Hi,
I think that this is possible but you'll have to use some code customization through the
show_default file of your
product view of your front-end template that you are currently using by editing this code which is displaying your product description :
Code:
<div id="hikashop_product_description_main" class="hikashop_product_description_main">
<?php
//DISPLAY the product description
echo JHTML::_('content.prepare',preg_replace('#<hr *id="system-readmore" */>#i','',$this->element->product_description));
?>
</div>
