I have seen on Dr Rullan's website that they claim the more bruising, the more beneficial the results. This was also reiterated on other sources when I tried educating myself, seen below:

"Many people experience bruising with this procedure this is actually a good thing, as the platelets which are deposited in the skin as part of the bruise help grow collagen, thereby helping to prop up the treated acne scar."

Can anyone confirm that this is true?
