Hi Sky,
My fav web site is webmd.com uvb therapy they have a great detailed explanation on light treatments.
http://www.westcoderm.com/xtrac_laser.php
Also good site for xtrac laser therapy.
Light treatments are done in small increments 2-3 x's a week. The time is slowly added. This is done to prevent the areas from burn.
It takes time for light therapy to approach the deep down derm layers to stop the capillary veins from feeding the P. Cells.
Stay with the treatment as it is a hassle to go in so much. In the long run it will be worth it. To many give up 2 soon. Give it time as this is a fickle disease. Always seems to get worse before it gets better.
Also ask UR derm about
the xtrac laser treatment. Very new & works faster to heal P. Calls.
HAPPY NURSING. BABY IN TOW... How Lucky U R....
Peace & healing
(( hugs ))
