1. Chronic skin toxicities in breast cancer survivors: a systematic review and meta-analysis of radiotherapy techniques.
Across 7 studies (n=2418) including 3 RCTs, IMRT was associated with significantly lower grade ≥2 chronic hyperpigmentation versus conventional RT. No consistent long-term differences in cosmetic outcomes or HRQoL were detected. Evidence was limited by small study numbers and heterogeneous reporting.
Impact: This synthesis directly informs technique selection in adjuvant breast radiotherapy, linking IMRT to reduced chronic skin toxicity while clarifying where benefits are uncertain.
Clinical Implications: Consider IMRT to mitigate chronic hyperpigmentation risk after breast RT, while counseling patients that long-term cosmetic outcomes and HRQoL differences remain inconsistent. Standardized toxicity and patient-reported outcome reporting is needed.
Key Findings
- IMRT reduced grade ≥2 chronic hyperpigmentation versus conventional RT (RR 0.39, 95% CI 0.17–0.89).
- No consistent long-term differences in cosmetic outcomes or HRQoL (EORTC QLQ-C30/BR23) were observed.
- Evidence base included 7 studies (n=2418) with 3 RCTs; most used 45–50 Gy in 25 fractions.
Methodological Strengths
- Comprehensive multi-database search and random-effects meta-analysis
- Inclusion of randomized controlled trials within the pooled evidence
Limitations
- Small number of contributing studies and variable reporting standards
- Inconsistent long-term cosmetic and HRQoL outcomes limit definitive conclusions
Future Directions: Prospective trials with standardized chronic skin toxicity and patient-reported cosmetic endpoints, longer follow-up, and direct head-to-head comparisons of RT techniques.
PURPOSE: This study assessed the impact of radiotherapy (RT) techniques on chronic skin reactions and health-related quality of life (HRQoL) in breast cancer patients, comparing conventional RT with modern techniques such as intensity-modulated RT (IMRT). METHODS: A comprehensive search was conducted in Embase, MEDLINE, and Cochrane CENTRAL from inception to April 26, 2024. Conventional RT, which uses 2D or 3D imaging to shape radiation beams without dynamic intensity modulation, was compared with alternate RT techniques for adjuvant breast cancer treatment. Primary outcomes included chronic grade ≥ 2 skin toxicities (hyperpigmentation, breast fibrosis, telangiectasia, edema, and atrophy/retraction) and HRQoL, assessed mainly with EORTC QLQ-C30 and QLQ-BR23 modules. Pooled risk ratios (RR) with 95% confidence intervals (CI) were calculated using a random-effects model. RESULTS: From 1305 screened studies, nine articles representing seven studies (2418 patients), including three randomized controlled trials, met inclusion criteria. Most studies used conventional fractionation (45-50 Gray in 25 fractions). IMRT was associated with a lower incidence of chronic grade ≥ 2 hyperpigmentation (RR: 0.39, 95%CI: 0.17-0.89, I CONCLUSION: IMRT may reduce certain chronic skin toxicities compared to conventional RT. However, consistent long-term differences in cosmetic outcomes or HRQoL were not observed. These findings are limited by the small number of studies and variability in reporting standards.
2. Short- and Long-Term Effects of Adding Topical Cosmetics to a Dermatological Procedure (Thermage): A Randomized Controlled Comparative Study Exploring the Synergistic Effects.
In a randomized study of 42 women receiving a single Thermage session, adding repair/anti-aging topical products improved TEWL, hydration, elasticity, density, fine lines, texture, and pores at 4 weeks, with side effects subsiding by day 1. Benefits were significantly greater with product co-use, indicating synergy.
Impact: Provides randomized evidence that targeted post-procedure skincare can enhance device-based anti-aging outcomes and barrier recovery, informing peri-procedural care protocols.
Clinical Implications: Incorporate structured postoperative skincare with barrier-repair and anti-aging actives after Thermage to accelerate recovery and enhance outcomes, while validating regimen specifics in larger trials.
Key Findings
- Randomized 42-participant trial showed greater improvements in hydration, elasticity, density, fine lines, texture, and pores at 4 weeks with topical co-use.
- TEWL improved only in the test (topical) group; post-procedure side effects subsided by day 1.
- Single Thermage session combined with repair/anti-aging products demonstrated synergistic benefits.
