1. What exactly does a HIFU machine do? HIFU uses focused ultrasound energy to target deeper layers of the skin. Many professionals choose it because it supports natural-looking lifting and tightening without needles or downtime. It’s a dependable option for clients who want firmer contours but prefer non-invasive services. 2. What is the difference between 3D, 4D, 6D and 7D HIFU? Each “D level” refers to how the energy is delivered and how much control the technician has: 3D → good for general lifting 4D → faster coverage 6D → more detailed control 7D → the most versatile, with multiple cartridges and advanced precision Most medspas tend to choose 7D as their main device because it adapts easily to many face and body areas. 3. Are these HIFU machines suitable for both face and body? Yes. The collection includes cartridges for different depths, so you can work on delicate facial areas as well as body regions that need deeper contouring. 4. What cartridges do I need for lifting or firming? For most facial services, professionals use 1.5mm, 3.0mm and 4.5mm cartridges. For body sculpting, deeper options like 6mm, 8mm, 10mm, 13mm or 16mm are commonly selected. Your choice depends on your service menu and client needs. 5. How difficult is it to learn HIFU? Most technicians find HIFU easy to learn, especially with modern interfaces. We also provide guidance and support to help you set up the machine and get comfortable with the recommended protocols. 6. Do these HIFU machines require consumables? Only cartridges need replacement over time, and their lifespan is long enough to support busy treatment schedules. This makes HIFU one of the more cost-efficient technologies for spas. 7. Can I customize the machine with my own branding? Yes. We offer OEM/ODM options including your logo, custom interface, language settings, and even machine color. Many partners use this to build their own private-label beauty equipment line. 8. Are the machines CE certified? Yes. Each HIFU device in this collection meets CE safety and performance standards and is produced under strict quality control procedures. 9. Do you provide technical support? Absolutely. We offer guidance on setup, maintenance, and cartridge selection, along with responsive after-sales support for our global customers. 10. Do you ship worldwide? Yes. We ship to most regions and provide multiple shipping options, including DDP shipping for selected countries and fast express delivery for others.
