Most plastic surgeons prefer that patients be off isotretinoin/Accutane for a period of time before elective surgery, but the exact waiting period varies. A common conservative recommendation is 6 months, while some surgeons may be comfortable with 3 months or sometimes less depending on dose, skin condition, and the type of procedure. For breast augmentation, I would generally want your skin, acne, and overall health to be stable before proceeding. The main concern with Accutane is not usually capsular contracture. There is no strong evidence that a short, completed course of Accutane directly increases capsular contracture risk with breast implants. The bigger theoretical concerns are wound healing, scar quality, skin fragility/dryness, and infection risk if active acne is present around the chest. Because this is elective surgery, ask both your dermatologist and plastic surgeon to agree on timing. Also, Accutane has strict pregnancy-related precautions, so make sure all required pregnancy prevention and testing rules have been completed before scheduling surgery. If your surgeon is cautious and asks you to wait 6 months, that is a reasonable and safe approach.
