UVB 311 nm phototherapy at DAGDERM

Phototherapy is an effective method of treating skin disorders by exposing the skin to controlled ultraviolet B (UVB) radiation with a wavelength of 311 nm. With precise light dosing, phototherapy relieves inflammation, reduces itching and promotes skin regeneration without the need for oral medication. The therapy improves patients’ quality of life by prolonging remission periods in dermatological diseases.

UVB 311 nm phototherapy is recommended for treating:

• psoriasis,
• atopic dermatitis,
• vitiligo,
• parapsoriasis,
• itching skin,
• lichen planus,
• seborrheic dermatitis,
• eczema and other dermatoses,
• urticaria,
• eczema,
• pityriasis rosea,
• acne

The therapy is also safe for use in children (from about 3–4 years of age), pregnant women, and breastfeeding women.

UVB 311 nm phototherapy is not indicated in people:

• with skin cancers,
• with diseases associated with UVB hypersensitivity,
• after previous treatment with ionizing radiation,
• taking drugs or herbs that cause photosensitization (e.g., ketoprofen, St. John’s wort),
• with severe liver disease,
• with eye disorders (cataracts, glaucoma),
• with coronary artery disease or after a recent heart attack,
• during active viral, bacterial, or fungal infections.

Qualification for phototherapy is always carried out by a dermatologist during the initial consultation.
