Pain in Dermatologic Procedures — How It Can Be Managed

Three-Line Summary

• Pain passes through four stages: it starts in the skin, goes through the spinal cord, and is completed in the brain. What matters is that a modulation stage sits in the middle. Pain is not a fixed value set by the size of the stimulus but a variable you can reach at several points.
• The same procedure feels different from person to person. Skin thickness and density, nerve distribution in the area, sleep the night before, anticipatory anxiety and predictability all genuinely feed into intensity. The intensity you read in a review is not your intensity.
• The goal is not to endure it but to manage it. Saying that it hurts is information the procedure needs for safety, and each stage — before, during and after — has its own tools. Starting with lower-burden options is a legitimate route too.

Why the Same Procedure Is Bearable for One Person and Hard for Another

There is one thing we confirm over and over in clinic. The same device, the same settings, the same area — and the responses still differ. One person says it was easier than expected; another finds the same spot genuinely hard. That gap is not a question of willpower. The conditions that build the pain are simply different.

Studies on subcutaneous injection group the factors that influence pain into four sets: needle characteristics (gauge, length, sharpness), solution characteristics (viscosity, pH, osmolality, volume), injection technique (speed, depth, site), and patient factors (age, sex, weight, anxiety). It stands out that one of the four sets belongs entirely to the person. However well the clinician adjusts, the conditions you bring form one axis of the pain.

Differences in Pain Threshold Are Real

The sentence we hear most often from people who are sensitive to pain is, “Everyone else copes — it must just be me.” It is not. Differences in pain threshold are not a matter of attitude; they come from physical and physiological conditions like these.

• Physical properties of the skin — the thicker and denser the dermis, the less room the same volume of product has to spread, so local pressure builds higher.
• Nerve distribution by area — even within one face, nerve fiber density differs considerably from zone to zone.
• Condition on the day — sleep loss has been reported to raise pain sensitivity by around 40 to 50 percent.
• Previous experience — a painful memory raises the tension you carry into the next procedure, and that tension feeds back into how the pain registers.

There is a further reason this matters: it means pain control has to be individualized as well. Putting anesthetic cream on everyone for thirty minutes and starting may not be enough for someone whose conditions run sensitive.

You Do Not Have to Take a Review's Intensity as Your Own

Look up reviews of a procedure and you will find opposite descriptions of the same thing. “Didn't hurt at all” sits right beside “never again,” under the same name. Both can be true, because the conditions we have just gone through differ.

Borrowing someone else's intensity works against you in both directions. Read only the painless reviews and walk in unprepared, and an unexpected sensation lands harder. Read only the painful ones, and you start out already tense. What you need is not someone else's intensity but a plan matched to your own conditions.

The Four Stages That Build Pain

Pain begins at the nociceptors in the skin. The body carries millions of them, reported at roughly 2,000 per square centimeter of skin. These receptors detect mechanical, thermal and chemical stimuli and send them up to the brain along nerves.

The fibers that carry the signal are not all one kind either. A-delta fibers carry sharp, well-localized pain quickly, while C fibers carry dull, lingering pain slowly. The sting you feel first when a needle goes in, followed by an ache that stays, is those two routes of different character working with a time lag.

From Stimulus to Sensation: Four Gates

• Stage 1, Transduction — mechanical, thermal and chemical stimuli reach the peripheral nerve endings. Mediators released from damaged cells, such as bradykinin, prostaglandins and histamine, activate and excite the receptors.
• Stage 2, Transmission — the first-order neuron sends what it gathered at the periphery into the spinal cord (the dorsal root ganglion and dorsal horn), and hands it on to the second-order neuron. A-delta and C fibers take fast pain and slow pain respectively.
• Stage 3, Modulation — inhibitory and excitatory circuits in the spinal cord and brain adjust the size of the pain signal. Gate control and endogenous opioids belong here.
• Stage 4, Perception — the sensory information reaches the thalamus and cerebral cortex, and only there is the sensory and emotional recognition of “this hurts” completed.

Of these four stages, the one to look at hardest is stage three. Pain is not delivered from skin to brain untouched; its size is adjusted on the way. The existence of a modulating circuit means there are ways to reach into that circuit. That is why methods that look as simple as cooling the skin or applying vibration genuinely lower pain.

And stage four is not something to pass over either. Pain is completed in the brain, not in the skin, and that recognition is emotional at the same time as it is sensory. Saying that your state of mind feeds into intensity does not mean it is all in your head — it means that pain perception is built this way to begin with.

Each Stage Has a Different Place to Intervene

Splitting it into four stages is useful in practice precisely because the available intervention differs at each one.

