Hi,
As long as your active acne is well controlled, injectables are permissible and safe to administer while on isotretinoin. However, if active acne inflammation is still present, injectables may run the risk of aggravating the acne infection and inflammation, hence should best be avoided.
In general however, it may be prudent to focus first on completing the entire isotretinoin treatment course before commencing on additional invasive aesthetic treatments.
Hope this helps!
