I have done 2 sessions of Sculptra. The first one, I did not do any pre-injection prep to minimize bruising. Two days later, it looked like I had allergies, very red circles on my eyes. Was able to cover with make up. For the 2nd treatment, I read up and this is what I did to minimize the bruising. The day before, I took 1200 mg of Vitamin C, and Arnica Montana the pm before the treatment. The day of the treatment, I again took the 1200 mg of Vitamin C, and took the Arnica Montana, 3x a day, and applied Vitamin K cream to the face when I was massaging it. Day after treatment, same thing. I am still using the Vitamin K cream for the massaging. This treatment has many more injection sites, and it is still sore, but I did not have ANY bruising at all. So hope this helps others. And if my face looks anything like it did after the injections that day, when it starts to do it's magic...I will be really happy. Sculptra is definitely a patience product with long last effects.
