Nearly every device in this family sets an energy level and a time, delivers it, and relies on the provider's judgment about what that did inside the skin. Skin resistance varies, so the same setting produces different heating in different places.
Profound worked the other way round. Each pair of needles carried a temperature sensor. The provider set a target temperature and a duration — around 67 degrees Celsius for a few seconds was a typical dermal setting — and the device adjusted its output continuously to hold that temperature at the needle. Instead of a dose of energy, you got a dose of heat.
That matters because the collagen response to heat is temperature-dependent in a fairly narrow band. Too cool and little happens; too hot and you cause damage rather than remodeling. Holding tissue in the right band for several seconds produces a stronger and more predictable response than a brief hot pulse.
The trade-off was that this is a much bigger treatment. Needles were inserted at a shallow angle and left in place for seconds rather than stamped in and out, spaced three millimeters apart with no overlap. It required injected local anesthetic — often nerve blocks — took an hour or more, and left real swelling and bruising.
Two handpieces existed. The 25-degree dermal handpiece, with five independent electrode pairs across a 14-millimeter head, treated the deep dermis for wrinkles and laxity. The 75-degree SubQ handpiece, with seven pairs across 20 millimeters, went into the fat layer and was used for cellulite.
The clearance language is worth reading, because it is unusually specific for this category. The dermal handpiece is described as being for percutaneous treatment of facial wrinkles; the SubQ handpiece for improving the appearance of cellulite, with the cellulite indication supported by long-term data in Fitzpatrick skin types I to III only. Most competitor devices are simply cleared for electrocoagulation and hemostasis, which says nothing about wrinkles at all.
Confirm which device you are actually being booked for — the original Profound or Profound Matrix. They are not the same treatment and should not be priced as if they were.
Ask how many Profound treatments the provider has performed and when they last did one. Discontinued devices tend to be used less often, and this one rewards practice.
Arrange a week clear of work and social commitments. This is not negotiable in the way it is for lighter devices.
Tell your provider about implanted electrical devices, blood thinners, any anesthetic reactions and any tendency to scar thickly.
Stop retinoids and acids about a week beforehand, and stop blood-thinning supplements if your provider advises it.
Arrive with clean skin, having eaten. Local anesthetic is injected and the treatment takes an hour or more.
Arrange a ride home. You will be swollen and numb.
Have ice packs, a spare pillow for sleeping propped up, and paracetamol at home before you go.
The treatment area is marked, usually with you sitting upright.
Local anesthetic is injected, often as nerve blocks plus infiltration along the treatment area. This part takes time and is the least comfortable stage.
The handpiece is placed on the skin and the needles are inserted at an angle. Unlike a stamping device, they stay in for several seconds while the system holds the tissue at the target temperature, then withdraw.
The provider repositions about three millimeters along and repeats, working across the area without overlapping.
With adequate anesthetic, most people feel pressure and warmth rather than pain. Without it, this would not be tolerable.
A lower face typically takes an hour to ninety minutes of treatment on top of the anesthetic.
You leave visibly swollen, often with the beginnings of bruising, and numb for several more hours.
Sleep propped up for the first few nights. No retinoids, acids or exfoliation for about ten days. Sunscreen daily.
None, and nothing close. This is a treatment performed under injected local anesthetic, with needles held inside the dermis for seconds at a controlled temperature. It is a medical procedure.
Home radiofrequency wands warm the skin surface. Home microneedling rollers do not deliver heat at all. Neither belongs in the same conversation.
If you want the effect and the device is not available to you, the honest options are a full course on another RF microneedling platform, which will do less per session but is widely available, or a surgical consultation if what you actually have is sagging rather than laxity. Comparing a $4,000 Profound treatment against a $4,000 course elsewhere is a fair comparison to make out loud.
