When purchasing gold radiofrequency microneedles, you can consider the instrument characteristics, treatment needs, safety and certification, price and cost-effectiveness. The following are the specific points:

Instrument characteristics
Number and diameter of needles: The number of needles affects the treatment area and efficiency. A small number is suitable for refined parts, and a large number covers a large area and has high efficiency; the diameter of the needle determines the size of the opening on the skin surface. Fine needles are more comfortable to treat, and thick needles have a strong pain but release more energy.

Insulation: Insulated needles only generate radiofrequency energy at the needle tip, which causes less damage to the epidermis and is more comfortable; non-insulated needles generate energy throughout the needle body, release more energy, and cover a wide depth, but it is difficult to repair later.

Treatment depth: The deeper the depth, the wider the range of treatment indications, and the improvement effect on wrinkles, skin sagging, aging and other problems is more obvious.

Radio frequency technology: The depth of monopolar radio frequency is deeper than bipolar radio frequency and 3D phased radio frequency, but 3D phased radio frequency is more comfortable.

Treatment needs
Anti-aging: You can choose insulated gold microneedles with relatively concentrated energy.

Improve enlarged pores, dull skin, acne or scars: You can choose non-insulated gold radiofrequency microneedles with a wider treatment range.

Treatment of thin skin areas such as the eye area and neck: You can choose instruments with negative pressure handles suitable for these areas.

Safety and certification
Certification: Choose instruments with authoritative certification, such as those with US FDA, China CFDA, European CE, etc., for more assured treatment.

Material: Gold is more stable in nature, and pigmentation or allergies rarely occur after treatment, such as the needle body of Bandao is made of gold.

Price and cost-effectiveness
Price range: The price of gold radiofrequency microneedles varies depending on many factors, mainly related to the size of the treatment area, the number of treatments, the level of medical institutions, regional differences, doctor experience, etc., and may range from 1,000 to 10,000 yuan.

Cost-effectiveness: Different brands and models of instruments have different prices. You can choose a cost-effective instrument according to your budget and needs.
