Each surgeon will have their own recommendation on which cream is best to use. As always, any recommendation will depend on the patient's situation and skin. Discuss with your doctor which cream is right for you and your skin. I often recommend Dermatix and silicone sheeting.
I typically recommend some form of silicone for 3 months postoperatively for scar management - silicone gel sheeting is best for patients who can tolerate it. In those who cannot, I prescribe a liquid silicone formulation in a pump, for instance scar gel from QMedRx.
