Preparing for Your First Session

• Adults: 30 seconds

Directions for Use

• Treat 2–3 times per week, leaving at least one full day between sessions.
• Treat only when any redness (erythema) has subsided and the skin has fully recovered.

A skin reaction (erythema/redness) typically appears 6–8 hours after exposure:

• No redness: increase exposure time by 20 seconds for the next session.
• Mild redness: if it clears within 24 hours, extend the time by 20 seconds for the next treatment.
• Noticeable redness: if the skin is still pink after 24 hours, keep the same time and wait for the colour to fade before treating again.
• Marked redness: if the skin remains very red, pause treatment until it returns to normal, then reduce exposure time by 20 %.

The Philips BU‑1S handheld UV‑B lamp is designed to be user‑friendly, versatile and highly effective in managing a range of skin conditions, including vitiligo and psoriasis. With regular use you can achieve healthier, more confident skin.
