Concerned. Arm lift incisions are getting thicker and look redder/irritated 9.5 weeks post op (Photo)

Hello SUZJUNCKIE1970 in Des Moines,
Thank you for reaching out with your concerns about the appearance of your arm lift incisions, which are becoming thicker, redder, and more irritated 9 1/2 weeks post-surgery. Your proactive approach in seeking advice is commendable, and I'm here to provide some guidance based on the information and photos you've shared.
Hypertrophic Scarring: Based on your description, it seems you might be experiencing hypertrophic scarring, a common reaction where scars become raised and red but are not infected. Scars indeed go through various stages of healing, and this phase can be a normal part of the process.
Silicone Gel and Sheeting: Continuing the use of silicone gel cream is a good strategy, as silicone is known for its effectiveness in managing scar appearance. Additionally, using silicone gel sheeting can offer further benefits. These sheets should ideally be worn continuously and can be held in place with arm sleeves, which are more comfortable than a garment and can be easily purchased online.
Garment Use: If you're still experiencing swelling, continuing to wear your arm compression garment is advisable. However, since you're beyond the initial 6 to 8-week post-surgery period, arm sleeves can be an alternative to keep the silicone strips in place and provide some support.
Future Scar Management: If, after 6 to 8 months, the appearance of the scars remains a concern, there are additional treatments you can consider. These may include steroid injections, 5-fluorouracil (5FU), microneedling, Morpheus8, dermabrasion, laser therapy, or potentially a surgical scar revision.
It's important to monitor the scars' progress and maintain regular follow-up with your plastic surgeon. They can assess the healing process and recommend specific treatments tailored to your case.
Please remember that while arm lift scars typically fade over time, they may not completely disappear. The key is finding the right balance between improving the scar appearance and managing expectations regarding the final outcome.
I hope this advice helps address your concerns and assists in guiding your ongoing scar management. Wishing you a smooth and successful healing journey.
Good luck, and take care.
Sincerely,
Dr. Katzen

Scars from an arm lift often become red after surgery until they completely mature with time.  Silicone scar gel is helpful, however I would also recommend silicone scar pads.  You can use the pads all day, or if you prefer not to have the pads on during the day, use the gel during the day, and the pads at night.  Massaging the scars is will also speed the maturation of the scars. 
The advantage of silicone scar pads are that they are more effective than the gel.  The disadvantage is that they are more cumbersome to wear.
Best of luck to you.

The two best approaches for scar management after brachioplasty are usually applying tape or silicone gel. Your scars may get worse before they get better. They tend to progress, getting better over 1 to 3 years. This should be followed by your plastic surgeon until the scars become more acceptable. There are other interventions that they may want to try, depending on your situation.
