Vasersmooth. Bruise getting so much worse? I'm nervous about skin necrosis, and if this is the beginning stages. (photo)

Hi, this is normal. Since your procedure is only 5 days ago, redness is usually the first stage of bruising followed by blue, purple, and finally, the healing stage of green and yellow. Looks like most of your bruising are blue and purple, the healing stage won't be too far.
Please do remember that most of the #swelling and #bruising will resolve in the first two weeks, although some may persist for 6–8 weeks. If you have any more concerns at all about your healing process, do not hesitate to contact your surgeon.

I hope your concern was addressed. #RealSelf100

It is normal to have fluctuation in bruising as fluid/swelling shift when you reposition during sitting and lying down. Purple to darker purple to faded purple to greenish to yellow and then back to normal is the usual progression. Legs take longer to get rid of swelling and bruising because they are almost always in the dependent position. Leg elevation, arnica and bromelain supplements, and wearing the garment 24/7 for 6-8 weeks (except when showering) should help to hasten the healing process. From your photos, it does not appear to be the beginning stages of skin necrosis, but bruising.
