Acne scarring
Acne scarring is a collagen problem, not a pigment problem, and the two get confused constantly. The brown or red marks left behind after a breakout are post-inflammatory discoloration and they fade on their own over months. True scars are textural — the skin surface itself is depressed or tethered — and those do not fade, ever, without something that remodels collagen. Working out which one you have is the first thing we do, and it changes everything that follows.
Why this happens
When an inflamed lesion ruptures below the surface, the immune response that clears it also digests collagen in the surrounding dermis. What is left when the inflammation resolves is a small deficit of tissue. The skin above it drops into the gap, and that dip is the scar.
Scars are not all one shape, and the shape decides the treatment. Rolling scars are broad, shallow undulations tethered from below by fibrous bands. Boxcar scars have defined edges and a flat floor, like a small crater. Ice-pick scars are narrow and deep, sometimes deeper than they are wide, and they reach further down than most resurfacing does.
Post-inflammatory marks are a completely different mechanism. Brown ones are pigment deposited during the inflammation; red or purple ones are dilated vessels that have not yet settled. Both are flat. Both resolve over roughly six to eighteen months without any intervention at all, faster with sun protection. Neither is a scar, and treating them as one means paying for remodeling that was never needed.
The reliable test is light rather than color. Hold a light source to one side of the face and look at the shadows. Texture casts a shadow; pigment does not. It is the same test we do at the consultation, with better lighting.
What actually helps
Each of these does something specific about the mechanism above. The sentence under each one is what it does for this, which is not the same as what its own page says it does in general.
- Dermal filler
Used in small amounts under a distensible rolling scar to lift the floor toward the surface, as an adjunct to remodeling rather than instead of it.
- Microneedling
The workhorse for shallow rolling scars — repeated controlled injury builds new collagen into the deficit over a course of three to six.
- Radiofrequency microneedling
Adds heat at depth, which reaches tethering and deeper boxcar floors that needles alone pass straight through.
- Laser resurfacing
The most effective option for defined boxcar edges, because softening the rim is what makes a crater stop reading as one.
What won’t work
- Anything, on a mark that is flat. Flat brown or red marks fade on their own. Paying for a course of resurfacing to treat something that was going to resolve by itself is the most common waste of money in this category, and it happens because nobody separated the two first.
- Skincare, on a true textural scar. Actives improve pigment, tone and surface quality genuinely and measurably. A collagen deficit two millimeters below the surface is not a surface problem.
- One session of anything. Scar remodeling happens across a course and then continues for months after the last appointment. A person who has one treatment and assesses the result three weeks later has not seen the result.
- Aggressive treatment of ice-pick scars with a device that resurfaces broadly. They are narrow and deep, general resurfacing does not reach the base, and the usual outcome is improved surrounding skin around an unchanged pit.
Where we’d start, and why
- 1We photograph in raking light — a light source off to one side — because that is the only way to see the true extent of texture. Almost everyone is surprised by this photograph, in both directions.
- 2Then we sort what we are seeing into pigment, redness and texture, and we say out loud what proportion of your concern is each. If most of it turns out to be pigment and redness, that is good news and a much cheaper plan.
- 3For genuine texture, a course of microneedling is usually the first commitment — three sessions, four to six weeks apart, assessed at three months rather than at three weeks. Of everything on our menu it improves the most per day of recovery, and it establishes how your skin remodels.
- 4Radiofrequency microneedling or resurfacing comes after that, for what the first course did not reach. Starting with the heaviest treatment is how people end up with more downtime than the result justified.
What would make us decline
These are the answers we actually give in the room, and they are the reason the practice is called what it is called.
- You still have active breakouts. Treating scars while new lesions are forming means creating new ones behind the treatment, and we will ask you to get the acne settled first even though that means you leave without booking anything.
- You are expecting the texture to be gone. Scar treatment improves scars, often substantially, and it does not return the surface to what it was. If that gap is unacceptable — which is a reasonable position — we would rather establish it at the consultation than at the end of a course.
- Your scarring is predominantly ice-pick and you want it treated with a series of microneedling. It will not reach, we will say so, and we will explain what kind of practice does the procedures that address that shape.
- You have a history of keloid or hypertrophic scarring. Controlled injury is the mechanism of every treatment on this list, and in that context the risk of making things worse is real enough that we do not take it.
What this is not
Raised, thickened or spreading scars are keloid and hypertrophic scarring, which is a different biology entirely and is treated medically. Any scar that is growing, painful, itching persistently or changing color is a dermatology referral rather than an aesthetic plan, and so is any scarring accompanied by ongoing severe acne.
Questions about acne scarring
How do I tell a scar from a mark at home?
Take a photograph in side light — a window to one side of you, or a lamp held off to the side, rather than overhead or straight on. Anything that still shows up as a dip or a shadow is texture. Anything that disappears in side light and is only visible as color is pigment, and pigment fades.
How long do the flat marks take to fade on their own?
Usually six to eighteen months, faster on lighter marks and slower on deeper ones. Daily broad-spectrum sun protection genuinely speeds it up, because ultraviolet exposure keeps re-stimulating the pigment that is trying to clear.
How much improvement is realistic from a course?
For shallow rolling scars, a meaningful and visible improvement over three to six sessions, continuing for several months after the last one. For deeper and more defined scars, less, and often in combination with something else. We would rather quote a range than a figure, and we will not quote a percentage at all.
When is this something I should see a dermatologist about instead?
If your acne is still active or severe, if any scar is raised rather than depressed, if a scar is growing or symptomatic, or if you are considering isotretinoin. All of those belong with a physician before anything aesthetic is booked.
Does the improvement last?
New collagen laid down during remodeling behaves like the rest of your dermis and ages with it. The scar does not come back, though the face around it keeps aging, so a result reviewed at five years looks different from one reviewed at six months for reasons that have nothing to do with the treatment.
