Question regarding post-op induration/hard bruising following Vaser Hi-Def Abs. 12 days post. (photo)

It is still very early into your healing so you must try to remain patient. Bruising and #swelling are normal and usually increase slightly after the removal of any tape or foam. The bruising will decrease over 3-4 weeks, but may last as long as 6 weeks. The majority of the swelling will be gone within the first 3-4 weeks. However, it may take 6-9 weeks to disappear completely. The #lumps should diminish with time and self-massage may help. If not, your doctor can provide suggestions for this concern. In-office medi-spa treatments may be an option. But, it's best to be patient in the meantime as it is still early into your healing.
Swelling after #Vaser liposuction is not uncommon. Gentle #walking may increase circulation and help to alleviate swelling. But you must not strain or push yourself. Also, if you were provided a post-procedure #garment, be sure you are wearing it until prescribed otherwise by your doctor. The purpose of the post-procedure #garment is to provide some gentle #support and to reduce swelling. If it feels too tight or causes pain, take it off. Many patients wear the #elastic garment for several weeks after procedures, as directed by their doctor; some choose to wear it longer for several months for comfort.
The final results of the procedure are typically most noticeable 2-4 months following the #Vaser. So, you must have patience. The swelling will gradually diminish while the contours of the treated area(s) can continue to improve up to one year post procedure; becoming more apparent in appearance. If you have concerns about your healing, or pain that you question to be unusual, it is important to call your plastic surgeon to discuss these further asked to be examined. 

Your surgeon would have advised you on the MLD massage.  However, everyone has their own postop protocol.  Contact your surgeon to advise you.
Induration does occur post VASER. The massage is to minimise this and stimulate lymphatic flow.
Fibrotic tissue can be softened too.
Eventually getting back into exercise will also soften this.
