I am very keen to go through the INFINI as it should have min. downtime such as redness and swelling but aft running through the forum, I read many cases of long down time for redness and swelling and permanent grid marks. - what caused them? Are the above effects preventable? - when can one start putting on makeup? - how long does it take for redness and swelling to go away? - are the above negative side effects common? Thank you.