• Intervening at stage one — the place where the stimulus itself is reduced. Depth and energy, injection speed, the viscosity of the product, and needle choice all belong here.
• Intervening at stage two — the place where the route upward is blocked. Topical anesthesia, and a nerve block limited to zones where pain runs strong, work at this stage.
• Intervening at stage three — the place where the size of the signal is adjusted. Cooling and vibration, which lower what you feel without blocking pain directly, go in here.
• Intervening at stage four — the place where perception is completed. A full explanation and predictability, breathing, and drawing attention elsewhere all take part.

This is why pain control is approached by layering several methods rather than relying on one. A single method generally acts on a single stage, but combining methods that act on different stages lets each one cover the others' gaps.

How Anticipatory Anxiety and Unpredictability Feed Into Pain

You may remember that anxiety was on the list of patient factors. Tension activates the sympathetic nervous system, and in that state the same stimulus registers as larger. Lying on the table holding your breath with your shoulders braced is about the least favourable condition there is for taking on pain.

Not Knowing Hurts More

A large share of anxiety comes from unpredictability. If you do not know when it starts, how many passes there will be, or how long a sensation lasts, you spend the entire procedure on alert. Know what is coming next, on the other hand, and the body takes the same stimulus in a prepared state. That is why the explanation before a procedure is part of pain control rather than a matter of courtesy.

Predictability generally comes out of four things.

• What kind of sensation — knowing in advance whether it is a sharp sting, a heavy thudding heat, or a tightening pull
• Order and count — which area we start from, and how many passes it is divided into
• A stop signal — simply having the agreement that raising your hand stops things creates a sense of control
• Where it ends — being told how much is left and how long, as we go

There are parts you can prepare yourself. Sleeping well the night before comes first; sleep loss raising pain sensitivity is exactly as described above. The second is breathing. 5-5-5-5 breathing — in for five seconds, hold for five, out for five, rest for five — helps lower tension, and with injections we sometimes run the procedure to the rhythm of the breath itself.

One thing we want to be clear about. Saying that anticipatory anxiety amplifies pain does not in any way mean the pain is your fault. If anything it is the opposite. It means there is one more variable that can be reached, and a large share of that variable is the clinic's to build for you, through how it explains and how it proceeds.

The Character of the Pain Differs by Procedure

Reduce pain to a single line — it hurts, or it does not — and there is nothing to prepare. In practice the character of the pain differs from procedure to procedure. Where it lands, in what form, and how long it carries all differ, and knowing the character changes how you prepare for it.

Heat in the Deep Layers — A Heavy, Thudding Pain

High-intensity focused ultrasound such as Ulthera Prime concentrates ultrasound energy at a single point to create micro-coagulation points at 60 to 70 degrees Celsius under the skin, particularly at the fascial layer. In the process, heat-sensing TRPV1 channels are activated and neuropeptides such as substance P and CGRP are released. In short, it is heat-driven nociception.

The texture of the sensation also changes with depth. With the 4.5 mm tip aimed at the fascial layer, the fascia contracts and the pain is felt as heavy and deep; with the 3.0 mm tip, collagen denatures and a tightening sensation tends to come to the front. This is where the description “it feels like my bone is ringing” comes from. But this pain has one advantage on the predictability side: it is pain broken into shots, so it does not run continuously — each sensation passes briefly.

Heat at the Surface — A Stinging, Hot Sensation

Sequential radiofrequency such as Density, and microwave-based devices such as Onda, work by making ions inside the tissue oscillate so that heat is generated. So the pain arrives from a shallower place, in the form of stinging and heat. It is clearly different in character from pain that thuds in the deep layers.

With radiofrequency there is one point worth setting out. Removing the pain completely can actually work against you. These are procedures where output has to be adjusted while reading through sensation how much heat is reaching the tissue. It is better for enough to be delivered within a range you can tolerate, and the intensity has to vary from area to area. So in radiofrequency we do not block pain as firmly as in injection or ultrasound procedures; instead we ask where you are at, at intervals. Here pain is not something to remove but information to read.

Injections — Mechanical Pressure and Chemical Stimulus Overlapping

Injections that place a product inside the dermis, such as Rejuran, are a different pain again. The dermis is shallow, dense tissue, so injecting into it takes more pressure than the broad, deep subcutaneous fat compartment. Intradermal injection is reported to require around 65 percent more pressure than subcutaneous injection.

Viscosity adds to that. The more viscous the product, the more slowly it spreads, pooling in one place and pushing the surrounding tissue aside, and that pressure stimulates mechanoreceptors. There is also a reaction that comes from putting in something other than water: the inflammatory response driven by the PN component can be left behind as a stinging sensation after the procedure. The mechanical stimulus of pushing through a dense network of collagen fibers, diffusion that runs unevenly along pores and sebaceous structures, and pressure that persists longer in a thick dermis all overlap.

