Is it too late to restart silicone strips on my BA scars?

Best Scar Management is important to minimize or completely hide from view, the telltale signs of your surgery—namely, scars. Both you and your surgeon want you to have the most minimal scarring possible. There are many possible causes for scars that are enlarged or not healing well. Unsightly scars are most commonly due to genetics, underlying medical conditions, or improper scar/wound care. The last part is very important and patients can make a noticeable difference in their scars’ appearance by following best scar management practices. I have attached a link to help you. 

Thank you for your question.  After a full year, your scars have largely matured and will see little benefit from conservative treatments, such as taping or silicone sheets.  Depending on your scars' appearance, steroid injections or a scar revision may be of the greatest benefit.
