Hi Awalk,
Sculptra is Poly L-Lactic Acid, the same material that Vicryl absorbable suture material is made of. It is injected and over time stimulates an inflammatory reaction that adds volume to the area injected. Sculptra is injected deep, below the dermis, and where possible just above the periosteum of the facial bones.
Fraxel penetrates at maximum 1.6mm which is well above where Sculptra is injected. If injected using improper technique, Sculptra can result in granulomas, but Fraxel should not have any effect on properly placed Sculptra or exacerbating complications from it.
Be well.
Dr. P
