Abstract

This study aims to pinpoint the fundamental challenges encountered by a beauty clinic in Jakarta and develop an appropriate business strategy through qualitative research methods. Data were gathered via in-depth interviews with 15 participants, consisting of 10 active clients, 5 inactive clients, 3 therapists, and 1 operational manager, complemented by participatory field observations conducted over a three-month period. The findings revealed four primary issues: inconsistent service quality, weak brand identity and differentiation, inadequate digital marketing strategies, and the absence of a customer loyalty system. In response to these findings, a business plan was formulated encompassing service standardization, brand repositioning, enhanced digital marketing optimization, and the creation of customer retention programs. This research underscores the significance of employing qualitative approaches to comprehend consumer expectations and formulate experience-driven service business development strategies. The implications of this study provide practical guidance for beauty clinic managers in designing customer-centric business models and offer methodological contributions to qualitative research applications in service industry contexts.

Abstract

BACKGROUND: Oxidative stress plays a central role in skin aging by promoting reactive oxygen species–mediated collagen degradation, fibroblast senescence, and dermal thinning. Although radiofrequency microneedling (RFM) and polydioxanone (PDO) filler individually stimulate collagen remodeling, evidence regarding their combined efficacy in oxidative stress induced skin aging models remains limited. This study evaluated the effects of combined RFM and PDO filler therapy in a D-galactose–induced oxidative stress model of skin aging.METHODS: Thirty female Sprague-Dawley rats were randomly assigned into five groups (n=5): normal control (NC), aging control (AC), RFM monotherapy, PDO monotherapy, and combination therapy. Oxidative aging was induced by daily intraperitoneal injections of 50 mg/kg for 8 weeks, followed by a single post-induction treatment session. Skin samples were collected at 12 weeks post-treatment for histological assessment of dermal thickness (hematoxylin–eosin), collagen density (Masson’s trichrome), and fibroblast count.RESULTS: D-galactose significantly reduced dermal thickness, collagen density, and fibroblast count in AC compared with NC (p<0.001). All treatment groups showed significant improvement versus AC (p<0.05). Notably, only the combination therapy restored collagen density to a level comparable with normal skin (35.22 [28.74–40.35]% vs. 37.83 [33.11–40.69]%, p=0.124). The combination group also showed the highest increases in dermal thickness and fibroblast numbers among treatment groups.CONCLUSION: In this preclinical model, combined RFM and PDO filler therapy demonstrated enhanced restoration of dermal structure and collagen under oxidative stress–mediated skin aging, supporting its potential role in skin rejuvenation strategies.KEYWORDS: collagen density, dermal regeneration, D-galactose, oxidative stress, skin aging
