An objective method to assess the improvements of skin texture roughness after botulinum toxin type a treatment of crow's feet

Abstract

Botulinum toxin type A treatment of crow's feet was able to improve STR. The Antera device and software are a valuable, objective, easy and reproducible method to assess the effects of the toxin.

The efficacy and safety of neubotulinumtoxinA for the treatment of forehead horizontal lines in Asians – A clinical, prospective, interventional, split‐face study

“…In addition to the efficacy of BoNT-A in treating forehead lines, it is noteworthy that a study by Cavallini et al 21 This study has notable limitations. Firstly, the study did not assess the duration required to return to baseline, as it did not encompass the intervals for returning to the severity of wrinkles before treatment (relapse rates).…”

A Randomized Split-Face Study of Photodynamic Therapy With St. John's Wort and Indole-3-Acetic Acid for the Treatment of Acne

“…The images were analyzed using a dedicated software with a small filter suitable for the analysis of the fine lines. 24,25 Texture-related parameters, such as average roughness (Ra), root-mean-squared roughness (Rq), and maximum peak to valley height of the profile in the assessment length (Rt), and wrinkle-related parameters, such as indentation index (negative vertical deviations of the skin surface) and maximum depth (maximum depth of the wrinkle selected), were quantitatively analyzed using triplicate measurements. 25 The degree of subjective satisfaction with the improvement of acne and antiaging effects was assessed using a visual analog scale that ranged from 0 (not satisfied) to 10 (most satisfied).…”

“…[21][22][23] In this study, an in vitro experiment was conducted to determine whether SJW extract produces ROS and suppresses the growth of S. aureus and C. acnes by the irradiation of visible light. 24 Then, a randomized, split-face study was performed to compare the efficacy and safety of SJW-PDT with that of IAA-PDT for the treatment of acne. Furthermore, the skin rejuvenating effects of SJW-PDT were investigated.…”

Quantitative evaluation of rejuvenation treatment of nasolabial fold wrinkles by regression model and 3D photography

“…By collecting the reflected light wave length of the skin surface in the 5.6 cm × 5.6 cm area, a 2D or 3D image of skin is constructed, and the parameters of skin color, wrinkle, texture, and pigmentation degree are accurately measured. 13,14 At present, 3D camera has been applied in some researches to evaluate the wrinkle parameters quantitatively, but there is no report on the relationship between nasolabial fold wrinkles and age. This study attempted to use 3D imaging technology to quantify the parameters of the static nasolabial fold wrinkles and establish the mathematical model between the wrinkles parameters and age, so as to provide the basis for quantitatively evaluating the effect of rejuvenation treatment.…”

“…Antera 3D camera is a portable camera with complex algorithm, which can emit multiple wavelengths of parallel light. By collecting the reflected light wave length of the skin surface in the 5.6 cm × 5.6 cm area, a 2D or 3D image of skin is constructed, and the parameters of skin color, wrinkle, texture, and pigmentation degree are accurately measured 13,14 . At present, 3D camera has been applied in some researches to evaluate the wrinkle parameters quantitatively, but there is no report on the relationship between nasolabial fold wrinkles and age.…”
