Rejuran can be used together with skin boosters which are not cross-linked. Examples include Teoysal RD1 and Belotero hydro.
In fact, I often suggest combining rejuran & non-cross linked HA skin boosters to my patients for optimum results and efficacy.
I would advice a proper assessment to suggest the right treatment(s) for your skin erythema (redness) and scars. In my experience, a combined comprehensive approach will yield best and most cost-effective outcomes.
Hope this helps!
