What is Phototherapy?
Phototherapy, also known as light therapy, is a cutting-edge treatment that uses specific wavelengths of light to treat various skin conditions. This non-invasive procedure is highly effective for managing chronic conditions such as psoriasis, eczema, and vitiligo. By exposing the skin to controlled amounts of natural or artificial light, phototherapy helps reduce inflammation, slow down the rapid growth of skin cells, and alleviate symptoms.
Types of Phototherapy
Office-Based Phototherapy: Conducted in a dermatologist’s office, this type of phototherapy uses specialized equipment to deliver precise doses of ultraviolet (UV) light. It’s ideal for those who require monitored and controlled treatment for conditions like psoriasis, eczema, and vitiligo.
Home-Based Phototherapy: For convenience, home-based phototherapy units are available for patients who need frequent treatments. These units are designed to be safe and effective, allowing you to receive therapy in the comfort of your home under the guidance of your dermatologist.
How Does Phototherapy Work?
Phototherapy works by using UV light to slow down the rapid growth of skin cells, reduce inflammation, and help re-pigment the skin in conditions like vitiligo. The UV light penetrates the skin, decreasing inflammation. This leads to an improvement in symptoms such as itching, redness, and scaling.
…So why can’t you just go to a regular tanning booth? While phototherapy uses UV light, it is not intended to tan your skin. The doses of UV light used in phototherapy are carefully controlled and targeted to treat specific skin conditions without the prolonged exposure that causes tanning. The primary goal is therapeutic, not cosmetic.
Conditions Treated by Phototherapy
Phototherapy is commonly used to treat skin conditions such as psoriasis, eczema (atopic dermatitis), vitiligo, and some types of dermatitis. It can also be effective for certain types of itching (pruritus) and other inflammatory skin disorders. Always consult with a healthcare provider to determine if phototherapy is appropriate for your specific condition and circumstances.
Psoriasis: Phototherapy slows down the rapid growth of skin cells and reduces scaling and inflammation.
Eczema: It helps alleviate itching and inflammation associated with eczema.
Vitiligo: Phototherapy stimulates melanocytes, the cells responsible for producing pigment, helping to repigment the skin.
Itching: Phototherapy can also be effective for generalized itching (even if a rash is not present!). This requires discussion with your doctor.
Are You A Candidate for Phototherapy?
Phototherapy may be recommended if you have an inflammatory condition that hasn't responded well to topical treatments. Candidates should be in generally good health without conditions that contraindicate UV exposure, such as lupus or certain skin cancers. This is a very brief list of things we consider when thinking about phototherapy. Your dermatologist will discuss in much more detail!

Side Effects and Risks of Phototherapy
Phototherapy is generally considered a safe and effective treatment when administered under the supervision of a trained dermatologist. The controlled exposure to ultraviolet (UV) light is carefully calibrated to maximize therapeutic benefits while minimizing risks. Common side effects that patients might experience include redness, itching, and dry skin. These effects are typically mild and temporary, often resolving shortly after the treatment session.
However, as with any medical treatment, there are potential risks associated with long-term use of phototherapy. Prolonged exposure to UV light can increase the risk of premature skin aging, leading to wrinkles and changes in skin texture over time. More importantly, there is a heightened risk of developing skin cancer with extended phototherapy treatment. This risk underscores the importance of adhering to your dermatologist's recommendations and attending all scheduled follow-up appointments.