So it is felt more strongly in areas where the dermis is thick and pores are numerous, and where bone sits directly underneath so pressure cannot disperse. The anterior cheeks, the chin and around the mouth are the usual ones. Beyond the area, people whose skin type is itself thick and dense tend to feel it more strongly.

Short, Repeated Stimuli — Needle and Laser Devices

Needle radiofrequency such as Potenza layers the first two together. The mechanical stimulus of fine needles entering the skin arrives along with the radiofrequency heat delivered at the needle tips. So sting and heat are felt stacked on one another, and what you feel also shifts with the depth the needles go to.

Lasers that leave microscopic thermal points in a grid, such as fractional CO2, and vascular lasers such as V-Beam, are built so that a single stimulus ends quickly but repeats many times over. What drives the experience in this group is often the number of repetitions and the interval between them rather than the intensity of any one of them.

Short, repeated stimuli are in fact a good shape for building predictability. Know how many passes it is divided into and roughly how long one zone takes, and the same stimulus passes far more easily. Taking a short break partway through is entirely possible.

That the character of the pain differs means the response has to differ too. For deep thermal pain, adjusting depth and energy by area and adding to the anesthetic approach is the right fit. For surface thermal pain, matching intensity through communication fits better, and for injection pain the first moves are the viscosity of the product, needle choice, and adjusting injection speed and depth.

Some Zones of the Face Are More Sensitive

Sensation in the face is carried by the trigeminal nerve, and this nerve divides into three branches. From the top: V1 (the ophthalmic nerve) takes the forehead, the eyes and the upper part of the nose; V2 (the maxillary nerve) takes the mid-cheek, the nose and the upper lip; V3 (the mandibular nerve) takes the lower lip, the chin, the jawline and the area around the ear.

These three zones are not equally sensitive. An analysis of chronic facial pain reported that V2 and V3 accounted for more than 95 percent of all pain, and nerve fiber density in V3 reaches roughly twice that of V1. In figures, density is reported at around 84 Units/cm² for the lower lip, chin, jawline and around the ear (the V3 territory), 67 Units/cm² for the mid-cheek, nose and upper lip (V2), and 48 Units/cm² for the forehead, eyes and upper nose (V1).

That is why so many people feel lifting procedures most strongly as they pass along the jawline and under the chin. The forehead and around the eyes, by contrast, tend to pass relatively easily.

We describe this map not to tell you in advance where it will hurt and leave you dreading it. It is because knowing beforehand means that zone can be prepared for separately. Allowing more anesthetic time on that area, adding an anesthetic approach limited to that zone, applying cooling and vibration together as we pass through it. Where in the procedure the sensitive zone falls can be adjusted as well.

Injection procedures follow a somewhat different map, because the thickness and density of the skin and the distance to bone weigh more heavily than the nerve branches do. It differs by area within one person, and from person to person. So with injections we read the state of the skin, gauge the likely level of pain in advance, and then prepare by adjusting anesthetic time or adding methods.

One thing to add: zones where pain runs strong not infrequently overlap with zones that matter for the result. The jawline is one of them. That is why managing the pain and going through with it properly is the better route, rather than skipping the area because it hurts.

Managing It, Not Enduring It

Change the way you approach pain and the experience of the procedure itself changes. See it as a gate to be survived and all that is left is holding on for the whole procedure; see it as a condition that can be adjusted and several places open up where something can be done.

Pain Is Also Information Needed During the Procedure

Pain is, in origin, a defence mechanism that protects the body. A sensation that differs from what was expected — one point unusually sharp, an unusually strong ringing in the bone, heat that lingers — may be information that depth or energy needs adjusting. We can only adjust if you tell us.

This is also why sedation and sleep anesthesia are not our default at ABLE.

• Many procedures need real-time confirmation — unlike surgery, dermatologic procedures often have to be carried out while checking in a mirror, or watching the change as the work proceeds.
• Sensory feedback plays into safety — you have to be able to tell us about excess heat or unexpected pain right away for us to change course mid-procedure.
• You can follow the process with us — it is better for both sides if you have the procedure knowing which area is being treated, at what intensity, and over how many passes.

None of this means simply putting up with it, of course. It means that because there are plenty of control methods that work while you are conscious, we reach for those first.

“That One Stings a Bit” Is Better Said Than Held In

Hold pain in and several things happen in the body at once. Muscles tense, breathing gets shallow, the sympathetic nervous system ramps up further — and pain sensitivity rises as a result. Enduring does not reduce the pain.

