Cosmetic procedures doesn’t mean going only for surgical interventions. Most frequently people undergo non-invasive cosmetic procedures which include:
-injected botulinum toxin and fillers (against wrinkles)
–laser and other light energy sources (Intense Pulsed Light (IPL)…)
-fat reduction (cryolipolysis)
This study was done to measure the safety of these cosmetic procedures performed by dermatologists
-US propsective study done in 8 geographical areas
-evaluation of cosmetic procedures over several months by 23 dermatologists primarily focusing on cosmetic procedures
–detection of adverse events (AE) was done done by: doctors and staff, self-reporting by patients and phone follow-up.
-A total of 20399 cosmetic procedures were done during this period
–Adverse events (AE) were found in 48 cases which amounts to a rate of 0.24%
-No serious AE was reported
For each procedure group the results are the following:
–Lasers: out of 7991 procedures, 7AE were found (rate=0.99%). The most common AE was post-inflammatory hyperpigmentation
–IPL 500-1200nm: out of 596 procedures, 2AEs were detected (rate=0.34%). The most common AE was hyperpigmentation
–Radiofrequency: out of 461 procedures, 1AE was found (rate=0.22%). The AE was a burn
–Botulinum toxin injection (Botox): out of 6200 procedures 2AEs were found (rate=0.03%). The AEs were lump, nodule, beading
–Fillers injection: out of 4430 procedures, 23 AEs were found (rate=0.52%). The most common AEs were lump, nodule, beading.
–Cryolipolysis: 1 AE was found out of 254 procedures (rate=0.39%). It was persistent dysesthesia
–Ultrasound: out of 467 procedures no AE was found
-Lighter cosmetic procedures appear to be very safe when done by dermatologists.
-The occurrence of adverse events was less than 1% and according to the authors none of the procedures done in this study induced serious side-effects. One can however wonder what happened with the case of cryolipolysis-induced persistent dysesthesia
In our opinion, such results could be extended to plastic surgeons who also focus mainly on the skin as part of their training
In the end, all physicians with the proper training can do these procedures.
