Interim Data From Two Ongoing Investigator-initiated Trials Highlight the Role of Sculptra® and Restylane® in Addressing Aesthetic Changes Associated With Weight Loss Medications and Menopause

• New interim results from a six-month investigator-initiated trial (IIT) supported by Galderma, regarding the clinical sequencing of women in menopause, show the combination of Restylane Skinboosters™ and Sculptra drove meaningful improvements in skin barrier function, hydration and patient satisfaction, with the most pronounced gains in hydration – a critical factor for perimenopausal skin health – observed when using Restylane Skinboosters first¹
• New interim data from a separate IIT show the cellular composition of adipose (fat) tissue may be altered in patients experiencing aesthetic changes in the abdomen following medication-driven weight loss, offering a biological explanation for clinician‑reported volume loss beyond weight reduction alone, and underscoring the importance of including regenerative aesthetic treatments as part of the patients’ weight loss journey²
• These data reinforce Galderma’s continuous support of independent research, in order to deliver holistic, individualized and science-led solutions that address growing patient needs, such as aesthetic changes related to menopause and medication-driven weight loss

New interim results from a nine‑month clinical sequencing IIT of women in menopause conducted by Dr. Andreas Nikolis, both on the face and the décolletage, demonstrated that the combination of Restylane Skinboosters and Sculptra drove progressive and meaningful improvements in skin quality, with the most pronounced gains in hydration seen when using Restylane Skinboosters first.¹ Hydration is a critical factor in menopausal skin health, as highlighted in an international survey of peri- and post-menopausal women as within their top five skin concerns for face and their number one concern for body.^1,8,9 The data reinforce the relevance and synergistic effects of the two products, with Skinboosters driving faster extra-cellular matrix and elastin-associated effects to quickly deliver hydration and improvements in skin roughness, fine lines and other imperfections, and Sculptra delivering regenerative benefits across all three skin layers, helping to gradually restore volume, firmness, radiance and skin quality, and smoothing wrinkles and folds over time.^1,3-7,10-12 Results showed that facial hydration and measures of skin‑barrier function improved over time in both groups, and the improvements were mirrored by patient‑reported outcomes, with satisfaction scores rising consistently across the study and reaching high levels by Month 6.¹ Together, these data show that both treatment sequences contribute to measurable improvements in skin health in women during menopause, and they provide insight into how the treatment protocol may be optimized for this specific patient group.¹

Aesthetic changes associated with medication-driven weight loss: New insights on cellular changes underscore importance of regenerative treatments that work across skin layers New interim IIT data show that in patients experiencing aesthetic changes in the abdomen associated with medication-driven weight loss, the cellular composition of adipose tissue is altered, offering a biological explanation for the volume changes increasingly reported by clinicians.² This underscores the value of regenerative treatment approaches, to support a healthy-looking appearance following medication-driven weight loss.² The IIT, conducted by Dr. Sabrina Fabi, evaluated 20 female patients with mild-to-moderate skin laxity on their abdomen.² Interim results demonstrated a statistically significant, four‑fold reduction in adipose‑derived stem cells (ADSCs), the regenerative cell population responsible for maintaining healthy fat tissue, when compared to those who were not taking prescription weight loss medication.² Fibroblasts were preserved. These findings contribute to a broader understanding of how the skin profile in individuals experiencing aesthetic changes associated with medication-driven weight loss differs from those where changes are occurring naturally with age without having taken prescription weight loss medications, and highlight why patients may benefit from treatment plans that focus not just on replacing lost volume, but on supporting the tissues’ underlying regenerative capacity.^2,13 Galderma is well‑positioned to address these alterations across the face and body, given its expertise in dermatology, specialized range of injectable treatments and skincare products, and patient‑centric approach developed in close collaboration with leading healthcare professionals. Sculptra is the first proven regenerative biostimulator, backed by over 25 years of clinical use.^3-7 With a unique poly-L-lactic acid (PLLA-SCA™) formulation, Sculptra re-engages the skin’s renewal process, stimulating adipose tissue, collagen and elastin for healthy looking skin.^3-7 Over the decades, it has evolved into a versatile treatment that delivers regenerative benefits across all three skin layers, helping to gradually restore volume, firmness, radiance and skin quality, and smoothing wrinkles and folds over time.^3-7,12
