Acne Scar Treatment in Dublin: Why Most of It Doesn't Work

Almost everyone who sits down in my clinic and says “I want to do something about my acne scars” has already spent money on the problem. Usually a few hundred euro, sometimes a few thousand. Creams, oils, facials, a course of something at a salon. And the honest reason it did not work is not that they bought the wrong brand. It is that most of it was never capable of changing a scar in the first place.

Acne scarring is one of the few things in aesthetics where the gap between what is sold and what actually works is enormous. So this is the conversation I have with patients before we treat any of it — including the part where I tell some people that what is bothering them is not a scar at all, and that the best thing they can do is nothing.

First: is it actually a scar?

This sounds like a technicality. It is the single most expensive mistake people make with this problem, so it is worth ninety seconds.

After a spot heals, two quite different things can be left behind. The first is a mark — a flat patch of brown, red or purple where the inflammation was. The colour has changed but the surface has not. The second is a scar — a genuine dent, pit or ridge, where the skin lost collagen during the healing and never rebuilt it.

Marks fade. Scars do not. Post-inflammatory pigmentation typically settles over three to twelve months on its own, faster if you keep the sun off it and slower if you do not. Daily SPF does more for that problem than any treatment sold for it. A true scar will still be there in five years.

There is a simple test you can do at a mirror. Stand so the light rakes across your face from the side rather than hitting it head on, and look at yourself at an angle. Flat discolouration largely disappears under raking light. Texture becomes more obvious. If what bothers you vanishes in side light, you are most likely looking at a pigment problem — and a treatment aimed at collagen is the wrong tool and the wrong bill. It is a clue rather than a diagnosis, and plenty of people have some of both, which is what a proper look sorts out.

If you are still getting spots as well as looking at old ones, start with the active acne rather than the scarring: I have written separately about how we approach acne treatment in Dublin, and that is the right order to do this in.

The three kinds of scar, and why the distinction is not academic

When there is genuinely lost collagen, it does not all look the same, and it does not all respond the same way. Broadly there are three shapes.

Ice pick scars are narrow and deep — small punctures that look as though something fine was pushed into the skin. They are the ones people notice most in close-up light, and they are the most stubborn of the three, because the damage runs deeper than most resurfacing reaches.

Boxcar scars are wider, with fairly defined edges, like a shallow crater. Common on the cheeks and temples.

Rolling scars are the undulations — no clear edge, just a wave in the surface that shows up when the light moves. They are caused by fibrous tethers pulling the skin down from underneath, and they often respond the best of the three.

Most people have a mixture. That matters because it sets expectations honestly: a face with mostly rolling scarring can change a great deal, and a face with mostly deep ice pick scarring will improve but is unlikely to become smooth. Any clinic that quotes you the same outcome for both is not looking closely enough. I would rather tell you that at the consultation than after you have paid for four sessions.

What does not work, and why it is still sold

This is the part patients tell me nobody had said out loud to them before.

Scar oils and vitamin E. The commercial scar oils, rosehip, vitamin E, cocoa butter. These moisturise, and well-hydrated skin does look better. But a scar is a structural deficit several millimetres below the surface, and nothing spread on top of the skin reaches it or rebuilds it. They are pleasant, and they are not scar treatments.

Antiseptic aftercare creams. The zinc-based ones in most bathroom cabinets are good at what they are for — calming an angry spot while it is happening. They do nothing at all to an established scar.

Silicone gels and sheets. These do help raised scars, which is why they are used after surgery. Acne scarring on the face is usually the opposite problem — depressed, not raised — so for most people this is the right product for the wrong scar. Raised and keloid acne scarring does happen, more often on the jawline, chest and back, and that is the case where silicone earns its place.

Facials, including ones with our name on them. A HydraFacial is very good at congestion, blackheads and general skin condition. It is not a scar treatment and we do not sell it as one. If someone is offering you a course of facials for pitted scarring, that is a clinic solving its diary rather than your face.

Anything promising results in a fortnight. Collagen remodelling is slow biology. It takes months. A two-week promise is a claim about marketing, not about skin.

What actually changes a scar

Every treatment that genuinely improves acne scarring does the same fundamental thing: it injures the skin in a controlled, precise way, deep enough to reach where the collagen is missing, and lets the healing response rebuild it. That is the whole mechanism. The differences between devices are about how deep, how precisely, and how much downtime it costs you.

RF microneedling — the main tool

This is what we use for most acne scarring at Amara. Fine needles pass through the surface to a set depth, and radiofrequency energy is delivered from the needle tips into the deeper layer of the skin. The needles create the channels; the energy does the remodelling.

The reason it is the workhorse for scarring rather than plain microneedling is depth and control. Needling alone works at the surface and is genuinely useful for skin quality and fine texture. Adding energy at the tip lets us treat at the level where the collagen deficit actually sits, and vary that depth across the face — deeper on a scarred cheek, shallower near the eye. You can read more about how we use RF microneedling and what a session involves.

