Hello Tummy_08, Thank you for reaching out with your concerns. It's understandable to be worried about any unexpected changes following surgery. While it's uncommon for stretch marks to develop directly as a result of a tummy tuck procedure, it's possible that they may have been present but not as noticeable before the surgery. The tightening of the skin during a tummy tuck can sometimes bring out existing stretch marks that were previously hidden. The appearance of dark red stretch marks in the weeks following surgery can be concerning, but it's essential to address them with your plastic surgeon. They can provide a professional assessment of the situation and offer guidance on the best course of action. In the meantime, continuing to moisturize the area with cocoa butter as you're doing may help improve the skin's elasticity and reduce the visibility of the stretch marks over time. I recommend scheduling a follow-up appointment with your plastic surgeon to discuss your concerns and explore potential treatment options. They can provide personalized advice based on your individual situation and help alleviate any worries you may have. Take care, and best wishes for your recovery. Sincerely, Dr. Katzen
