Psoriasis and UV lamps

Medical phototherapy uses a controlled part of ultraviolet light to reduce overactive inflammation in psoriasis. It is different from using a tanning bed or an unregulated home lamp. Treatment may be considered when plaques are widespread or have not settled with topical care, while the eyes and unaffected skin need protection. A clinician checks the skin response and adjusts exposure to reduce irritation or burning. Light treatment is not suitable for every person, including some people taking medicines that increase light sensitivity.

Use only the device and schedule prescribed for you, and do not add extra sessions because a plaque remains visible. Follow instructions about eye protection and covering areas that should not receive light. Tell the clinic about medicines, previous unusual reactions to sunlight, a history of skin cancers, and any new mole or changing spot. Moisturiser can help dryness, but ask which products are suitable before a session. Keep appointments so the response can be checked and the plan refined.

Contact the treatment team if treated skin becomes intensely red, blistered, very tender, or persistently sore, or if your eyes hurt or become unusually sensitive after exposure. Stop and seek urgent advice for facial swelling, breathing difficulty, or a widespread reaction. A new or changing skin spot should be examined rather than repeatedly exposed to light. Arrange review if the plaques are worsening, cracking, or interfering with sleep or movement.

Ask which type of phototherapy is being offered, why it suits your psoriasis, how your skin will be monitored, and which medicines or products could increase sensitivity. Clarify eye protection, missed sessions, home-device rules, and the symptoms that mean treatment should pause.
