Daily Cosmetic Research Analysis
Three clinically oriented cosmetic studies stood out: two randomized controlled trials in rhinoplasty and facial massage, and a device-enabled, prospective comparative study enabling at-home intralesional steroid injections for acne. Collectively, they refine procedural choices (when to add DSN transposition; which manual tool to select) and expand access by demonstrating safe patient self-administration.

1. Effect of Depressor Septi Transposition on Preventing Tip Droop During Smiling in Tongue-in-Groove Tip Plasty: A Randomized Controlled Trial.
In a randomized trial (n=50), both tongue-in-groove (TIG) alone and TIG with depressor septi nasi (DSN) transposition reduced dynamic nasal tip droop during smiling over one year. There were no significant between-group differences in tip angle change, tip/alar position, nasolabial angle, or patient satisfaction.
Impact: Provides Level I evidence suggesting DSN transposition may not add benefit when TIG is performed, informing surgical decision-making and potentially reducing additional dissection and risks.
Clinical Implications: Routine DSN transposition may be unnecessary when performing TIG for plunging tip deformity; surgeons can individualize based on patient-specific DSN overactivity while minimizing operative complexity.
Key Findings
- Randomized comparison of TIG alone (n=25) vs TIG+DSN transposition (n=25) with 1-year follow-up.
- Both groups showed significant reduction in tip angle drop during smiling, but no significant between-group differences (p=0.518 for tip angle).
- No significant differences in tip position, alar position, nasolabial angle, or patient satisfaction; both groups improved similarly.
Methodological Strengths
- Randomized controlled design with predefined primary endpoint and 1-year postoperative assessment.
- Comprehensive secondary outcomes including objective angles and standardized patient-reported outcomes.
Limitations
- Single-center study with modest sample size (n=50).
- Potential measurement and performance bias inherent to surgical RCTs lacking blinding.
Future Directions: Multicenter RCTs with 3D dynamic imaging and stratification by DSN hyperactivity could refine indications; explore long-term functional and aesthetic durability.
BACKGROUND AND AIMS: Plunging tips caused by overactivity of the depressor septi nasi (DSN) muscle present common challenges in rhinoplasty. The tongue-in-groove (TIG) surgical technique has proven effective in correcting static tip drooping. OBJECTIVE: This study aims to assess the effect of DSN transposition on preventing tip drooping during smiling in TIG tip plasty. METHODS: This clinical trial was conducted at a tertiary academic hospital from April 2022 to July 2024. Fifty patients with plunging tips who were undergoing septorhi
2. Comparative Effects of Facial Roller and Gua Sha Massage on Facial Contour, Muscle Tone, and Skin Elasticity: Randomized Controlled Trial.
In a randomized trial (n=34), both facial roller and gua sha improved facial contour measurements over 8 weeks. Gua sha primarily reduced muscle tone (F −2.02 Hz; S −56.46 N/m), while the facial roller improved skin elasticity (R2 +8.6%, R7 +7.5%), supporting modality selection based on therapeutic goals.
Impact: Provides controlled, head-to-head evidence clarifying distinct physiological effects of two popular manual cosmetic modalities, enabling targeted, evidence-based recommendations.
Clinical Implications: Select gua sha when reducing hypertonicity or myofascial contribution is desired; choose facial roller when the primary goal is improving skin elasticity. Both can improve facial contour over 8 weeks.
Key Findings
- Randomized assignment to facial roller (n=17) vs gua sha (n=17) for 8 weeks, 10 minutes, five times weekly.
- Both interventions significantly reduced multiple facial surface distances (p<0.001 within groups).
- Gua sha reduced muscle tone (F −2.02 Hz, p<0.001; S −56.46 N/m, p=0.002), whereas facial roller improved elasticity (R2 +8.6%, R7 +7.5%, p<0.001); between-group differences were significant.
Methodological Strengths
- Randomized controlled design with standardized home protocol and objective biomechanical metrics (R2, R7, F, S).
- Multiple anthropometric endpoints capturing contour change.
Limitations
- Small sample size and short intervention period (8 weeks) limit generalizability and durability assessment.
- Lack of assessor blinding and no sham control may introduce expectancy or measurement bias.
Future Directions: Larger, blinded RCTs with longer follow-up and inclusion of objective imaging (3D surface scanning) to assess durability and dose-response; explore combined protocols.
BACKGROUND: This study aimed to compare the effects of facial roller and gua sha massage on anthropometric facial contours, muscle tone, and skin elasticity parameters during an 8-week intervention period. METHODS: Thirty-four women aged 20-50 years were randomly assigned to facial roller (n = 17) or gua sha (n = 17) groups. Participants performed the designated massage technique for 10 min, five times per week for 8 weeks. Outcome measures included facial surface distances (subnasale-to-sublobular distance, mid-point distance, labrale superius distance, jawline surface distance),
3. Intralesional triamcinolone for inflammatory acne: a comparative study of dose efficacy and investigation of a novel injection assistance device to enable self-administration of intralesional therapy.
Across two registered, open-label clinical trials, device-assisted patient self-injection of intralesional triamcinolone for inflammatory acne was as safe and effective as provider-administered injections. A higher dose (0.2% vs 0.1%) improved outcomes in more severe lesions, with no adverse events reported.
Impact: Introduces a feasible, safe pathway for at-home, provider-prescribed intralesional steroid therapy, potentially expanding access and reducing time to lesion resolution.
Clinical Implications: Clinicians can consider prescribing device-assisted self-injections for selected patients to accelerate resolution of inflammatory nodules and reduce scarring risk, with dose escalation (0.2%) for more severe lesions.
Key Findings
- Device-assisted patient-administered intralesional triamcinolone was comparable in safety and efficacy to provider-administered injections.
- Higher concentration (0.2% vs 0.1%) improved lesion resolution in more severe acne lesions.
- No adverse events were reported across all study arms.
Methodological Strengths
- Prospective, multi-arm clinical evaluation across two registered trials (NCT06170593, NCT06186596).
- Direct head-to-head comparison of self- vs provider-injection and dose-ranging assessment.
Limitations
- Open-label design without blinding; sample size and follow-up duration not specified in the abstract.
- Generalisability may be limited without detailed inclusion criteria and long-term outcomes.
Future Directions: Randomized, blinded trials with quantified time-to-resolution endpoints and standardized scar outcomes; usability and adherence studies across diverse patient populations.
BACKGROUND: Acne is the most common dermatologic condition in the U.S., but few treatments work for individual lesions. One effective spot treatment is an injection of low dose steroid into the inflammatory lesion by a dermatologist or other provider. However, this treatment is not readily available to most patients given limited access to timely in-office injections. OBJECTIVE: First, to evaluate the safety and efficacy of intralesional triamcinolone injection for inflammatory acne delivered by METHODS: Three sequentially enrolling, open label arms of study were performed across two clinical trials (NCT06170593, NCT06186596). The first two arms compared standard provider injections to device-assisted patient-administered injections of 0.1% triamcinolone into inflammatory acne lesions. A third arm was enrolled to compare efficacy of 0.1% vs. 0.2% triamcinolone delivered RESULTS: Patient-administered injections showed comparable safety and efficacy to provider-administered injections. Patients with more severe lesions reported improved lesion resolution at the higher 0.2% triamcinolone dose. There were no adverse events in any group. CONCLUSION: This study supports the feasibility of self-administered, provider-prescribed intralesional treatments for inflammatory acne. Home administration could expedite lesion resolution and reduce scarring risk.
