TOPLINE:
, and more data on Black and Latinx populations are needed, according to a literature review.
METHODOLOGY:
- Understanding the efficacy and safety of cosmetic injectables in diverse skin types is important because individuals identifying as racial and ethnic minorities accounted for 18% of neuromodulator procedures and 22% of soft tissue augmentation procedures in 2020 in the United States.
- Researchers reviewed available literature on the usability and efficacy of neuromodulators and soft tissue augmentation in individuals with SOC because of the limited data available in these populations, particularly non-Asian, SOC populations.
- Overall, 88 studies in English were included, which were either dedicated to discussing safety and/or efficacy of injectables in SOC populations or enrolled more than 20% of participants from SOC populations.
- High-quality level I and II evidence was found in 50 studies, and 9940 patients were analyzed in this review.
TAKEAWAY:
- Studies considered high quality indicated that botulinum toxin is safe and effective for treating glabellar lines in Asians; tailored guidelines recommended specific strategies; and adverse events, such as eyelid issues, were more common in Asians.
- Hyaluronic acid fillers showed significant improvement in moderate to severe cases of nasolabial folds in Asians, and adverse effects like swelling and pain were mild to moderate — some cases of granuloma formation and vascular compromise have been reported.
- In Black individuals, botulinum toxin was well tolerated; hyaluronic acid fillers showed favorable safety, with mild to moderate adverse events; and measures like slower injections and subdermal techniques minimized risks.
- In Latinx populations, there was a lack of robust study data on safety and efficacy of botulinum toxin, whereas hyaluronic acid and poly-L-lactic acid fillers were well tolerated.
IN PRACTICE:
“Neuromodulators and dermal fillers are useful and safe as cosmetic and antiaging treatments in SOC populations, with the greatest amount of data supporting its use in Asian populations,” although more data on Black and Latinx populations are needed, the authors concluded. “During cosmetic consultations, physicians should consider the impact of different cultural beauty norms on the aesthetic goals of diverse patient populations,” they added.
SOURCE:
This study led by Shanice McKenzie, MD, from the Department of Dermatology, University of Southern California, Los Angeles, California, was published online in the Journal of Cosmetic Dermatology.
LIMITATIONS:
Most of the recent data and formal consensus guidelines on injectables in the review came from Asian countries, and there was “a relative paucity of research on Black and Latinx populations,” the authors noted.
DISCLOSURES:
The study did not receive any funding. Two authors declared serving as a consultant, investigator, and/or speaker for various companies; the rest had no disclosures to report.
