Yes that is what is supposed to happen after a couple of days. Remember the patch material is gentle – not like a band aide that you have to rip off the skin when you want to change it.
So you apply the patch or patches to the lower abdomen area, fress very firmly and make sure they are away from clothes rubbing – like a waist band. Some of the patches may start to curl at the edges as a couple of days go by and this is normal so dont be worried about it. Your skin will still be absorbing the nutrients.
Example: The best way to judge when to change is to apply the patch or patches on Monday morning and change on Thursday morning.
And after shower remember to press them firmly with a dry towel – press dont rub.
