Explore our leading-edge professional devices engineered to deliver micro-thermal therapeutic actions for deep dermis tightening, skin lifting, and cellular rejuvenation.
Founded in 2019, Foshan Kelli Beauty Co., Ltd. has scaled rapidly into a distinguished professional manufacturer focusing on the R&D, sophisticated engineering, and international distribution of advanced medical-grade aesthetic equipment. Headquartered in the manufacturing powerhouse of Foshan, China, our company integrates multi-disciplinary research in biomedical engineering, radio frequency technology, and mechanical design to supply global distributors, med-spas, clinical chains, and private labels.
Our operational roadmap is optimized to offer end-to-end support for custom electronics, therapeutic software calibration, and aesthetic industrial design. Through systemic investments in engineering excellence and structural supply chain management, we export high-performing radiofrequency (RF), high-intensity focused ultrasound (HIFU), and transdermal electrical muscle stimulation (EMS) platforms to Europe, North America, South America, Southeast Asia, and the Middle East.
Modern commercial stakeholders face rigorous requirements for anti-aging equipment supply chains. In a market demanding high energy efficiency, clinical reproducibility, and safety, selecting a qualified RF device factory involves evaluating both mechanical stability and electrical engineering compatibility. Foshan Kelli Beauty solves these concerns by standardizing our operations according to macro-level business demands.
Every RF device we construct follows a rigorous design, validation, and testing procedure inside our modern, state-of-the-art facility. Our production line focuses on avoiding contaminants while maintaining precise mechanical alignments. Through rigorous semi-finished and finished testing stages, we verify the output frequency stability, current pathing, thermal cut-offs, and microcurrent parameters before shipping.
Radiofrequency skin tightening operates on the principle of high-frequency dielectric heating. When applied to the skin, electromagnetic waves generate an oscillating electrical field, causing charged ions and polar molecules in tissue to rotate rapidly. This friction generates localized thermal energy in the reticular dermis, heating collagen fibers to 55°C – 65°C.
This controlled thermal injury immediately disrupts hydrogen bonds, contracting collagen fibrils. Over subsequent weeks, fibroblasts undergo neocollagenesis, repairing and generating new Type I and III collagen networks. The key technical challenge is maintaining consistent energy delivery to target tissues while protecting the epidermis. Our hardware designs employ active impedance feedback, ensuring safe energy delivery regardless of variations in skin thickness or moisture levels.
| Aesthetic Technology | Primary Biophysical Mechanism | Target Anatomical Depth | Core B2B Commercial Applications |
|---|---|---|---|
| Monopolar / Bipolar RF | Ion-friction thermal heating to stimulate dermal remodeling. | Dermis (1.5mm - 3.0mm) | Wrinkle attenuation, subdermal tissue remodeling, double-chin reduction. |
| Fractional RF Microneedling | Insulated micro-needles deliver RF directly to deep dermal layers. | Deep Dermis & Fibroseptal network (up to 4.0mm) | Acne scar resolution, deep structural tightening, stretch marks treatment. |
| High-Intensity Focused Ultrasound (HIFU) | Highly focused sound waves trigger thermal coagulation points. | SMAS Layer & Deep Fascia (3.0mm - 4.5mm) | Non-surgical face lifting, cheek contouring, deep jawline definition. |
| Microcurrent / EMS | Micro-amperage current stimulates ATP production and myofibril activity. | Subdermal Musculature (SMAS interface) | Facial muscle toning, surface drainage, rapid contour enhancement. |
As regulatory environments tighten in key markets like Europe (with MDR 2017/745 transition protocols) and the United States (via FDA 510(k) clearances), aesthetic device factories must enforce absolute traceability. Foshan Kelli Beauty is committed to meeting these standards through comprehensive validation testing.
We utilize medical-grade materials, such as biocompatible polycarbonate-ABS alloys, for all skin-contact housings. Our RF circuitry is calibrated to prevent electromagnetic interference (EMI) issues, ensuring compliant integration into EU and US clinic systems. In addition, our manufacturing facilities adhere to ISO 13485:2016-aligned procedures, establishing clear lot traceability for all sub-components, from power transformers to micro-needling tips.
Answers to critical regulatory, engineering, and manufacturing questions for distributors and global procurement teams.
For standard factory colorways and bulk device shipments with custom silk-screened logos, our MOQ starts at 100 units. For comprehensive ODM projects, including custom plastic injection tooling and modified PCB firmware, MOQs generally start at 500 to 1,000 units depending on components.
Our premium RF devices are equipped with real-time contact sensors and intelligent proportional-integral-derivative (PID) controllers. When the handpiece detects skin surface temperature approaching 42°C - 43°C, the power output automatically shifts or limits itself to prevent thermal injury while ensuring the deeper tissues remain within the therapeutic range.
Yes. We design our beauty systems with universal switching power adapters (supporting 100V–240V at 50Hz/60Hz). We supply customized regional plugs (US, UK, EU, AU, ZA) to match localized commercial standards.
Every device undergoes a multi-phase testing protocol: initial component screening, post-soldering circuit testing, functional output calibration, a continuous 4-hour burn-in stress test, and a final cosmetic assessment before packaging.
Yes, our engineering team specializes in hybrid systems. We manufacture multi-modality tools combining EMS, LED phototherapy, fractional microneedling, and thermal RF to help brands maximize their return on investment.
