) can stimulate the activity of residual melanocytes in hair follicles and skin, promote their proliferation and migration, and produce melanin, gradually causing the white spot area to discolor.

The main use of UVB lamps is as phototherapy lamp, meaning treating skin diseases with light. The diseases UV-B lamps treat are psoriasis, vitiligo, lichen planus, atopic dermatitis (eczema), and other skin diseases. Thousands of dermatology clinics around the world treat skin ailments using UV-B lamps.

UVB penetrates and damages the outermost layers of your skin. Overexposure causes suntan, sunburn and, in severe cases, blistering. After stopping the irradiation, the metabolism will return to normal skin color within 1-3 months. If you are worried about the skin turning black, you can cover the normal skin with a blackout cloth/opaque cotton cloth, or apply sunscreen (SPF30 or above).

Sure, but this is only a secondary and accompanying physiological effect during its treatment process, rather than the main therapeutic goal. The ultraviolet band emitted by medical phototherapy devices (especially NB-UVB, peak wavelength 311nm) precisely covers the effective band for synthesizing vitamin D. Therefore, during phototherapy, the skin does indeed synthesize vitamin D synchronously.
