If you’ve tried creams and pills for stubborn skin conditions and still see flare‑ups, you might have heard about PUVA therapy. It’s a type of phototherapy that combines a medication called psoralen with UVA light to calm down the immune response in the skin. Many people with psoriasis, eczema, or vitiligo find it faster than topical treatments alone.
First, a doctor gives you a low dose of psoralen – either as a pill or a cream. Psoralen makes your skin cells more sensitive to UVA light. About an hour later, you sit under a special lamp that emits UVA rays. The light reaches deeper layers of skin than UVB, which helps reset the skin’s growth cycle and reduces inflammation.
The treatment is usually done two to three times a week at a clinic. Each session lasts only a few minutes, but the total number of sessions can range from 20 to 30 depending on how your skin reacts. Over time, you’ll notice red patches fading, scaling lessening, and itching dropping.
Before you start, the doctor will check your medical history. If you’re pregnant, have a history of skin cancer, or take certain medications, PUVA might not be right for you. During the first few visits, you’ll get a small dose of UVA – the doctor will increase it slowly to avoid burns.
Protect your eyes with goggles that block UV light, and wear sunscreen on any areas not being treated. After each session, your skin may feel a bit warm or look slightly pink, but it shouldn’t blister. If you notice severe redness, swelling, or blisters, call your clinic right away.
Long‑term use can raise the risk of skin aging and skin cancer, so doctors limit the total number of treatments. Most patients finish a course within a year and then move to maintenance sessions or other therapies.
Do you wonder how long the results last? Some people stay clear for months after finishing PUVA, while others need occasional maintenance sessions to keep the skin calm. Pairing PUVA with moisturizers and gentle skin care can extend the benefits.
Cost and convenience matter too. Many insurance plans cover phototherapy, but it’s worth checking your coverage. If traveling to a clinic is tough, some centers offer home‑use PUVA devices, though they still require a prescription and regular check‑ins.
Bottom line: PUVA therapy can be a game‑changer for tough skin conditions when other treatments fall short. It works by making skin more responsive to UVA light, which slows down the rapid cell turnover that drives psoriasis and eczema. With proper dosing, eye protection, and follow‑up, most people experience clear, smoother skin without major side effects.
Thinking about trying PUVA? Talk to your dermatologist, ask about the exact schedule, side‑effect monitoring, and whether it fits your lifestyle. A clear plan and realistic expectations make the difference between a successful outcome and frustration.