Seen over a longer span there is a more important reason. Repeated pain experience can sensitize the nerves and raise what you feel at the next procedure. Which is why pain being well controlled at the first procedure often sets the tone for every session after it. Handling it well from the start works out in your favour.

When you do speak up, a number makes the adjustment more precise. Tell us where you are between 0 and 10 on a numeric rating scale, and where your tolerable line sits, and we can match the intensity within that range. Asking you partway through the procedure is for the same reason.

Before, During and After — A Map of What You Can Reach For

Pain control is not a matter of leaning on one method. Anesthetic cream acts on the nerve endings in the dermis, cooling and vibration on the modulating circuits in the spinal cord, and adjusting procedure parameters on the size of the stimulus itself. Because the points of action differ, the more you layer them, the fewer gaps are left. Set out by stage, it looks like this.

Before the Procedure

• Pre-emptive analgesia — taking a painkiller in advance is known to help reduce pain. It has to account for your current medications and any underlying conditions, so it is decided in consultation.
• Sleep — a good night's sleep beforehand, on its own, changes the conditions for pain sensitivity.
• A full explanation — what sensation comes in what order, when it ends, and what to do when you want to stop, all agreed in advance.
• Topical anesthesia — the effect varies with application time, area and site. We allow different times for different people and different procedures.
• Order and layout of areas — where in the procedure the sensitive zones fall is decided beforehand.

During the Procedure

• Cooling — cold packs, ice rollers and cooling devices slow nerve conduction, reducing pain and also helping settle swelling after the procedure. It looks simple, and it is often overlooked.
• Vibration — stimulating the large sensory fibers (A-beta) closes the gate in the spinal cord that the pain signal passes through. One study found the effect strongest when vibration was applied to the same segment.
• Regional nerve block — applied only to zones where pain runs strong; it can also help where fear of pain is substantial.
• Nitrous oxide inhalation sedation — lowers anxiety and the felt intensity of pain while consciousness is maintained; considered where it is needed.
• Adjusting procedure parameters — depth and energy, number of passes, injection speed, needle choice and the viscosity of the product all feed directly into pain. With deep thermal procedures in particular, working while confirming the layer on screen matters for both pain and safety.
• Breathing and conversation — running the procedure to the rhythm of the breath, or light conversation that draws attention elsewhere, genuinely helps.

After the Procedure

• Cold compresses — help settle residual heat and swelling.
• Guidance on recovery — knowing in advance which sensations are natural and for how long cuts out unnecessary anxiety.
• Adjustment for the next session — we note which areas were particularly hard this time and carry that into the next plan.

These tools are not substitutes for one another but complements. Which combination to use depends on the type of procedure, the area, and pain threshold. How to use the most basic of them, topical anesthetic cream, more efficiently, and how to layer it with the other methods, is taken up next in Getting More from Topical Anesthetic Cream — Multimodal Pain Control.

You Can Also Start With the Lower-Burden Options

If pain is the biggest barrier right now, changing the order is a route too. It is rarer than you might think for there to be only one path to the change you are aiming for, and in many cases there is no need to start with a procedure that carries a heavy pain burden.

• Synerjet (needle-free delivery) — delivers the product into the skin by pressure rather than by needle. An option worth considering where fear of the needle itself is substantial.
• Olewave (piezoelectric shockwave) — it does not work by creating micro-coagulation points, so the pain burden is on the lighter side, and it sits on the collagen-stimulation and calming side of things.
• Choosing within the same family — within the Rejuran family, Rejuran HB+, where hyaluronic acid is added to PN and viscosity is lower, carries less pain burden. The composition and the session plan differ, though, so it is decided together in consultation.
• Splitting the areas — instead of doing everything at once, sensitive zones can be carried over to the next session.

The goal, though, is not to pick out only the procedures that hurt least. The goal is to get to a state where you can have the procedure you need. Starting with a procedure that carries a lower pain burden, getting used to the experience of a procedure itself, working out along the way which approach suits you, and then moving on to what you need — that order is often the more realistic one.

To add one note: what is set out in this article describes general mechanisms and tendencies of pain, and does not apply identically to everyone. The studies cited include findings obtained under different conditions. Pain threshold and skin condition, underlying conditions and current medications, and previous experience of procedures all shift what you actually experience, so which methods to combine and how is decided after assessment in consultation.

From Consultation to Procedure

A board-certified dermatologist examines you directly to identify the layer where the cause sits, decides on the device and the parameters, and then the same dermatologist carries out the procedure. There is no structure here where a consultant recommends procedures.

The number of sessions, the intervals, when to maintain and the cost are all agreed before the first procedure.
