Suturing Technique for Less Scars?

The technique that leads to the best scars is a closure without tension on the skin and if it is placed in the natural wrinkle lines. Scar quality is also influenced by you ethnicity, healing ability, infection, etc. You will probably have an anchor scar reduction, and with this technique there's significant tension on the infamammary crease suture line due to the design of this operation. This incision is at higher risk for thick, raised hypertrophic scars. 

There isn't any one best technique or suture type that always produces the best scar, and your plastic surgeon will make the choice based on experience. Other factors such as tension on the skin edges are ultimately more important.
