Tummy tuck and breast scars not healing well after 3 months of surgery. (photos)

Abdominoplasty scars can be quite complex, ranging from the simple hypertrophic scar to a multiplane inflamed keloid. Pigmentation, discoloration, chronic inflammation, scar visibility can all occur in the short term. We begin each treatment with combination therapy using Yellow broadband BBL, Vbeam, fractional erbium, intralesional IIT, and scar modulation. Start with a combination of Plato's Scar Serum massaged twice daily after one week of epithelialization followed by Luminase/Exfolase. Scar consultation and revision may be recommended.

Scars remodel for one year after surgery. It is still too early to really judge what the final result will be. 

Thank you for sharing your question and photographs and I see your areas of concern.  Incisions can heal differently based on a number of different factors including tension on the skin surface and the type and location of sutures used.  It appears that your tummy tuck may have had some small superficial separations or stitch abscesses while your own breast has some hypertrophic scarring present.  I would discuss with your surgeon possible treatment options to maximize the scars' appearance and I have attached a link below with additional information.  Best wishes.
