Removing Bruise After Chin Implant and Neck Lipo?

Dear Guy from Puebla,
From your picture, I can't tell if the region just looks stained purple, or if there is visible localized swelling in the same region. If the contour is the same as the other side, and it just looks purple, we term this echymosis. Although it looks bad, it will go away on its own in 10 to 14 days. If there is localized swelling, then there is a small hematoma (blood clot) under the skin. These tend to liquefy about 10 days after surgery, and can be aspirated through a small needle. Follow up with your surgeon, as they have experience dealing with these issues and will help you get the best result.

Bruising is not uncommon with surgery in the subcutaneous plane.  I would recommend that you use an Arnica based product such as Bruise Pak oral dose tablets or Bruise Stick ointment. 

Bruising is very common, and there are several things that you could try. Arnica tablets and topicla gels can help to relieve some of the bruising. Also, try massaging the area with Mederma or gentle lotion. This may increase the blood flow to and from the area. Finally, cover-up make-up is fantastic these days and can hide almost everything without being too noticeable.
