UVB Light Treatment (Phototherapy)
UVB light treatment, also known as narrowband UVB phototherapy, is a medical procedure used to treat various skin conditions by exposing the skin to a specific wavelength of ultraviolet B (UVB) light under controlled conditions.
What is UVB Light Treatment?
UVB therapy uses a special medical device that emits controlled UVB rays (311–313 nm) to target affected skin areas. It helps slow down the excessive growth of skin cells and reduces inflammation.
Why is it done?
UVB light treatment is commonly used for:
- Psoriasis
- Vitiligo
- Eczema (Atopic dermatitis)
- Chronic itching (Pruritus)
- Certain types of skin rashes and inflammation
How does it work?
- UVB rays penetrate the outer layer of the skin.
- It slows abnormal skin cell production.
- Reduces redness, scaling, and inflammation.
- Helps restore normal skin pigmentation in conditions like vitiligo.
Procedure Steps
- Skin assessment by dermatologist
- Eye protection is provided
- Patient stands or sits in UVB chamber or targeted area exposure
- Exposure time is carefully controlled (seconds to minutes)
- Treatment is repeated 2–3 times per week
Benefits
- Non-invasive treatment
- No surgery required
- Effective for chronic skin diseases
- Improves skin appearance gradually
Side Effects (Usually mild)
- Skin redness (like mild sunburn)
- Dryness or itching
- Temporary darkening of skin
- Rare: blistering if overexposed
Recovery & Results
- No downtime required
- Improvement usually seen in 3–6 weeks
- Full treatment may take several months depending on condition
Important Note
UVB therapy should always be done under dermatologist supervision, as incorrect exposure can damage the skin.
