Acne scars — how to remove them and why creams are not enough

The acne is finally gone. What remains are the marks it left behind — and often it is those, not the acne itself, that bother you most in the mirror. Small depressions on the cheeks, uneven skin texture, shadows that make-up conceals only until the first photo in harsh light.

The good news: acne scars are today one of the best-described topics in aesthetic medicine. The bad news: "drugstore" methods will achieve little here — and it is worth understanding why.

Where acne depressions come from

Every deeper inflammation in a hair follicle destroys part of the collagen in the dermis. When the inflammation subsides, the skin patches the defect — but often "sparingly", with a tissue deficit. A depression forms in that spot: an atrophic scar.

This is an important distinction, because a simple rule applies here: the longer active acne lasts, the more scars have time to form. That is why treating acne is at the same time the most effective scar prevention — and squeezing lesions is the quickest way to multiply them.

Depressions or discoloration? These are two different problems

Before you choose a method, check what you are actually seeing in the mirror.

Post-acne discoloration — flat, red or brown marks — are not scars. They are a remnant of inflammation that often fades on its own, and stubborn marks respond to depigmentation therapy and laser treatments for discoloration.

Atrophic scars — depressions you can feel with a finger, visible in side lighting — are structural changes. They will not disappear on their own and require treatments that rebuild the skin from within.

A mix of both problems is of course common. In that case the doctor decides the order.

Among the depressions themselves there are three different kinds, and it is these that determine the choice of method. Ice-pick scars are narrow and very deep, like the mark left by a needle. Boxcar scars have a wider base and clearly outlined edges. Rolling scars are the widest and give the impression of undulating skin, because the base is tethered to the deeper layers. In the mirror this often looks like one problem, but the treatment plan for each type is different — and that is why the first appointment consists mainly of examining the skin in side lighting.

What really works on atrophic scars

The common denominator of effective methods is: controlled damage that forces the skin to rebuild collagen.

Fractional laser — the method with the best documented action, although the best results usually come from combining several techniques. The beam, divided into microcolumns, damages 15–20% of the skin's surface, leaving the rest untouched as a "scaffold" for regeneration. The skin responds by producing new collagen and gradually making the depressions shallower. Depending on the depth of the scars, a non-ablative or an ablative CO₂ fractional laser is used — the choice belongs to the doctor. It copes best with boxcar and rolling scars; with narrow ice-pick scars the laser on its own achieves noticeably less.

Fractional microneedling radiofrequency — microneedles deliver energy directly deep into the dermis, bypassing the epidermis. A good option when a shorter recovery matters.

Microneedling — mechanical stimulation of remodelling, usually for shallower, diffuse scars.

Regardless of the method, the same rule applies: the result is built by a series — usually 3–6 treatments a few weeks apart. The skin needs time to remodel, so results keep building for another 2–3 months after the last treatment.

What to avoid

• Aggressive home peels — they irritate, and they will not change the depth of a scar.
• Squeezing remaining lesions — every new inflammation is a risk of a new scar.
• Treatments during active acne — first calm the lesions, then work on the scars; otherwise the results will be lost.
• Sun exposure after treatments — freshly remodelling skin discolours easily, an SPF 50+ sunscreen is mandatory. The risk of discolouration is not the same with every method: a fractional CO₂ laser puts more strain on the skin than microneedle radiofrequency, which with a darker complexion can be an argument for choosing a different treatment.

When is the best time to start

The season matters: after laser treatments the skin requires sun protection, so a series is most convenient to run from autumn to early spring. Starting in September–October, by summer you have a full series behind you and time for the results to show.

How much it costs and what the first step looks like

Fractional laser treatments start from 600 zł per session. The first step is a consultation: the doctor assesses the type and depth of the scars, distinguishes them from discoloration and puts together a plan — the method, the number of treatments, the intervals.
