Brief Summary
The study device, Sculptra, is an injectable implant formulation of poly-L-lactic acid microbeads, approved by the FDA for treatment of facial fat loss (lipoatrophy of HIV disease). It is being used off-label by dermatologists to treat dermal defects, as a biologically active filler. Anecdotal evidence suggests that subjects' skin quality may improve as a result of poly-L-lactic acid injection. While this is not the primary goal of such treatments it is often seen and described as so called "Sculptra glow". Based upon the study doctor's experience global skin quality improvement includes radiance, smoothness and pigment uniformity as well as a decrease in skin redness and pore size. In this study we evaluate the existence of histopathological (microscopic examination of tissue) evidence that can explain the observed improvement of skin quality after poly-L-lactic acid injections. Specifically, we will use histopathologic techniques to investigate effects of Sculptra injections into human skin with regard to restoring skin health and epidermal thickness.

- Subjects who have taken acetaminophen 24 hours before treatment
- Subjects who have had fillers or botulinum toxin in the treatment area in the past 12 months
- Subjects who have had treatments with poly-L-lactic acid in the face at any time
- Subjects who have had any kind of facial dermabrasion, chemical peel, laser, or IPL treatment including superficial treatments for aesthetic reasons in the past 6 months or for the duration of the study
- Subjects who does not agree to avoid using tanning beds or intensive exposure to the sun 2 two weeks prior to each office visit.
- Subjects who have any dermatologic conditions including acne, rosacea, eczema, psoriasis, actinic keratosis, severe sun damage, infection or scars within the treatment area
- Subjects who have an active inflammatory process (skin eruptions such as cysts, pimples, rashes or hives) or infection within the treatment area
- Subjects who have any known cancer including skin cancers (basal cell carcinoma, squamous cell carcinoma and melanoma)
- Subjects who have had systemic corticosteroid therapy in the past 6 months or for the duration of the study
- Subjects with a known history of poor wound healing
