Androgenetic alopecia (AGA) is the most common form of hair loss in adults, which is generally progressive in the absence of treatment. As a head full of healthy hair adds to the cosmetic appeal of the individual, the consequences of AGA are predominantly psychological. Currently, topical minoxidil is the first-line treatment for AGA. Many adjuvant treatment modalities have been used synergistically with minoxidil. Microneedling is one among such adjuvant treatments, which works by various mechanisms to stimulate the dermal papillary cells that play a key role in hair growth.

Microneedling therapy is a widely used technique in dermatology. However, little is known about the underlying molecular effects of this therapy on extracellular matrix remodeling, wound healing, and inflammation. The aim of this study was to examine morphological and molecular changes caused by microneedling treatment in a standardized in vitro full-thickness 3D model of human skin.

Microneedling is a relatively safe therapeutic procedure used to treat many dermatological conditions, including acne vulgaris, alopecia, melasma and other pigmentary disorders, as well as to promote skin rejuvenation, rhytide reduction, and scar remodeling. Given its popularity among patients and increasing use in the clinic and at home, we aim to explain the adverse effects associated with microneedling procedures.

Microneedling is a very simple, safe, effective, and minimally invasive therapeutic technique. It was initially introduced for skin rejuvenation, however, now it is being used for a very wide range of indications including acne scar, acne, post-traumatic/burn scar, alopecia, skin rejuvenation, drug delivery, hyperhidrosis, stretch marks, and many more. Moreover, during the last 10 years, many new innovations have been made to the initial instrument, which was used for microneedling. This technique can be combined with other surgical techniques to provide better results. In particular, it is a very safe technique for dark skin types, where risk of postinflammatory pigmentation is very high with other techniques that damage the epidermis. In this review article, we are updating on the different instruments now available for this procedure, and its efficacy when performed alone or in combination with other techniques for various

Cryolipolysis is a nonsurgical body contouring procedure that involves cooling of fat cells to induce lipolysis while sparing surrounding structures. Plastic surgery practices are increasingly incorporating noninvasive aesthetic procedures (eg, cryolipolysis, fillers, radiofrequency, ultrasound) to offer their patients a wider range of aesthetic treatment options. Here, we report insights from 8 plastic surgeons with regard to cryolipolysis best practices from a clinical perspective and the impact of integrating this noninvasive body contouring procedure into a plastic surgery practice. The authors prefer cryolipolysis over liposuction for patients who are not amenable to surgery or those who desire to avoid downtime, also taking into consideration body mass index, skin laxity, comorbidities, and risk of contour irregularities. Patient counseling is critical for setting realistic expectations regarding outcomes and should focus on the efficacy of cryolipolysis, individual variability in results, potential side effects, time

This study aimed to evaluate color longevity after 2 years of whitening gel (6% hydrogen peroxide (HP), blue LED/infrared laser activation system) in comparison to a control 35% concentration in a split-mouth study and investigate the long-term effect on quality of life (QOL).Thirty-one patients were treated. Whitening using 6% or 35% HP gel was performed on half of the upper jaw in each patient. The color was measured at baseline and 1 week, 1 month, 1 and 2 years after treatment using the Easyshade Vita spectrophotometer and the Vita Bleached and Vita Classical Shade Guides organized by value. During 2 years of follow-up, color was evaluated before and after dental prophylaxis. Oral Health of Impact Profile (OHIP 14) and Psychosocial Impact Dental Aesthetics Questionnaire (PIDAQ) surveys measured QOL. Nineteen patients were evaluated at the 2-year follow-up. Significant differences in ΔE

Vital bleaching is one of the most requested cosmetic dental procedures asked by patients who seek a more pleasing smile. This procedure consists of carbamide or hydrogen peroxide gel applications that can be applied in-office or by the patient (at-home/overnight bleaching system). Some in-office treatments utilise whitening light with the objective of speeding up the whitening process. The objective of this article is to review and summarise the current literature with regard to the effect of light-activation sources on in-office tooth bleaching. A literature search was conducted using Medline, accessed via the National Library of Medicine Pub Med from 2003 to 2013 searching for articles relating to effectiveness of light activation sources on in-office tooth bleaching. This study found conflicting evidence on whether light truly improve tooth whitening. Other factors such as, type of stain, initial tooth colour and subject

Introduction: Photoepilation by lasers is a popular procedure in aesthetic dermatology for removing unwanted body and facial hair. The use of the most appropriate laser wavelength is crucial as it affects treatment depth and melanin absorption. The three commonly used hair removal lasers are of specific wavelengths: 755 nm, 810 nm, and 1064 nm, each preferred certain types of skin and hair characteristics. The current evaluation reports the safety and efficacy of unique blended modes 755/810 nm and 810/1064 nm diode lasers for hair removal. 

Tooth whitening has been the subject of extensive clinical trials research since the introduction of the first hydrogen-peroxide whitening strips in 2000. Availability of digital image analysis, an unambiguous and reproducible method for assessing color change, has contributed to global clinical research and product development on whitening strips. The research has included a series of global randomized controlled trials in distinct sites and cultures, involving 6-6.5% hydrogen peroxide whitening strips used for 7-21 days. These studies, conducted at research hospitals, dental schools, and private dental practice, demonstrated significant color improvement with whitening strips relative to baseline and/or various controls without serious adverse events. This integrated clinical trials research provides important evidence of long-term safety and effectiveness of tooth whitening with 6-6.5% hydrogen peroxide whitening strips.

Cryolipolysis treatment, or cold-induced destruction of adipocytes, provides a noninvasive option for localized subcutaneous fat reduction without damaging the overlying skin or adjacent structures. This case study examines the long-term visibility of fat layer reduction subsequent to cryolipolysis treatment, through longitudinal evaluation. Two male subjects were unilaterally treated on one flank. Baseline and postprocedure photographs (at 2 or 5 years) of the treated and contralateral untreated flanks display durable results despite natural fluctuations in body weight.