What it is like: numbing cream for about half an hour beforehand, then twenty to forty minutes of treatment. Most people find it uncomfortable rather than painful. Afterwards you are red and warm, similar to strong sunburn, for one to three days, and there can be some fine grid-pattern texture for a day or two. Most people are presentable for work on day two or three, and I would not book it the week of a wedding.

Peels, for the marks alongside the scars

Most people with scarring also have the pigment and general texture problem, and a peel is a reasonable, lower-commitment way to address that layer. We use BioRePeel at €159, and it is often run alongside a microneedling course rather than instead of it. It typically improves tone, clarity and superficial texture, though results vary. It will not fill a pitted scar, and you should be suspicious of anywhere that suggests it will.

Where it stops being an aesthetics question

Some scarring is better served by a dermatologist or a surgeon than by a device — particularly dense ice pick scarring, or scars that are tethered so firmly that they need to be released or excised individually before any resurfacing is worthwhile. And if your acne itself is moderate or severe, with deep tender lumps, cysts, or new scarring still forming, then the treatment that will help you most is medical treatment under a doctor, not a device. Amara is doctor-led, so that assessment can happen here, but I will say plainly when the answer is a prescription or a referral rather than a course with us.

How many sessions, honestly

This is the question that decides whether people are happy at the end, and it is the one most often fudged at the point of sale.

For acne scarring, plan on three to four RF microneedling sessions, spaced around six weeks apart. Some faces need more. One session will show you the skin looks better; it will not resolve scarring, and anyone selling a single session as a fix for pitted scars is overselling it.

The other half of the answer is timing. New collagen is not laid down the week after treatment — it builds over roughly three to six months. So the honest sequence is: four sessions across about four to five months, and then the result you actually judge it on is around nine months from starting. It is a slow project. Told that up front, people are pleased. Told nothing, the same result feels like a disappointment at week six.

Results vary from person to person, and depend heavily on the scar types you have, your skin, your age and whether the acne itself is settled.

What it costs in Dublin

Straight numbers, so you can plan rather than guess:

I would rather someone saw that number before booking a consultation than after. If it is not the right time, it is not the right time — the scars will be no worse in a year, and you will not have half-finished a course.

How we decide, in practice

A first appointment for scarring is mostly looking and asking, not treating. I want to know whether the acne is properly settled or still simmering, what you have already tried, which of the three scar shapes dominates, how your skin behaves after inflammation, and whether the thing bothering you in photographs is texture or colour — because as often as not, it is colour, and that changes the entire plan and the entire cost.

We use VISIA skin analysis to make that objective rather than a matter of opinion, and to have a fixed baseline to measure against later, since month-to-month memory of your own face is unreliable.

And sometimes the outcome of that appointment is that I tell you to spend the money on sunscreen and come back in six months. That is a real outcome, and a common one.

Common questions

Are acne scars permanent?

A true scar is, without treatment — it is lost collagen, and the body does not spontaneously replace it. The flat brown or red marks left after spots are not scars, and those usually do fade over three to twelve months.

How do you get rid of acne scars?

You cannot remove a scar in the way you remove a stain, but you can often soften one substantially by stimulating new collagen where it is missing — how much varies from person to person. In practice that means a course of a resurfacing treatment such as RF microneedling, sometimes with peels alongside for the pigment. Nothing applied topically does this.

Do scar oils or vitamin E work on acne scars?

Not on scars. They moisturise, and they can make skin look better in general, but a scar is a structural deficit under the surface and topical oils do not reach or rebuild it.

How many microneedling sessions do I need for acne scars?

Typically three to four, around six weeks apart, with the final result judged three to six months after the last session. Deeper or more extensive scarring can need more.

Can I treat scarring while I still get spots?

Generally not, and this is the most common reason a course underdelivers. Active inflammation is what creates scars in the first place, so resurfacing while breakouts continue means paying to repair damage you are still producing. Settle the acne first.

Is it safe on darker skin tones?

RF microneedling is generally better suited to richer skin tones than many ablative laser options, because the energy is delivered below the surface rather than being absorbed by pigment in it. It still requires care, appropriate settings and a proper assessment beforehand — which is exactly why we assess rather than treat at a first appointment.

Does it hurt?

With topical numbing, most people describe it as hot and uncomfortable rather than painful. The redness afterwards bothers people more than the session itself.

Where to start

If you are not certain whether you are looking at scars or marks, do the side-light test at a window before you book anything. If it disappears, you have a pigment problem and a far cheaper one. If the texture is still there when the light rakes across it, then it is worth a proper look and an honest conversation about which of the three shapes you have and what that realistically means.
