I just saw this blogpost reporting that a study has been completed to see how well Sculptra works in darker skin types.
A question was whether darker-skinned patients would create too much collagen, causing hypertrophic scars and keloids. But it turned out that “they do very well with this product,” according to Dr. Mest, with new collagen forming more quickly than light-skinned patients without any unwanted side effects.
Good news indeed for people with darker skin types.
