Brief Summary

Phototherapy, including ultraviolet B (UVB) and ultraviolet A (UVA) light, has been used to treat a number of dermatologic conditions. Psoriasis is one of the most common conditions treated with phototherapy, in which phototherapy is often indicated for extensive disease with contraindications for other systemic treatments. The mechanism of action of phototherapy for the treatment of psoriasis is not completely understood; however, it is known that UVB light induces apoptosis of pathogenic T cells and keratinocytes, which may reduce the overactive immune response and epidermal hyperproliferation. Phototherapy has shown some efficacy for other diseases, such as alopecia areata (AA) and polymorphous light eruption (PMLE). However, phototherapy is not always an accessible treatment option for patients due to cost or lack of time.

Detailed Description

Recent advancements in nanotechnology have led to the development of medical devices (lasers and LED devices) with unique phototherapy properties that emit radiation in the infrared wavelengths, allowing patients to benefit from the effects of phototherapy treatment in a more convenient way. Preclinical studies demonstrated the positive effects of infrared radiation exposure on the skin including, increased collagen synthesis and expression of transforming growth factor-beta1 (TGF-beta1). Other studies suggested possible antimicrobial effects from infrared radiation, with decreased colonization of Staphylococcus aureus, Escherichia coli, and Klebsiella pneumoniae on the skin after exposure. Compared to other fabric technology, such as Far-Infrared (FIR) fabric technology that reflects body heat, fabric made from Lumiton yarn converts external light in the UV and visible spectrum and emits light in the red and near-infrared spectrum for the body. Lumiton yarn absorbs energy from 350 nm to 600 nm (the light spectrum from UV to visible red light) and emit energy from 600 to 1000 nm (red, near-infrared spectrum). The Lumiton yarn contains red/NIR light-emitting dyes. The effectiveness of the technology is proportional to the intensity of the light, with its peak effectiveness under sunlight.

Arm && Interventions

Group	Intervention	Description
Polymorphous Light Eruption	Lumiton yarn shirt	Polymorphous light eruption participants will be provided a shirt made from the Lumiton yarn. The participants will be instructed to wear the shirt made from Lumiton yarn daily for 12 weeks both indoors and outdoors.
Psoriasis	Lumiton yarn sleeve	Psoriasis participants will be provided sleeves made from the Lumiton yarn to cover their arms. The participants will be instructed to wear the sleeves made from Lumiton yarn daily for 12 weeks both indoors and outdoors.
Alopecia Areata	Lumiton yarn hat	Alopecia areata participants will be provided a hat made from the Lumiton yarn. The participants will be instructed to wear the hat made from Lumiton yarn daily for 12 weeks both indoors and outdoors.

Primary Outcome Measures

Name	Time	Method
Disease severity - PASI	Week 12	Psoriasis Area and Severity Index-75 (PASI-75%) scores The percentage area affected by psoriasis is evaluated in the four regions of the body. In each region, the area is expressed as nil (0), 1-9% (score 1), 10-29% (score 2), 30-49% (score 3), 50-69% (score 4), 70-89% (score 5) or 90-100% (score 6).
Disease severity - photo	Week 12	Lesion photos
Disease severity - SALT	Week 12	Severity of Alopecia Tool (SALT) score The SALT score is computed by measuring the percentage of hair loss in each of 4 areas of the scalp-vertex (40%), right profile (18%), left profile (18%), and posterior (24%)-and adding the total to achieve a composite score.
