That sounds like a loaded question, but objectively speaking, no one is more prone to getting a burn, pigment has nothing to do with it. However, there is going to be some trauma to the incision skin edges whatever the liposuction technique. Only vaser generates heat from the cannula that must be mitigated by insulating the skin with a port protector and moist towel. And if that heat is excessive the incision can have some healing problems. Any patient can get hyperpigmentation at the point of entry of the cannula from friction trauma, but some patients will have a tendency to hyperpigment, and this is most noticeable in type IV and V patients as they have increased pigmentation to start with. A very fair skinned Black woman would be a type IV or V. If you are talking about end hit burns, where the vaser hits the undersurface of the skin and rests there too long, then a burn can occur with scarring. Fortunately this should be very rare nowadays as it is well known that you do not allow that to happen, you keep the cannula moving at all times and parallel not into the skin. So your question does not specify exactly what you mean by "liposuction burns", but these are two scenarios that could be included.
