Fractional microneedling radiofrequency in striae alba: Do growth factors add value?

The role of the beautician in reducing striae

INTRODUCTION

Striae distensae are a permanent skin defect that can affect 50%-90% of the population. The appearance of the changes resembles spindle-shaped skin bands. The skin in this area is wrinkled, thin and looks like a scar. Most often, the changes are found on the skin of the abdomen, buttocks, breasts, thighs, and back. The appearance of striae means that the skin in this area has no hair follicles, sebaceous, and sweat glands. This skin is flabby, not very elastic and, what is very characteristic, the pigmentation of the skin affected by striae is much lower than in healthy skin. Cosmetology in the 21st century is developing very dynamically, new technologies are being developed, new cosmetological devices are being created and combined with treatments that have been known for a long time. Today's science offers hope for people who have struggled with reducing striae for many years and nowadays, nothing is impossible.

AIMS

The objective of this article is to provide information about cosmetological treatment used to reduce striae.

METHODS

In this article, we reviewed the published literature, article published in peer-reviewed journals.

RESULTS

Today's cosmetology offers a wide range of numerous treatments, but the best results are achieved through a synergy of two or more treatments. But we should not forget that we should respond to each customer individually.

CONCLUSION

The striae are not a problem that should be ignored. The beauty therapist is able to reduce them and help the client to improve the appearance of their skin.

Microneedling Therapy for Striae Distensae: Systematic Review and Meta-Analysis

INTRODUCTION

Striae distensae (SD), linear scars of derma, caused by disproportionate skin stretching, which indicates a cosmetic problem and even endangers individuals' psychosocial health. Microneedling, representing a relatively new procedural therapy, has shown brightening but diverse results in the remedy of SD. Our study systematically investigates and further evaluates the efficacy of microneedling for SD.

METHOD

This study was conducted following the PRISMA guidelines. According to the preplanned search strategy, four electronic databases were comprehensively searched for eligible clinical controlled studies. Standardized mean difference (SMD) and odd ratio (OR) with 95% confidence intervals were calculated for continuous data and dichotomous data, respectively.

RESULTS

According to the predetermined criteria, eleven eligible articles of six RCTs and five non-RCTs were included. Concerning clinical improvement, a significant difference was observed in the microneedle radiofrequency treatment subgroup (SMD: 0.57, 95% CI 0.20-0.94, P = 0.003). The pooled result of the second subgroup revealed that microneedling and lasers producing almost comparable effectiveness for treating SD with no significant difference (P = 0.35). The analysis result of the third subgroup of microneedling versus non-laser therapy indicated significant difference at the 5% significance level (SMD:1.01, 95% CI 0.51-1.51, P < 0.0001). With regard to patient satisfaction, the pooled estimate concluded that participants' satisfaction with therapeutic effect between MRF and laser group was comparable (P = 0.26), whereas microneedling exhibited significant superiority than both laser (P = 0.04) and non-laser treatments (SMD: 0.95, 95% CI 0.52-1.38, P < 0.0001). Occurrence of post-inflammatory hyperpigmentation (PIH) was not obvious in microneedling therapy compared to other treatments, and a statistically difference was observed (P = 0.0003). Microneedling treatment caused significant pain compared with laser therapy (P < 0.00001).

CONCLUSION

This systematic review and meta-analysis has provided initial evidence of the efficacy and safety of microneedling technology for SD.

Fractional microneedle radiofrequency treatment for enlarged facial pores: A real-world retrospective observational study on 75 patients

OBJECTIVE

This study aimed to analyze the clinical results and influencing factors of the fractional microneedle radiofrequency (FMR) treatment for enlarged facial pores on different facial sites.

METHODS

The clinical data of patients with enlarged facial pores who underwent FMR treatment from January 2019 to December 2020 were collected. The efficacy and complications of FMR for enlarged pores in different facial areas were retrospectively analyzed. Univariate and multivariate logistic regression analyses were used to explore the clinical factors related to the efficacy of FMR after the first treatment session.

RESULTS

Totally, 75 patients with enlarged facial pores were included (full-face FMR for 45, nasal FMR for 58, frontal FMR for 45, and cheek FMR for 72 patients). All patients received more than one treatment session, two patients received five treatment sessions, and the mean number of FMR session was 1.7. The moderate to excellent improvement rates in patients with nasal, frontal and cheek enlarged pores after the first session were 13.8%, 8.9%, and 11.1%, respectively. The improvement rate rose with the increasing number of treatment sessions. Multivariate logistic regression analysis revealed that long pulse-width (300 ms) was positively associated with clinical efficacy after the first session (OR = 22.4, 95% CI [2.0-250.4], p = 0.012), compared with the short pulse-width group (100-200 ms). The main adverse effects after FMR were transient pain, erythema, and edema. A minority of patients developed acneiform eruption.

CONCLUSION

This study confirms that FMR is safe and effective in improving enlarged facial pores. The pulse width is associated with the improvement of nasal enlarged pores.

Radiofrequency Microneedling: A Comprehensive and Critical Review

BACKGROUND

Many studies have evaluated radiofrequency microneedling (RFMN) in various dermatologic conditions. However, the efficacy and safety of RFMN, and how it compares with other energy-based devices in a clinician's armamentarium, remains unclear.

OBJECTIVE

To review higher-quality evidence supporting RFMN and the dermatologic conditions which it can be used in.

MATERIALS AND METHODS

A search was conducted in MEDLINE and EMBASE from inception to May 13, 2020, using the terms: "radiofrequency microneedling" OR "fractional radiofrequency" OR "radiofrequency needling" OR "radiofrequency percutaneous collagen induction." Only randomized, split body or blinded studies with original data on humans were included. Non-English or non-dermatology-related studies were excluded.

RESULTS

Forty-two higher-quality studies were included after applying the inclusion and exclusion criteria. There were 14 studies for skin rejuvenation, 7 for acne scars, 6 for acne vulgaris, 5 each for striae and axillary hyperhidrosis, 2 for melasma, and 1 each for rosacea, cellulite, and androgenetic alopecia.

CONCLUSION

Radiofrequency microneedling is an effective intervention that can be used repeatedly and safely in combination with other treatment modalities and in individuals with darker skin phototypes. Radiofrequency microneedling-induced dermal remodeling and neocollagenesis are slow and progressive but continue to improve even 6 months after treatment.
