There are lots of ways to minimise scarring.

1.Choice of technique. You can elect a minimal scar technique. These techniques are; a) liposuction alone or b)"vertical " breast reduction techniques.
All these choices are open to you but the key is to understand how appropriate those choices may be for your individual needs. For instance a decision about liposuction is influenced by age (younger women's breast have more dense glandular tissue and are therefore more difficult to reduce with liposuction) and how much drooping of the breasts is present .If you have significant drooping you may need your nipples repositioned upwards as well as the weight of your breast reduced  which may not be able to be achieved by liposuction alone. Everyone is different and you need individual assessment and advice.

See this video from Dr Burt around this topic below.

2.Before and after a reduction procedure you will routinely get advice on scar management techniques to get any scarring produced to settle as favourably as possible.
It is important to understand that for most women who decide to have a breast reduction the severity of their symptoms (usually neck, back,shoulder pain  etc.) mean  any scars resulting from the breast reduction procedure they choose  are  acceptable to them as a trade off  for being symptom free.

This is the key decision in considering whether breast reduction is right for you
