Laser Acne and Acne Scar Treatment in Ankara, Turkey

Laser acne and acne scar treatment is a modern dermatological method applied to reduce active pimples and skin irregularities caused in the past. Laser energy targets bacteria under the skin, reducing inflammation and stimulating collagen production. In this way, the skin texture is renewed and a smoother appearance is achieved.

Fractional laser technology is frequently preferred to reduce the depth of acne scars and even out skin tone. This method initiates the skin’s self-repair process by creating controlled microscopic damage. With regular sessions, the skin texture becomes stronger, pores tighten, and the appearance of scars is significantly reduced.

Laser systems used in active acne treatment prevent the formation of new pimples by balancing sebum production. They also help reduce redness and inflammation in the skin. In this way, both existing acne is brought under control and the formation of future lesions is prevented.

The skin may become sensitive after the treatment period, so the use of sunscreen and appropriate moisturizing is of great importance. The number of sessions is planned individually according to the severity of the acne and scars. Dermatological evaluation is the basic step to achieve an effective and safe result.

What is laser technology and how does it work in acne treatment?

A laser is actually a highly focused and powerful beam of light. The success of this technology in acne treatment is based on an intelligent principle we call “Selective Photothermolysis.” We can simply explain this complex term as “selectively heating and destroying a specific target through light.”

The laser is like a “smart bomb” that focuses only on the source of the problem without damaging the surface of the skin. It does not touch the surrounding healthy tissue. It recognizes different “targets” under the skin (we call these chromophores) and focuses its energy only on them. In acne treatment, we have three main targets:

• The Bacteria Itself: The chemical trace left by the acne bacterium.
• Redness and Inflammation: The damaged blood vessels created by the acne.
• Damaged Tissue: To repair acne scars and pits.

The laser works by locking onto each of these targets and triggering the skin’s own repair process.

How does laser light destroy the bacteria that cause acne?

The bacterium called C. acnes (or by its former name P. acnes), which lives inside the pores and causes acne, produces a substance called “porphyrin” as part of its life cycle. These porphyrins are very sensitive to certain light wavelengths of the laser (especially blue and red light).

When laser light comes into contact with these porphyrins, it triggers a chemical reaction. This reaction leads to the formation of molecules (free oxygen radicals) that are toxic to the bacteria. In simple terms, laser light neutralizes the bacteria, without the need for antibiotics, by using the substance it produces itself. This is a way of reducing one of the most fundamental causes of acne, namely the bacterial load, without medication.

Is there laser treatment for the stubborn redness left behind by acne?

Yes, and it is one of the most effective methods in the treatment of post-acne marks.

A pimple does not only contain bacteria, it is also an area of inflammation. Your body increases blood flow to that area to fight the pimple. Even after this “battle” is over, damaged and enlarged capillaries remain behind. Even if the acne subsides, these vessels continue to remain as a stubborn “red mark” in that area.

This is where vascular lasers come into play. The target of these lasers is “oxyhemoglobin” in the blood. Especially IPL, PDL (Pulsed Dye Laser), and KTP lasers are very successful in this regard. These lasers pass through the surface of the skin and directly target those enlarged capillaries. By heating the vessel in a controlled manner, they cause it to shrink and close. The body then naturally clears away this nonfunctional vessel. As a result, the underlying cause of the redness disappears and the skin tone returns to normal. This is a wonderful solution especially for people whose faces always look red even though their acne has healed.

How long does it take to get results from laser treatment?

This is one of the most important issues in acne treatment: having the right expectations. Laser treatments are not a “magic wand”; they are a process and require patience.

There are some important points to keep in mind:

• A single session is rarely sufficient.
• Generally, 4 to 6 sessions are required.
• There must be weeks between sessions.
• Results appear over time, not instantly.

The most interesting finding is that clinical improvement generally peaks weeks, or even months, after the last treatment session. Why? Because the laser triggers the skin’s own repair and remodeling mechanisms. Shrinkage of the sebaceous gland, complete subsiding of inflammation, and recovery of the skin take time. Therefore, it is very important to trust the process.

Why do acne scars look different, and how does laser treatment work here?

After active acne is brought under control, we need to deal with the “damage” left behind. Acne scars occur as a result of acne inflammation damaging the deeper layers of the skin (the dermis) and disrupting the normal collagen structure there.

