5 Common Myths and Misconceptions About Phototherapy – Debunked
If you’ve been diagnosed with a chronic skin condition like psoriasis, eczema, or vitiligo, chances are you’ve come across phototherapy as a treatment option. While this time-tested therapy is safe and highly effective, many people hesitate to start because of outdated or inaccurate information.
At Phothera, we’re on a mission to simplify chronic skin care. That includes clearing up confusion and empowering you to make informed choices. In our latest video, we break down the 5 most common myths about phototherapy—and the real facts behind them.
Let’s dive in.
Myth 1: Phototherapy is the same as tanning
Reality: Phototherapy is not the same as using a tanning bed.
While both involve UV light, phototherapy uses narrowband UVB light, which is targeted and medically controlled to treat inflammation and overactive skin cells—not to tan the skin. Tanning beds emit UVA light, which penetrates deeper and can increase the risk of skin cancer without offering therapeutic benefit for conditions like psoriasis or eczema.
Bottom line: Phototherapy is a medical treatment, not cosmetic exposure.

Myth 2: Phototherapy is outdated or ineffective for severe cases
Reality: Phototherapy is still one of the most effective treatments for chronic skin conditions.
It’s been used for decades because it works—safely and reliably. In fact, the recent LITE Study, the largest trial of its kind, confirmed that home phototherapy is both safe and effective for managing psoriasis. Most patients see significant improvement in just a few weeks.
This is not outdated medicine—it’s evidence-based care that continues to evolve.

Myth 3: It’s only available in a clinic and is too complicated
Reality: Phototherapy can be done at home with a prescription.
Thanks to devices like those from Phothera, patients can now receive prescribed, provider-guided phototherapy from the comfort of their home. Our ClearLink Controller in Guided Mode ensures the treatment is delivered safely and consistently, using provider-programmed settings to match your condition and skin type.
Home phototherapy is ideal for people with busy schedules or limited access to dermatology offices—offering convenience without compromising care.

Myth 4: It takes too long to see results
Reality: When done under medical supervision, a majority of patients begin seeing clear skin in just a few weeks, with a recent clinical study showing that 82% of psoriasis patients saw nearly clear skin at just 5 weeks.
With controlled dosing and proper monitoring, phototherapy can be used safely over time to manage flares and maintain clearer skin.
Myth 5: It’s not covered by insurance and is too expensive
Reality: Phototherapy, including at-home devices, is often covered by insurance.
Many insurance plans cover home phototherapy when prescribed by a provider, especially if you’ve already tried other treatments. At Phothera, we work with your insurance provider and handle the paperwork to make the process as smooth as possible.
