Is this a normal scar or poor skill? (Photo)

This depends entirely on the type of procedure that was performed. This is no an uncommon (yet not ideal) outcome for a mastopexy, especially one that only has a scar around the areola.

Dear 8cjgkkkk,
I understand your concern. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Thank you for your question. It is hard to say, but most likely the scars stretched a little bit overtime. This can happen due to tension on the skin (especially if you have an implant). This can be revised with a scar excision and good aftercare - silicone scar treatment etc. good luck.
