I think that you can probably start wearing it after the glue peels off as long as it doesn't macerate the . But it is always best to ask your surgeon to see what he recommends.
Hello! Thank you for your question. It is common for scars to fully mature for up to a year. In the meantime, there are a few things that may help to ameliorate your incision/scar. The most proven (as well as cheapest) modality is simple scar massage. Applying pressure and massaging the well-healed scar has been shown to improve the appearance as it breaks up the scar tissue, hopefully producing the finest scar as possible. Other things that have been shown to add some benefit are silicone sheets, hydration, and topical steroids. In addition, avoidance of direct sunlight to the incision will significantly help the appearance as they tend to discolor with UV light during the healing process.
If unsightly scars are still present after approximately a year's time, other things that your surgeon may consider are intralesional steroid injections, laser, or just surgical revision of the scar itself.
Hope that this helps! Best wishes for a wonderful result!
Use of scar products
I personally don't advocate using them unless you appreciate some adverse changes in your scar. Why do it when the scars almost universally heal well in that location? But if you want to use it, best to ask your surgeon for advice on when to start since your surgeon is on the 'hook' if anything should occur during your recovery.
