Rolling scars occur due to pulling down of the skin surface by fibrous scar tissue beneath. Such scars are best treated by releasing the underlying scar tissue either by subcision (manual release using an inserted needle) or by fractional energy devices such as fractional CO2 laser.
While different types of dermal fillers differ in their composition, longevity, placement level and approved indications, in my opinion and experience, they are generally not the best treatment option for rolling or other types of depressed (atrophic) scars.
For rolling scars, it is better to opt for better and more long-lasting treatment options available.
Hope this explanation helps clarify the appropriate choice of treatment options for rolling scars.
