Now the so-called "seamless breast augmentation" is still breast augmentation with prosthesis, not breast augmentation by injection. It only uses advanced technology to reduce the surgical incision to less than 4 cm. Take breast augmentation through axillary incision as an example. The incision is generally selected at the armpit fold, and the surgical incision is reduced by endoscopic technique. After operation, intradermal suture was performed with extremely thin absorbable thread according to the arc of the original incision. After healing, due to the cover of wrinkles, you can't see scars without careful observation. However, traces will definitely exist. Depending on the degree of personal recovery, some people with scar constitution will look very white and abrupt, while others will look very flat.
