Hi there,
Thank you for your question. Liposuction is a cosmetic procedure that should be performed by a well trained, board-certified plastic surgeon (this can be found on the Singapore Association of Plastic Surgeons website saps.org.sg). In addition to this, they should be accredited by the Ministry of Health to perform liposuction (list is available from the MoH website).
Once you have determined that your plastic surgeon is accredited, you can then research his profile to determine his experience and expertise, as well as the technique of liposuction he/she performs. For example, the latest in high-definition liposculpting includes to use of the VASER.
Ultimately, the best way to decide after this is to seek a consult with your chosen plastic surgeon(s). They should perform a thorough assessment of your goals and desires, your current health, and the ability for you to achieve long term, satisfying results safely.
Hope this helps!
