How much sunlight/UV therapy is safe to treat psoriasis?

Doctor's Answers 2

Hello Coco,

Thanks for the D2D. You are right that sunlight and UV therapy can indeed help to relieve psoriasis. You may have heard about dead sea treatment where people spend a few weeks lazing in the dead sea to treat their psoriasis. It is believed that it is the ultraviolet from the sun that helps in a large part to the improvement in psoriasis.

UV therapy is employed as part of medical treatment for psoriasis. You will require 2 or 3 treatments a week. There is a small increase risk of skin cancer with the treatment and generally, we not treat beyond 200 to 250 treatment sessions.

Natural sunlight is helpful but it is important not do develop a sunburn as this can aggravate and trigger psoriasis. 10 to 15mins in morning sun is probably a safe to avoid a sunburn. The skin damage from sun exposure is also cumulative, so the more often you do it, the more damage there is to the sun.

How do I know if my child has psoriasis?

Eczema is much more common in childhood compared with psoriasis. The inner elbow area or flexural area is also a more common site for atopic eczema. Psoriasis tends to affect more the extensors of the elbow and the onset is often in the later teens and twenties, although it can also occur in childhood. The diagnosis of psoriasis and eczema is usually made clinically. If you have any doubts, you can visit your doctor or dermatologist, who can give you a proper assessment of the rash.

Does facial laser treatment trigger psoriasis?

Thanks for the question. If you have a diagnosis of psoriasis, there is a possibility that certain treatments can aggravate it. With psoriasis, damage or injury to the skin can cause psoriasis to develop at the site of the injury. This is know as the Koebner phenomenon. Therefore, you do have to take care that the treatment is gentle and does not cause any trauma or damage to the skin. Likewise, for eczema, the skin is sensitive and more prone to external insults, so you should avoid treatment if the facial skin is still red or irritated as this can be more easily aggravate by treatment.
