Downtime and bruising with swelling after thread lift? Can multiple parts of body be done at same time?

Thank-you for your questions. I counsel my patients that there is always a risk of bruising and/or swelling when a needle pierces the skin, such as during a threading procedure. However, in my experience, the amount of bruising and swelling is usually minimal. I often utilize a cannula (a very small, blunt-tipped tube) instead of sharp needles (which can traumatize tissues and injure blood vessels), in addition to other techniques to lessen the chances of bruising and swelling. Also keep in mind where on your body the threads are being inserted. For example, bruises can be challenging to conceal on your face, but most of the rest of your body can be hidden from view quite easily under your clothes. Fortunately, bruising and swelling eventually resolve with time. Like any procedure, you will have to weigh the pros and cons to decide if it's worth the cost. 

Downtime for thread lift is usually 2-4 days depending on how many threads are used and how many areas of the face are involved.  Also, very often it is done together with other procedures such as fat injections or others, in which case it could be longer.

Thread lift can have zero down days for most of the time. Unfortunately though no one can guarantee that . There are multiple patient , equipment , and operator's factors that may play a role. Typically speaking more than 90% of patient's don't bruise. 
If a patient bruises then it can take few days till it disappears. 
Hope this helps !!