Not all scars are the same. There are three main types of depressed (atrophic) scars:

• Ice Pick
• Boxcar
• Rolling

Ice Pick scars are deep and narrow; Boxcar scars are sharp-edged depressions; Rolling scars give the skin a wavy appearance.

Successful scar treatment requires a strategy for these different scar types. This is where “Fractional Lasers” come into play. While traditional lasers resurface the entire skin, “fractional” lasers do something much smarter.

You can think of this method like an aeration process that opens microscopic thousands of “thermal columns” in the skin instead of resurfacing the entire skin. While the places touched by the laser shot are treated, the healthy tissue left in between is not touched at all. These “healthy islands” allow the treated damaged areas to heal very quickly. In this way, we trigger strong collagen production in the depths of the skin without the long recovery periods and risks brought by resurfacing the entire skin.

What is ablative fractional laser (CO2) treatment and what is the recovery process like?

“Ablative” means controlled vaporization of the uppermost layer of the skin (the epidermis), in other words, “resurfacing.” Fractional Carbon Dioxide (FCO2) and Erbium:YAG (Er:YAG) are the “heavy hitters” of this group.

The target of these lasers is the “water” molecules in our skin. The laser light instantly vaporizes the water in the microscopic column it touches on the skin and removes that tissue column.

This is perceived by the body as a “serious injury” and triggers a tremendous surge in collagen production. The body goes into “emergency mode” to repair these microscopic wounds. This new, healthy collagen grows from the bottom up and replaces the pitted scar tissue.

This is the most effective method for those with severe and deep scars such as deep ‘Ice Pick’ and ‘Boxcar’ scars. Clinical studies show that this treatment provides a significant improvement of 30% to 70% in the appearance of scars.

However, this power comes at a cost: noticeable redness, edema, and crusting lasting 5 to 7 days are expected after the treatment. This period may require staying away from social life to some extent and going through an intensive care process at home.

Who is non-ablative fractional laser treatment suitable for?

“Non-Ablative” means leaving the surface of the skin (the epidermis) intact, without resurfacing. These lasers (for example, wavelengths of 1410 nm or 1550 nm) pass through the surface of the skin without disturbing it and deliver their energy directly to the lower layer of the skin (the dermis).

Without burning the surface, they create controlled “heat pockets” under the skin. Although this thermal effect is not as aggressive as ablative lasers, it strongly stimulates collagen production (neocollagenesis) by heating the dermis.

The biggest advantage of this treatment is the recovery process (downtime). After treatment, generally only temporary redness lasting the first 24 hours is seen. Makeup can be applied the next day and normal life can be resumed.

It is a perfect alternative for patients who have mild to moderate scars (especially ‘Rolling’ scars) or, most importantly, who do not have the luxury of taking time off from work or social life for recovery. Results are achieved more slowly and with more sessions (generally 3–5 sessions).

Interestingly, although ablative lasers provide more “visible” clinical improvement, in some studies non-ablative lasers have been found to be higher in terms of “patient satisfaction.” This shows how important the effect of the recovery process on the patient’s quality of life is.

Why are combination methods more successful in acne scar treatment?

Since acne scars are complex, the best results are generally achieved not with a single method but by combining different technologies.

• Laser + PRP (Platelet-Rich Plasma): This is one of the most powerful combinations today. The microscopic channels opened in the skin by the fractional laser (especially FCO2) create a valuable “delivery route.” Immediately after the treatment, the PRP solution obtained from the patient’s own blood and filled with growth factors is applied to the skin. These growth factors directly seep into the deeper layers of the skin through the opened channels. PRP provides “extra support and the highest quality material” to the “restructuring” process initiated by the laser. This synergy both maximizes collagen production and accelerates the recovery process.
• Picosecond Lasers (For Dark Skin Types): This is a revolution especially for olive-skinned and dark-skinned patients. Traditional lasers work with heat, and this creates a risk of pigmentation (PIH) in darker skin. Picosecond lasers, on the other hand, deliver their energy not in nanoseconds but in picoseconds (one trillionth of a second). This incredibly short pulse duration does not allow heat to accumulate. Instead of heat, they create a “photoacoustic” shock wave. This shock wave triggers collagen production under the skin. Its greatest advantage is this: because it does not create heat damage on the surface, the risk of pigmentation (PIH) in dark-skinned patients is significantly lower.

