The core requirements for aesthetic laser equipment are ease of operation, precise control, and safety. The introduction of touchscreens has primarily optimized the following functionalities:
1. Simplify the operating process and improve treatment efficiency
Traditional equipment issues: Physical buttons or knobs are used to adjust parameters (such as energy, pulse width, and frequency), which require multiple presses or rotations, making the process cumbersome and prone to errors, especially during emergency adjustments.
Touchscreen advantages:
Slide adjustment: Quickly adjust energy intensity (e.g., from 10 J/cm² to 20 J/cm²) via the touchscreen, which is more intuitive than a knob.
One-click mode switching: Pre-set different treatment modes (e.g., spot removal, skin rejuvenation, hair removal). Doctors simply click the corresponding icon instead of manually adjusting each parameter individually.
Reduced misoperation: The lock function prevents accidental touches during treatment, making it more reliable than physical buttons.
Actual case:
In hair removal devices, when doctors adjust the energy level by sliding the touchscreen, the current parameters are displayed in real-time on the screen, avoiding setting errors caused by unclear markings on traditional knobs.
2. Precise parameter control to enhance treatment efficacy
Limitations of traditional devices: Mechanical adjustments may introduce errors (e.g., energy drift due to knob wear), affecting treatment consistency.
Touchscreen optimizations:
Digital input: Directly input precise values (e.g., 12.5 J/cm²), avoiding the roughness of knob adjustments.
Real-time feedback: If energy levels are too high during treatment, the screen provides immediate alerts (e.g., color warnings or vibration feedback), allowing doctors to quickly adjust settings.
Regional parameter settings: When treating different areas (e.g., the T-zone and U-zone of the face), corresponding parameters can be stored and quickly recalled.
Actual case:
In fractional laser therapy, doctors fine-tune energy levels based on different skin areas (acne scar depth), and the touchscreen offers greater precision than physical buttons.
3. Enhanced human-machine interaction, optimized treatment experience
Limitations of traditional devices: Status is displayed via indicator lights or simple LCD screens, providing limited information.
Touchscreen improvements:
Graphical guidance: Treatment steps are visualized (e.g., “Prepare-Irradiate-Cool” process prompts), lowering the learning curve for new users.
Patient confirmation: Parameters are displayed for patient confirmation before treatment (e.g., “Energy: 15 J/cm²”), reducing communication errors.
Emergency stop: A large emergency stop button is easier to trigger than a physical button.
Actual case:
During intense pulsed light (IPL) treatment, if the patient feels discomfort, they can immediately click the “pause” button on the screen, which is faster than searching for a physical button.
4. Adapt to complex environments and improve durability
Traditional issues: Beauty clinics have corrosive substances such as alcohol and gel, which can damage physical buttons or cause them to stick.
Touchscreen solution:
Liquid splash resistance: Capacitive or infrared screens can be waterproofed (e.g., IP65 rating) to prevent malfunctions caused by liquid ingress.
Glove operation: Some devices support medical glove touch control (e.g., projected capacitive screens), eliminating the need to remove gloves.
Scratch resistance: Tempered glass panels are more wear-resistant than plastic buttons.
Actual case:
During laser hair removal, doctors may have coupling agent residue on their hands, but the touchscreen can still be operated normally, while physical buttons may malfunction due to stickiness.
5. The actual value of antibacterial functionality
Traditional touchscreen risks: When multiple people operate the device, the screen may spread bacteria (such as Staphylococcus aureus).
Antimicrobial Screen Improvements:
Reduced Disinfection Frequency: Silver ion coatings provide long-lasting antimicrobial protection, reducing cleaning frequency by over 75%.
Compatible with Strong Disinfectants: Antimicrobial glass (such as Corning Guardiant) withstands alcohol wipes without affecting touch sensitivity.
Real-World Example:
In beauty chains, the same device serves dozens of people daily. Antimicrobial screens reduce cross-infection risks and meet health regulatory requirements.
