Background: The use of "skin boosters" comprised of hyaluronic acid (HA)‐based fillers to improve skin quality has gained popularity recently, especially in individuals interested in skin rejuvenation. Aim: This study aimed to evaluate the efficacy and safety of intradermal micropuncture injections of HA‐based gel filler combined with lidocaine (BYRYZN® SKINBOOSTER HA, ACROSS Co., Ltd., Gangwon‐do, Korea). Patients/Methods: A prospective, single‐arm, open‐label pilot study was conducted with study subjects who were aged between 30 and 60 years old and exhibited evidence of skin aging, such as wrinkles and loss of elasticity. They received three injections at 2‐week intervals and were followed up for a total of 12 weeks. Results: Twenty subjects with a mean age of 54.1 years were included. The mean Lemperle wrinkle scale demonstrated a 40% decrease from 2.60 ± 0.60 at baseline to 1.55 ± 0.51 at week 8. The improvement rate was maintained at about 33% until week 12. The average maximum height of the wrinkle (Rz, μm), average skin roughness (Ra, μm), skin elasticity (R2, AU), facial curved length (mm), skin pore size (mm2), skin hydration (AU), TEWL (g/hm2), and skin glossiness (gloss value, AU) exhibited statistically significant improvements over time compared with the baseline measurements. No serious adverse effects or persistent adverse effects were reported, except for a transient subcutaneous nodule in one subject. Conclusions: This study demonstrates that multiple microinjections of HA‐based gel filler for facial skin aging are safe and effective in improving facial skin quality. [ABSTRACT FROM AUTHOR]

Background: Baumann skin type questionnaire (BSTQ) has been widely used for evaluating skin types in dermatology. However, it requires excessive assessment time and lacks sufficient clinical validation for the Asian population. Aims: We aimed to establish optimized BSTQ based on dermatological assessment of the Asian population. Methods: This was a single‐center retrospective study, where the patient completed a modified BSTQ and a digital photography examination. The answers to four question groups for evaluating skin properties, including oily versus dry (O‐D), sensitive versus resistant (S‐R), pigmented versus non‐pigmented (P‐N), and wrinkled versus tight (W‐T) were compared with the measurements. Highly relevant questions are selected using two different strategies and used to determine the threshold level, which was compared with skin‐type measurement. Results: In O‐D, S‐R, P‐N, and W‐T, 3–5 out of 6, 2–6 out of 9, 3–6 out of 7, and 4–9 out of 11 questions were selected, respectively. As a result, skin type scores from two strategies and measurements showed similar Pearson correlation coefficient values compared to modified BSTQ (for O‐D and sebum, 0.236/0.266 vs. 0.232; for O‐D and porphyrin, 0.230/0.267 vs. 0.230; for S‐R and redness, 0.157/0.175 vs. 0.095; for S‐R and porphyrin, 0.061 vs. 0.051; for P‐N and melanin pigmentation, 0.156/0.208 vs. 0.150; for W‐T and wrinkle, 0.265/0.269 vs. 0.217). Conclusion: Two strategies for optimizing BSTQ are proposed and validated for Asian patients. Compared to the BSTQ, our methods show comparable performance with a significantly reduced number of questions. [ABSTRACT FROM AUTHOR]

Background: Angelica gigas Nakai is used as an herbal pharmaceutical material in Korea. Aims: To investigate the anti‐wrinkle effects of A. gigas Nakai root extracts (ARE) using mineral‐rich water in in vitro and clinical trials. Materials and methods: The cell viability of ARE was evaluated using a water‐soluble tetrazolium salt assay. After evaluating ARE's cytotoxicity, we used an enzyme‐linked immunosorbent assay kit to assess the effects of ARE on type I collagen in human dermal fibroblasts (HDFs). During a double‐blinded in vivo clinical study, participants were randomly assigned to use the sample and placebo formulations for the left and right sides of their face over an 8‐week period. We evaluated the anti‐wrinkle properties of the formulations using PRIMOS Lite and a global photodamage score. Results: A. gigas Nakai root extracts cytotoxicity was evaluated in HDFs. We demonstrate that ARE increased type I collagen production by 40% at 50 μg/ml as compared with the control. The use of an ARE lotion significantly reduced the presence of crow's feet wrinkles in comparison with the use of the placebo after 8 weeks. Additionally, use of the ARE lotion led to decreased photodamage scores, indicating anti‐wrinkle effects. Conclusion: The use of ARE with mineral‐rich water has anti‐wrinkle effects in in vitro and clinical trials. [ABSTRACT FROM AUTHOR]
