When consulting about acne scars or deep pores, “Infini” and “CureJet” often come up together. Since both are classified as RF micro-needle treatments, they may seem similar at first glance, but the price list and downtime guidance make the differences quite clear.

To put it simply, the two procedures share the broad framework of “needle + radiofrequency,” but they differ in needle depth, energy delivery, and the types of scars they address. So instead of expecting that “one treatment will solve everything,” it’s better to choose according to the scar pattern and recovery schedule. It is also in this same context that acne scar treatment often combines methods such as microneedling and radiofrequency.

The Bigger Picture: RF Micro-needling

RF micro-needling is a procedure that uses fine needles to puncture the skin and deliver radiofrequency energy deep into the dermis. Unlike ablative lasers that remove the surface to stimulate fresh collagen formation, this treatment largely preserves the skin surface while applying thermal stimulation directly to the dermal layer to encourage new collagen production.

For that reason, the surface downtime is relatively short. On the day of treatment there is swelling, and by the next day you may see tiny pinpoint marks; within a week, the surface traces usually settle down. However, collagen remodeling taking place deep in the dermis appears gradually over 1 to 3 months.

RF micro-needle*: a device that punctures the dermis with fine needles and delivers radiofrequency energy. You may see it under various names such as Infini, Potenza, Secret RF, and CureJet.

Where Infini RF Is Strongest

Infini uses insulated fine needles, so RF is emitted only at the needle tip. Because the needle depth can be adjusted between 0.5 and 3.5 mm, it is especially effective for boxcar and icepick scars that need to reach the deeper dermis.

Since it leaves the surface relatively intact while building collagen in deeper areas, Infini’s advantages become clearer the deeper the scar is. That said, because it works strongly in deeper tissue, swelling and pinpoint marks on the day of treatment are a bit more noticeable than with CureJet, and a basic plan is 3 to 5 sessions at 4- to 6-week intervals.

Where CureJet Is Strongest

CureJet is also an RF micro-needle device, but by making fine adjustments to needle depth and output, it is often used for relatively shallow concerns such as pores, fine scars, and rough skin texture. The per-session cost burden is often lower, and because surface changes tend to appear more quickly, the total number of sessions is sometimes set shorter than with Infini.

However, it may not reach deep boxcar and icepick scars as strongly as Infini. So if deeper scars are mixed in, many people combine it with Infini or other tools (subcision, TCA CROSS) rather than relying on CureJet alone.

How Should You Decide?

A common way clinics sort cases is by “scar depth” and “recovery schedule.” If deep boxcar and icepick scars are common, Infini is usually the first candidate. If pores, rough texture, and shallow scars are the main concerns, CureJet tends to be less burdensome. If both types are mixed, it’s better not to aim for a single device alone but to plan two or three treatments together.

In terms of recovery schedule, Infini can be set at 4- to 6-week intervals, while CureJet can be scheduled every 3 to 4 weeks. If you fail to keep up with sun protection between treatments, PIH (post-inflammatory hyperpigmentation) can set in and blur the results, so the care between sessions can influence the outcome even more than the procedure itself.
