As UVB sessions help people like me heal faster there's also some disadvantages brought by this treatment. An overexposure to UVB radiation can cause sunburn and some forms of skin cancer. However the most deadly form - malignant melanoma - is mostly caused by the indirect DNA damage (free radicals and oxidative stress). In humans, prolonged exposure to solar UV radiation may result in acute and chronic health effects on the skin, eye, and immune system.[15] This can be seen from the absence of a UV-signature mutation in 92% of all melanoma.
UVB helps in the production of Vitamin D. Vitamin D has regulatory roles in calcium metabolism (which is vital for normal functioning of the nervous system, as well as for bone growth and maintenance of bone density), immunity, cell proliferation, insulin secretion, and blood pressure.
After a UVB treatment make sure that you observe the following do's and dont's:
1. DO make sure that you have a referral from you derma or doctor as they will know whether it is necessary for you to undergo the treatment.
2. DONT make you Derma or doctor prescribed you this treatment if it ain't really needed. Sometimes our desire to get healed immediately would make us want to have the extreme treatments or the higher dosage of medicines. Let our doctors decide, we don't have to put words in their mouth. They know what's best for us.
3. Make sure the one conducting the session is a licensed doctor or an authorized medical personnel.
4. DO apply sunblock to the areas that were exposed during the treatment.
5. DO avoid additional sun exposure for the day. Remember UVB is like standing under the sun for 20 minutes so there's no need to get exposed some more.
6. DO protect the eyes by wearing sunglasses with UV protection.
7. DO apply topical medications upon returning home.
8. DO call you attending derma if you should or should not continue your treatment. This is more patients that have more than 1 prescribed session. It is advisable to have a follow-up check-up with your derma so she can see your skin if there's improvement already.
9. DO call your attending derma when you experience any of the following within 24 hours:
a. Unusual or persistent pain
b. Burning
c. Blistering
d. Persistent Erythema ( redness of the skin, caused by hyperemia of the capillaries in the lowerlayers of the skin.)
e. Swelling
10. DO get the contact numbers of the Phototherapy lab of the hospital so you can contact them if you have further concerns.
