Can I Have Restylane Lip Enhancement While I'm on Accutane?

Thank you for your question and for sharing your concern. For dermal fillers like Restylane or Juvederm, I would not recommend waiting any period of time after stopping Accutane or even while on Accutane. This would be very different if I was combining dermal filler's with any energy device that requires your body's ability to heal.

Hi Amelie,
Accutane should be stopped before having any cosmetic procedures or elective surgery.  Certainly elective fillers should not be injected while on Accutane.  Good luck and be well.

Accutane can cause some pretty awful changes to the lips including dryness, swelling and easier activation of cold sores. For this reason, adding another possible irritation to the lips isn't a good idea.
The other reason that this may be a bad idea is that if you do have complications of the filler it may be blamed on the accutane rather than the filler or vice versa. On the whole it is best to avoid fillers and accutane (and most other surgical procedures as well including lasers, peels and elective surgery).
