Why does sunlight help psoriasis?
However, UVB is very effective at improving psoriasis, providing that the plaques are not too thick or reflective. So, sunlight can help psoriasis by virtue of the UVB wavelengths it contains. The UVB wavelengths in sunlight are also very effective at causing the production of vitamin D in the skin.
Can you do phototherapy at home?
Phototherapy. Phototherapy or light therapy is typically prescribed by a dermatologist. Phototherapy involves exposing the skin to ultraviolet light on a regular basis and under medical supervision. Treatments can be done in a health care provider's office or psoriasis clinic or at home with a phototherapy unit.

What is PUVA treatment?
PUVA treatment is both old and new. Psoralens are naturally occurring chemicals found in the seeds of various plants. For more than 2,000 years herbal teas prepared from these seeds have been used in combination with natural sunlight, which contains UVA light, to treat skin disorders in India and the Middle East.
What is PUVA therapy?
PUVA therapy consists of taking a medication called Psoralen (pronounced with a silent P, “soralen”) and subsequent exposure an hour later to Ultraviolet A (UVA) light. The name PUVA is an acronym from P in psoralen and UVA in Ultraviolet A light.
How does puva work?
PUVA therapy induces increased pigmentation in the skin and also increases the thickness of the epidermis. Both these effects diminish sensitivity to sunlight by decreasing the amount of ultraviolet light entering the deeper layers of the skin. This appears to be the mechanism whereby PUVA treatment is beneficial in disorders characterized by heightened sensitivity to sunlight, such as polymorphous light eruption and solar urticaria. The response of vitiligo to PUVA therapy is also partly due to this effect, but in addition PUVA is probably also affecting the function of immune cells in this disorder.
What are the side effects of puva?
1. Erythema (Redness) PUVA therapy, if given in sufficient dose, will produce redness of the skin in much the same way as does excessive exposure to sunlight.
How long does a pink rash last with Puva?
In addition, the redness lasts longer and can persist for a week or more. The dose of PUVA therapy you are given is selected to produce improvement in your skin disorder and at most a light pink color in your skin. The pinkness should not cause you any discomfort.
How is UVA measured?
The dose of UVA light is measured by a meter in joules per square centimeter, which is an amount of energy, and this is translated into a certain number of minutes of treatment. The output of the treatment units varies over time and different units emit different amounts of energy.
Does puva kill eczema?
PUVA treatment selectively kills off these cells and, fortunately, it can do this without producing any clinical evidence of harm to our normal immunity. Psoriasis, eczema, lichen planus, alopecia and mycosis fungoides are a few of the diseases that appear to respond to PUVA therapy via this mechanism.
What is the treatment for PUVA?
As in standard PUVA, the light exposure is gradually increased. Although not strictly PUVA, there is a treatment termed "extracorporeal photophoresis" whereby a patient's white blood cells are extracted from the bloodstream and then exposed to psoralen, followed by UVA, and then added back into the bloodstream.
How long does it take for a puva to work?
What Is PUVA Therapy? About 60-90 minutes after ingesting a weight-adjusted dose the 8-MOP, the patient's skin is exposed to fluorescent bulbs emitting UVA light energy. The precise amount of light exposure is specified by a physician in units of energy.
What is a puva?
PUVA Therapy Overview. PUVA is an acronym for psoralen and ultraviolet A. PUVA refers to the interaction of long wavelength ultraviolet light (320-400 nm) with a pharmaceutical molecule of plant origin, psoralen, producing a type of "photodynamic chemotherapy .". PUVA is useful in treating a number of human diseases.
How long does UVA exposure last?

Does puva damage DNA?
It is hypothesized that PUVA produces reactive oxygen atoms that lethally damage the DNA molecule and/or alters the chemical receptors of skin cells (epidermal cells) and certain immune cells (T-lymphocytes).
Is psoralen FDA approved?
Two forms of the psoralen molecule are currently medically useful: 8-methoxypsoralen ( 8-MOP, Oxsoralen, Methoxsalen) and 5-methoxypsoralen (not FDA approved). 8-MOP is the only psoralen available in the United States by prescription. 8-MOP can be given orally or applied topically.

How many UVA1 treatments per cycle?
High dose UVA1 refers to 130 J/cm 2 per single dose. The long-term risks of high dose UVA1 are uncertain so no more than 10-15 treatments per cycle and two cycles per year are recommended.

Can psoriasis be treated with UVA?
Some areas of skin disease may prove more resistant to PUVA than others, often because of prior sun exposure. Commonly, in patients with psoriasis, additional UVA is delivered to the lower limbs, nails and hands starting after about the 6th treatment.
Can you use psoralen on your skin?
Psoralen can be applied to small areas as a cream or lotion or the area to be treated can be soaked in a dilute solution 3mg/l (bathwater PUVA). The bathwater solution distributes the psoralen evenly within the skin. This is particularly useful for treating hand and foot dermatoses but some centres use bathwater PUVA for generalised skin disease to reduce nausea. Topical psoralens are extremely photosensitising, therefor very low doses of UVA must be used.
What is PUVA therapy?
PUVA (Psoralen and Ultra-Violet A) Therapy is one of the alternative methods to treat segmental vitiligo. The potent melanocyte stimulant is currently going obsolete choice due to poor outcome and limited future scope. It is a medical procedure, which involves exposing vitiligo lesions to the ultraviolet light after application of Psoralen (a chemical compound that is mostly derived from Psoralea corylifolia).
Is PUVA effective for vitiligo?
The PUVA method is most effective when vitiligo is limited to only one or two clearly defined patches. Many patients consider the therapy disruptive as it may require repetitive external applications of Psoralen. A patient is often asked to visit a healthcare facility for weeks to achieve desirable results. The degree of repigmentation achieved depends on the area affected, and the duration of the skin disorder. Some medications can be prescribed alongside the therapy to minimize allergic reactions.
Does PUVA cause nausea?
PUVA Therapy has shown lesser (and milder) side effects compared to Narrowband UVB Phototherapy for vitiligo. However, many experience nausea and itching after ingesting the psoralen compound.