Is it safe to have laser treatment while using systemic isotretinoin (Roaccutane, etc.)?

This has long been a discussion in dermatology and is one of the issues that confuses patients the most.

The traditional rule was that it was necessary to wait at least 6 months after the use of this medication before undergoing invasive procedures such as laser treatment. The reason was the concern that isotretinoin could delay wound healing and increase the risk of abnormal scarring (keloid).

However, current scientific data and systematic reviews are questioning this strict rule. Analyses have shown that in hundreds of patients who underwent non-ablative (non-resurfacing) or fractional laser treatment during or immediately after isotretinoin treatment, the risk of serious side effects was “very low or nonexistent.”

This gives dermatologists the flexibility to intervene earlier in some patients, taking into account the fact that scars heal better with early intervention. Of course, for aggressive, fully ablative lasers (which resurface the entire surface), the 6-month waiting rule is generally still valid. This decision must definitely be made individually for the patient by a dermatologist who knows the risks and benefits.

What should I expect after laser treatment?

Some temporary side effects after laser treatment are normal and expected. These are part of the healing process and show that the skin is renewing itself.

The most common temporary conditions are as follows:

• Mild redness
• Swelling (edema)
• A sunburn sensation
• Temporary stinging or warmth in the skin
• Crusting and peeling (especially after ablative lasers)
• Temporary pigmentation (PIH) (especially in dark-skinned individuals, if not protected from the sun)

All of these effects are temporary and can be managed with proper care.

Which care rules should I follow to accelerate healing after treatment?

The success of laser treatment depends not only on the device but also on the patient’s compliance with post-treatment care. These rules must be followed to the letter in order to prevent risks that could sabotage the healing process or cause permanent damage.

Especially sun protection is of vital importance to prevent pigmentation. The skin becomes extremely vulnerable to UV rays. Likewise, avoiding products that can irritate the skin and not interfering with the healing process (such as not picking crusts) prevents the risk of infection and permanent scarring.

There are some critical rules you must follow for success after treatment:

• Strict sun protection (at least 4–6 weeks)
• Use of high-SPF, broad-spectrum sunscreen
• Reapplication of sunscreen during the day
• Avoiding irritating products (retinol, acids, alcohol)
• Using only gentle, fragrance-free cleansers
• Using only reparative, non-comedogenic moisturizers
• Avoiding intense exercise, sauna, and steam (for the first few days)
• Not taking very hot showers
• Not scratching the skin
• Absolutely not picking off crusts

How does a dermatologist plan laser treatment for acne and scars?

Successful acne and scar treatment is not a rushed single-session intervention, but a carefully planned step-by-step strategy. This requires drawing a “road map.”

• Stage 1: Extinguishing the Fire (Active Acne Control)

The priority is always to stop the active inflammation. You cannot plant new grass on a burning field. At this stage, lasers such as KTP (532 nm) are used to reduce inflammation, decrease the bacterial load, and control sebum production.

• Stage 2: Repairing the Damage (Scar Revision)

After active acne is brought under control, a plan is made according to the type (morphology) of the scars left behind.

The general approach is as follows.

• Deep Pits and Severe Scars: For the highest structural improvement, a combination of Fractional Ablative Laser (FCO2) and PRP (Platelet-Rich Plasma) is preferred.
• Situations Requiring Minimal Recovery Time: Fractional Non-Ablative (non-resurfacing) lasers are a safe alternative for patients with mild to moderate scars or those who cannot take time off from work.
• Stubborn Red Marks: If the scar is not pitted but only a red mark, vascular lasers such as PDL (595 nm) are essential to target this vascular component.
• Dark Skin Tone and Pigmentation Risk: To minimize the risk of pigmentation, Fractional Picosecond 1064 nm laser stands out as the safest and most effective option.

Is there a single “best” method in acne and scar treatment?

No. The “best” method is not a single laser device but a personalized, multimodal treatment regimen.

The era of relying on a single laser system in acne scar treatment is over. Current evidence clearly shows that the highest-level clinical results are achieved with sophisticated protocols that combine tissue ablation (resurfacing), collagen induction (stimulation), vascular modulation (redness reduction), and biochemical signaling (PRP or vitamins).