Methodological Strengths
- Randomized comparative design
- Objective device-based measurements and image analysis over 4 weeks
Limitations
- Small single-center sample and short (4-week) follow-up
- Blinding and detailed product composition/regimen standardization not described
Future Directions: Larger, blinded RCTs with longer follow-up, standardized topical regimens, and biomarker profiling to delineate mechanisms and durability.
BACKGROUND: Dermatological procedures improve skin changes caused by aging. However, few studies have focused on the effect of improving various skin characteristics compared with the concurrent use of cosmetics. We aimed to confirm changes in skin characteristics owing to anti-aging dermatological procedures in the short- and long-term and to determine the efficacy of the procedure when products with anti-aging and repair effects are used together. MATERIALS AND METHODS: We included 42 women (mean age, 47.667 ± 3.183 years) divided into a test (n = 21) and control (n = 21) group, with no history of dermatological procedures within 3 months of the test participation date. The dermatological procedure involved a single application of Thermage treatments, and products containing repair and anti-aging ingredients were used for the test group. The skin changes were assessed using device-based measurements and image analysis up to 4 weeks post-procedure. RESULTS: Post-procedure side effects were alleviated 1 day after the procedure, and transepidermal water loss (TEWL) improved when the products were used together. Skin hydration, elasticity, density, fine lines, texture, and pores improved at 4 weeks after the procedure. When the test product was also used, the improvement was significantly greater, and TEWL of the face improved in the test group only. Aging-related skin characteristics were improved by Thermage, and the combined use of test products and procedures with repair and anti-aging effects improved skin characteristics. CONCLUSION: Dermatological procedures and cosmetic products have internal and external anti-aging effects on the skin, respectively, resulting in synergy.
3. Retrospective Review of Superficial Serial Microdroplet Technique for Glabellar Filler.
In a 10-year single-practice retrospective series of 719 glabellar filler injections using a superficial serial microdroplet technique, only mild transient local reactions were observed, resolving within 2 weeks, with no serious complications reported in the series. One vascular occlusion case from an external injector trained in the technique was referred during the study period.
Impact: Addresses a high-stakes aesthetic risk area with real-world safety data for a specific technique, informing injector training and risk mitigation strategies.
Clinical Implications: The glabella remains a high-risk area; most injectors should avoid it. For advanced injectors, a superficial microdroplet approach may mitigate risk, but anatomy mastery, ultrasound consideration, informed consent, and emergency protocols (e.g., hyaluronidase access) are essential.
Key Findings
- Among 719 glabellar injections, only mild bruising, swelling, and bumps occurred, all resolving within 2 weeks.
- No infections, vascular occlusions, or granulomas were reported within the single-practice series; one external referral case of vascular occlusion occurred.
- Technique utilized a 30-gauge needle with superficial serial microdroplet placement in a high-risk vascular region.
Methodological Strengths
- Large real-world series over a decade with standardized technique
- Focused on a high-risk anatomical area where safety data are scarce
Limitations
- Retrospective, single-practice design without a control group
- Potential selection and reporting biases; generalizability may be limited
Future Directions: Prospective multicenter registries or controlled studies comparing techniques (needle vs. cannula; depth strategies), integration of ultrasound guidance, and standardized complication reporting.
BACKGROUND: Injecting fillers in the glabella is dangerous due to numerous arterial vessels connecting to the ophthalmic artery putting patients at risk for skin necrosis and blindness. OBJECTIVE: Analyze the incidence of side effects with a superficial microdroplet glabellar injection technique. MATERIALS AND METHODS: A retrospective review was done in a private practice of one board-certified dermatologist's patients' charts utilizing a superficial serial microdroplet technique with a 30-gauge needle to treat etched glabellar rhytides from 2013 to 2023. RESULTS: The review identified 719 glabellar injections performed on 23 men and 696 women with an average age of 69. There were reports of mild bruising, swelling, and bumps, all resolving within 2 weeks. There were no serious complications such as infection, vascular occlusions, or granulomas and no long-term or delayed onset complications reported. There was one case of a glabellar vascular occlusion referred to the author for treatment during the review period by an injector trained in this technique. CONCLUSION: Injecting filler in the glabella is high risk, with the possibility of causing skin necrosis and blindness. Even with a safer microdroplet technique, most injectors should avoid this area, and advanced injectors planning this treatment should have knowledge of the anatomy and an understanding of techniques to decrease the risk.
