I had derma veil in Asia three months ago hoping to restore some facial volume I most likely lost from Ultherapy and other HIFU treatments previously. I found the result to be less noticeable compared with my previous Sculptra treatments (last treatment two years ago, 3 vials) and am hoping to get some Sculptra again. I worry it would contradict with the Derma Veil I just had. How long should I wait between the Derma veil and Sculptra treatments? Thank you.
