The main difference between semi-insulated and non-insulated radiofrequency (RF) microneedles is the amount of heat delivered to the skin.

 

Non-insulated needles heat the entire length of the needle, while semi-insulated needles only heat the tip. Some say non-insulated needles provide better results, but can be more painful and cause more downtime. Others say insulated needles are better for darker skin types.

Heat distribution:

Non-insulated needles heat the entire length of the needle, treating a larger area of skin. Semi-insulated needles only heat the tip, targeting the lower layers of the skin.

Results:

Some say non-insulated needles provide better results because they heat multiple layers of skin simultaneously.

Pain:

Non-insulated needles are said to be more painful than semi-insulated needles.

Downtime:

Non-insulated needles can cause more downtime than semi-insulated needles.Skin typeInsulated needles are said to be better for darker skin types because they protect the epidermis.
