• Gentle microcurrent stimulation for comfortable scalp contact
• Rounded comb teeth + ergonomic design for a scalp-friendly experience
• Lightweight cordless structure for easy use at home, in the office, or while traveling
• Water-resistant design for convenient use after washing hair

Most users typically use it 3–5 times per week for maintenance, or daily in short sessions depending on scalp condition. It\’s designed to make daily scalp care simple, comfortable, and consistent.

Radio Frequency (RF) technology uses high-frequency electromagnetic waves to generate controlled heat within the dermal layer of the skin. This thermal effect causes immediate contraction of aged collagen fibers, resulting in a temporary tightening effect, while also stimulating fibroblasts to produce new collagen over time for improved skin firmness and elasticity.

The effectiveness of RF treatment depends on how energy is delivered into the skin. Different RF frequencies determine penetration depth: higher frequencies concentrate energy in more superficial layers, while lower frequencies reach deeper dermal structures. For this reason, advanced RF systems often use frequency modulation technology to achieve more controlled and layered heating rather than relying on a single fixed depth.

The effective temperature range for RF treatment is typically around 41–45°C. Below this range, the thermal stimulation is insufficient; above it, there is a risk of skin discomfort or damage. Therefore, temperature stability and energy control are key factors in RF device performance.

In home-use beauty devices, RF technology is widely used for non-invasive anti-aging treatments, supporting skin tightening, wrinkle reduction, and overall skin texture improvement through consistent and repeated use over time.

The core difference between ACE-TEC’s RF technology and standard RF beauty devices lies in the shift from single-point heating to layered, precision-controlled dermal heating, and from single RF functionality to a multi-technology integrated system designed for full-layer skin coverage.

Frequency Modulation System
The ACE-TEC FBD1 uses a frequency-modulated RF system ranging from 0.67 to 1.45MHz, enabling controlled energy delivery at different penetration depths through frequency switching:

• 0.67MHz (low frequency): penetrates deeper into the dermis, targeting deeper collagen structures to support skin firmness and address sagging and deeper wrinkles
• 1.45MHz (mid–high frequency): acts on the upper dermal layer, improving fine lines and overall skin texture

• Modulated RF: provides layered dermal heating to activate collagen remodeling across multiple skin depths
• EMS (10Hz / 100Hz alternating mode): stimulates facial muscle contractions to support lifting and contour definition. EMS operates simultaneously with RF, meaning muscle activation and thermal collagen contraction occur at the same time, creating a combined “support + lift” effect
• 630±20nm red light: works concurrently with RF and EMS to support skin recovery and improve overall skin condition and radiance

RF devices generate heat in the dermis layer to stimulate collagen regeneration, but the epidermis has a safe temperature threshold of around 43°C. Exceeding this level may cause skin damage, so temperature control is the core safety mechanism in RF devices.

A safe RF device typically relies on three levels of protection:

1. Real-time temperature monitoring (hardware level)
   NTC thermal sensors are embedded in the RF handpiece to continuously monitor skin surface temperature in real time.
2. Intelligent power control (system level)
   When temperature approaches the safety threshold, the system automatically reduces energy output, and further shuts down output if the limit is exceeded.
3. Multi-layer safety protection (redundancy level)
   Additional protections such as skin contact detection, automatic shut-off when removed from skin, and time-based safety control help prevent overheating in different usage scenarios.

ACE-TEC RF devices (such as the FBD1 RF beauty device) integrate real-time NTC monitoring and multi-level safety control systems to ensure stable energy output within the safe temperature range during use.

At ACE-TEC, quality is built into every stage of product development and manufacturing—not just at final inspection.

Our quality management system is certified to ISO 9001 and ISO 13485 and follows a structured quality control process covering the entire product lifecycle. This includes:

• Design quality planning: DFMEA and PFMEA are applied during product development to identify and reduce potential risks before production begins.
• Incoming Quality Control (IQC): Critical components such as PCBs, batteries, motors, and electronic parts are inspected before entering production.
• In-Process Quality Control (IPQC): Key manufacturing processes are monitored throughout production to ensure assembly consistency and process stability.
• Final Quality Control (FQC) & Outgoing Quality Control (OQC): Every finished product undergoes functional testing, appearance inspection, and safety verification before shipment.
• Reliability testing: Depending on the product, devices undergo aging tests, high- and low-temperature testing, drop tests, button life tests, waterproof testing, and other reliability evaluations to verify long-term performance.
• Full traceability: Production records and batch information are maintained throughout the manufacturing process, enabling traceability from raw materials to finished products.

By combining preventive quality planning, in-process control, reliability validation, and full traceability, we ensure consistent product quality from prototype to mass production.

At ACE-TEC, we ensure product reliability through a prevention-first approach — integrating quality planning and risk control from the design stage, rather than relying only on final product testing.

Our reliability assurance system is built on three key pillars:

1. Design Risk Prevention
   Before production begins, our engineering and quality teams apply DQA, DFMEA, and PFMEA methods to identify potential design and manufacturing risks early, helping prevent issues before they occur.
2. Reliability Validation & Testing
   Each product undergoes systematic validation, including functional verification, safety testing, aging tests, high and low temperature tests, drop tests, charging cycle tests, and other product-specific evaluations. Across different product categories, ACE-TEC conducts more than 57 reliability tests to simulate long-term usage conditions.
3. Manufacturing Validation & Process Control
   Before mass production, pilot production runs are performed to verify process stability and product consistency. Supported by our MES manufacturing system and in-house production capabilities, we ensure a smooth transition from prototype development to scalable production.

Through preventive design, rigorous validation, and controlled manufacturing, ACE-TEC helps global brands reduce product risks and launch reliable beauty devices with confidence.

At ACE-TEC, we manage product traceability through a digital manufacturing system integrated with MES and ERP, enabling transparent and controlled production from incoming materials to finished products.

Each production process is recorded through our MES system, with more than 2,000 process parameters collected and monitored daily. Every device is assigned a unique serial number, allowing us to trace its complete manufacturing history, including material batches, production records, inspection results, and key process data.

This device-level traceability allows our team to quickly identify the root cause of any quality deviation, accurately define affected batches, and implement targeted corrective actions when needed.

As an ISO 13485 certified manufacturer, our traceability system follows medical device quality management requirements, supporting two-way traceability from raw materials to finished products and from finished products back to source materials.

Beyond traceability, we continuously improve manufacturing quality through data analysis and CAPA (Corrective and Preventive Action) processes, using production data and quality feedback to optimize processes and prevent recurring issues.

Through digital manufacturing, complete traceability, and continuous improvement systems, ACE-TEC ensures stable quality control and long-term manufacturing reliability for global beauty brands.

Yes. Golden sample approval is a standard part of ACE-TEC\’s quality launch process to ensure consistency between approved samples and mass production.

Before mass production, we create a golden sample (master sample) as the production reference standard. The sample is reviewed and approved by both ACE-TEC and the brand partner, covering key requirements such as appearance, color, structure, functionality, and packaging.

Once approved, the golden sample becomes the quality benchmark for production. During the first production run, our quality team performs first article inspection (FAI) to verify that mass-produced units match the approved standard before full-scale production begins.

The golden sample is retained throughout the product lifecycle and used together with our in-process quality control (IPQC) system to maintain consistency across future production batches.

Through golden sample approval and controlled production processes, ACE-TEC helps brands ensure that the final products they receive match the quality standard they approved.
