Don't worry, what you have donewill have absolutely NO effect on your response to the Sculptra injections!
Sculptra is a wonderful product and will provide two years of natural looking results. Using a topical hydrocortisone cream will have no effect on deeper Sculptra injections. Now you can wait for the next weeks wile the collagen builds in your skin and enjoy great results.
I fully agree with Dr Echavez. The Sculptra is placed at a level much deeper in the skin than the hydrocortisone would ever reach. It sounds like the hydrocortisone resolved the irritation at the injection sites so now you can look forward to achieving a your results from Sculptra. Best wishes.
The use of topical hydrocortisone should not have any effect on your Sculptra results. The Sculptra is placed in a level deeper than the hydrocortisone would reach.
