Retin-A cream on TT scar, Would this help with the scars appearance? (photos)

Dear Mother of Dobermans,every plastic surgeon has his own postoperative protocol which he recommends to his patients. I recommend my patients to use silicone scar gel twice per day. I would suggest you to discuss this with your plastic surgeon.Daniel Barrett, MD, MHA, MS

In general, scarring is a product of genetics. Some people are good scar formers, and others are poorer scar formers. I always minimize the scars to minimize the likelihood of poor scars. There is no one best therapy for scars. Silicone sheets, Mederma, and Bicorneum are reasonable and popular options.  I recommend that the scar therapy begin after the scars have healed and there are no open areas, which usually takes 4 - 6 weeks.

I personally wouldn't recommend Retin A cream. Best to run this by your PS and follow his/her instructions as there are a variety of scar creams and massage recommendations that vary between surgeons.

I would recommend a scar treatment plan that begins at one month if you are healing well. We use silicone scar sheeting and biocorneum topical scar compound, vitamin E oil and scar massage. You will continue treatment as incision is still pink and immature. Check with you PS on the treatment they recommend

You might get a better result using a scar cream.  There are several over the counter creams, plus vitamin E oil works well, also.  Rub in the direction of the scar.  Check in with your surgeon for instructions on scar management.
