What should I do to make my areola incision scars heal faster? (Photo)

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.

Hello, Thank you for your question. I typically recommend either silicone gel or sheeting to my patients to assist in the appearance of scars. Every Plastic
Surgeon has their own recovery protocol. I'd recommend consulting with your
Board Certified Plastic Surgeon for their recommendations. 
All the best.

On evaluating your photos, it appears that you have hypertrophic  scars.  Mederma is similar to silicone sheeting but just a different form.  I would suggest continuing the Merderma or a similar product.  If the scar gets thicker or does not resolve, a small amount of Kenalog could be injected.  This should be injected into the scar only and not into the surrounding tissue.  More than one treatment may be needed.
