Frequently Asked Questions
How many sessions of phototherapy are usually needed?
Most conditions require regular sessions two to three times a week over several weeks to months, with improvement typically noticed after 15-20 sessions; your dermatologist will tailor the course to your response.
Does phototherapy hurt?
No, the treatment itself is painless, though some redness or mild warmth in the treated skin similar to mild sunburn can occur afterward.
Is phototherapy safe for long-term use?
It is generally safe under medical supervision, but cumulative UV exposure over years is monitored to minimize long-term skin aging or skin cancer risk, especially with PUVA.
What precautions are needed on PUVA treatment days?
You should avoid direct sunlight and wear UV-protective sunglasses for the rest of the day after PUVA sessions since the skin and eyes remain light-sensitive.
Will my skin condition come back after phototherapy?
Some conditions like psoriasis and vitiligo can relapse over time, so maintenance sessions or other therapies may be recommended by your dermatologist to sustain results.
