What can be done about this ridge from my tummy tuck scar? (Photo)

Hello and thank you for posting photos along with your question. From your photos, it appears that you have some fullness in the lower abdomen right above the scar. Liposuction to that area would likely improve the difference between the area above and below the scar. your scar has healed so nicely I don't know if you should go messing with the actual scar itself. Hope this helps and wish you all the best!

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.

Great question! Yes, I do think that you can have something done to help with the "ridge." Although your scar seems to have healed nicely (the skin component), the little bit of contour irregularity can be addressed with a scar revision by a plastic surgeon who will take into account the deeper layers during closure to create a more soft and flat area.. Best of Luck!

The slight irregularity or indentation from the tummy tuck scar is not uncommon when the scar is placed higher in the pubic area. I generally like to place the scar very low in the pubic area in order to prevent this type of problem and allow the scar to be concealed even if you wear low riding lingerie or bikini bottoms. Liposuction above the scar could be performed to even the contour. Please select a plastic surgeon board certified by the American Board of Plastic Surgery and preferably a member of the American Society of Aesthetic Plastic Surgeons, (ASAPS).

A scar revision would probably be best for you.  Speak to your Plastic Surgeon about your concerns.  Usually a scar revision can be done in-office under local anesthesia. Skin and fat should be removed in your case, in order to create a flatter appearance.  I hope this was helpful to you.  
Best Wishes,
