Hi M,
Practicing in Encino, CA and seeing patients daily from Beverly Hills, Hollywood, and LA, I was reluctant to use Sculptra when it first came to the market in 2000 as I cannot afford to have lumps and bumps in my patients, many of whom are in front of film, TV, and still modeling cameras.
Fortunately, by 2008, the reasons for the formation of these lumps and bumps were understood, and preparation of the product as well as injection techniques and patient choice have resulted in a much lower incidence of lumps. I agree with what my colleagues have said here, particularily Dr. Weiner.
I began using Sculptra in late 2008 after attending a meeting where the world's experts were demonstrating their techniques for injecting Sculptra. I leaned over the to physician next to me, a young, beautiful, brilliant cosmetic dermatologist and whispered, "What do you think about this Sculptra?", and she replied, "I've had it myself!" That was the "straw that broke the camel's back for me, if this well educated, high profile dermatologist trusted the material in her own face, that was enough for me.
I have not seen any visible nodules or lumps in the hundreds of patients that I have treated with Sculptra since 2008. We have seen a handful of patients with a smaller than pea sized palpable bump, all of which disappeared spontaneously on their own. I am a clinical instructor for physicians wishing to learn how to use Sculptra.
When used properly, Sculptra is a very safe volume replacement treatment. Good luck and be well.
Dr. P
