Injectable Platelet-Rich Fibrin and Microneedling—A Non-Surgical Approach for Gingival Augmentation: A Randomized Controlled Clinical Trial

Aim:

The present study aimed to assess the efficacy of combining microneedling (MN) and injectable platelet-rich fibrin (i-PRF) administration with i-PRF alone in augmenting the thickness of gingiva to manage thin periodontal phenotype.

Methodology:

The clinical trial involved 36 patients who were diagnosed with thin periodontal phenotype. They were randomized under two groups: MN + i-PRF versus i-PRF alone, carried out as a split-mouth trial. One quadrant was treated only with i-PRF delivery through the gingival sulcus, while the contralateral side was treated with MN and i-PRF in 3 sessions at 10-day intervals. The primary parameter measured was the thickness of the gingiva, at baseline and 3 months following therapy. Statistical analysis was performed using the Mann-Whitney U test. Wilcoxon’s signed ranking test for inter-group and intra-group analysis, respectively.

Results:

The study results showed a significantly greater increase in gingival thickness (GT) in sites where both MN and i-PRF injection was done, compared to i-PRF alone, with a p value of .04.

Conclusion:

Both treatment modalities showed improvement in GT, being a minimally invasive alternative for mucogingival surgery. Adjunctive MN was found to be more beneficial than i-PRF alone. However, further research should be carried out to address the drawbacks of the study and for a better understanding of this novel approach.

Prevention of Ageing-The Role of Micro-Needling in Neck and Cleavage Rejuvenation: A Narrative Review

Although interest in aesthetic medicine is growing, the focus is often placed outside of the facial area, namely on the skin of the neck and cleavage. Exposure to the sun and muscle movements cause the prompt development of wrinkles that may appear there, even before they show up on the face. We conducted a literature review devoted to micro-needling to identify its role in anti-ageing treatments and to determine the gaps in current knowledge. A search in Medline identified 52 publications for neck and face micro-needling. Micro-needling is an anti-ageing procedure that involves making micro-punctures in the skin to induce skin remodelling by stimulating the fibroblasts responsible for collagen and elastin production. It can be applied to the skin of the face, neck, and cleavage. Two to four weeks should be allowed between repeated procedures to achieve an optimal effect. The increase in collagen and elastin in the skin can reach 400% after 6 months, with an increase in the thickness of the stratum granulosum occurring for up to 1 year. In conclusion, micro-needling can be considered an effective and safe aesthetic medicine procedure which is conducted at low costs due to its low invasiveness, low number of adverse reactions, and short recovery time. Little evidence identified in the literature suggests that this procedure requires further research.

A Single-Center Trial to Evaluate the Efficacy and Tolerability of Four Microneedling Treatments on Fine Lines and Wrinkles of Facial and Neck Skin in Subjects With Fitzpatrick Skin Types I-IV: An Objective Assessment Using Noninvasive Devices and 0.33-mm Microbiopsies

BACKGROUND

Although ablative techniques are the standard of care for the treatment of fine lines and wrinkles, microneedling offers a minimally invasive alternative.

OBJECTIVES

The purpose of this study was to assess the efficacy of microneedling on facial and neck fine lines and wrinkles.

METHODS

Thirty-five subjects between 44 and 65 years old with Fitzpatrick skin types I to IV received 4 monthly microneedling treatments over the face and neck. Subjects returned 1 and 3 months posttreatment. At every visit, high-resolution ultrasonography and optical coherence tomography were performed, and transepidermal water loss and skin elasticity were measured. Microbiopsies (0.33 mm) were collected pretreatment, before the fourth treatment and 3 months posttreatment.

RESULTS

Thirty-two subjects (30 females, 2 males) completed all 7 visits. Facial dermal and epidermal density increased 101.86% and 19.28%, respectively, from baseline at 3 months posttreatment. Facial elasticity increased 28.2% from baseline at 3 months posttreatment. Facial attenuation coefficient increased 15.65% and 17.33% at 1 and 3 months posttreatment, respectively. At study completion, blood flow at a depth of 300 µm decreased 25.8% in the face and 42.3% in the neck. Relative collagen type III and elastin gene expression was statistically higher 3 months posttreatment. However, total elastin protein levels were unchanged from baseline values. Dermal muscle formation was observed in 58% of biopsies extracted 3 months posttreatment compared with 15.3% at baseline.

CONCLUSIONS

The results illustrate the effects of microneedling treatments. Noninvasive measurements and biopsy data showed changes in skin architecture and collagen/elastin gene expression, suggesting skin rejuvenation, with new extracellular matrix production and muscle formation.

Evaluation of tolerability and skin changes after application of topical antiaging products based on Sibanid SG®, plant stem cells and regenerative and biostimulating active ingredients

BACKGROUND

The oxidative stress, the UV radiations, the matrix metalloproteinases (MMPs) and the hyaluronidase enzyme play an extremly important role in skin aging processes, leading an increasing production of elastase, collagenase and hyaluronidase that brings to degradation of collagen, elastin and hyaluronic acid respectively. They are responsible to provide strength, elasticity and moisture to the skin. Innovative devices were developed based on the effective ingredients against hyaluronidase and MMP. The inhibition of the destructuring enzymes of the dermis is the main mechanism of action of Bioliftan treatment, and this process is mainly addressed to hyaluronidase and MMP inhibition. The aim of our study was to evaluate the efficacy, tolerability and skin changes induced by antiaging topical based on Sibanid SG®, plant stem cells and regenerative and biostimulating active ingredients. The products tested are Bioliftan Day cream and Bioliftan concentrate.

METHODS

All parameters were evaluated before the beginning of treatment (T0), and 60 (T1) days later. The evaluation of the effectiveness of the products was performed by clinical examination, photographic and instrumental documentation by corneometry, X-rite, elastometry, Moisture Meter EpiD, Confocal microscopy.

RESULTS

The products tested after 60 days have induced an increase of hydration of the external cutaneous layers (P<0.0001), skin hydration (P<0.0001), skin brightness (P<0.01), skin elasticity (P<0.0001). All results were statistically significant. All volunteers completed the study. No patients reported side-effects. All results were confirmed by confocal microscopy.

CONCLUSIONS

Our study evaluated efficacy, tolerability and skin changes after 60 days of Bioliftan day cream and Bioliftan serum concentrate application on the skin aged. Our study has shown an excellent skin tollerance of the products tested.
