Acne scars are one of the most common skin concerns treated in medical aesthetic clinics. While today’s medical landscape offers a wide range of effective treatment options, many individuals struggle with one key question: which treatment is truly suitable for my skin?
The answer lies in understanding that acne scars differ in depth, texture, and structure, and each person’s skin heals in its own way. A treatment that works well for one individual may deliver very different results for another. This is why there is no single “best” solution — successful outcomes depend on carefully matching the treatment to both scar type and skin characteristics.
For a comprehensive overview, you may also find our complete acne scar treatment guide helpful. This article explains how acne scar treatments are selected based on different scar types and skin characteristics, so you can better understand your options. A personalised consultation with a qualified doctor remains essential to ensure treatments are safe, appropriate, and tailored to your skin’s needs.

Why Acne Scar Treatment Should Be Personalised
Acne scars develop when inflammation affects the deeper layers of the skin. During healing, the skin may produce collagen unevenly, which can lead to dents in the skin, raised scars, or dark marks that remain long after acne has cleared. Because everyone’s skin heals differently, acne scar treatment should always be tailored to the individual.
Many people try to manage acne scars using a single skincare device or topical product at home. While these may help with mild surface marks, they are often not effective for deeper or more complex scars. A personalised treatment plan allows doctors to match the right procedures to your scar type and skin profile, improving results and supporting safer recovery. Using an unsuitable treatment can lead to unwanted effects like skin irritation, prolonged redness, or post-inflammatory hyperpigmentation. In addition to scar type, personal skin characteristics also influence treatment results, including skin tone and sensitivity, oil production and acne tendency, pigmentation risk, collagen response and healing ability, and lifestyle factors such as tolerance for downtime.
Identify Your Acne Scar Type
Choosing the right acne scar treatment begins with understanding the type of scars present on your skin. It is also important to distinguish acne scars from post-inflammatory hyperpigmentation (PIH). PIH appears as dark spots left behind after acne heals, but it does not change the skin’s structure. True acne scars involve permanent changes in skin texture and require different treatment approaches.
1. Atrophic Scars (Depressed Scars)
Atrophic scars develop when the skin is unable to produce enough collagen during the healing process. This collagen loss causes certain areas of the skin to appear sunken or indented. They are the most common form of acne scarring treated in aesthetic clinics. There are three main types:
Ice Pick Scars
Ice pick scars are narrow, deep, and sharply defined, resembling small puncture holes in the skin. They extend into the deeper dermis, making them one of the most difficult scar types to treat. Surface-based treatments alone are usually insufficient, and doctors may recommend targeted or combination procedures.
Boxcar Scars
Boxcar scars appear as round or oval depressions with clearly defined edges. They can be shallow or deep and are typically wider than ice pick scars. Due to their shape, they often respond well to treatments that resurface the skin and stimulate collagen regeneration to improve texture.
Rolling Scars
Rolling scars create a wave-like or uneven appearance on the skin. They form when fibrous bands develop beneath the surface and pull the skin downward. These scars are often more widespread and usually require treatments that release the tethered tissue before improving skin smoothness.
2. Hypertrophic and Keloid Scars (Raised Scars)
Raised scars occur when the body produces too much collagen during wound healing. Instead of forming a flat surface, the scar tissue becomes thick and elevated. Hypertrophic scars remain within the boundary of the original acne lesion, while keloid scars extend beyond the original area and may continue to grow over time. These scars are less common on the face but may appear on the chest, shoulders, jawline, or back.
Understand Your Skin Type
Besides scar type, your skin type plays an important role in determining which acne scar treatments are most suitable and how well your skin will recover. Each skin type responds differently to energy-based devices, injectables, and resurfacing procedures.
- Oily and acne-prone skin produces excess sebum, which can clog pores and trigger new breakouts. Doctors often focus on stabilising acne first before moving on to scar-focused treatments.
- Dry or sensitive skin usually has a weaker protective barrier and is more prone to redness and prolonged inflammation. Doctors typically adjust treatment intensity or recommend gentler options.
- Normal skin is generally well-balanced and tends to respond well to most acne scar treatments with comfortable recovery.
- Combination skin includes both oily and dry areas, commonly an oilier T-zone with drier cheeks. Treatment plans often involve a customised mix of techniques tailored to each facial zone.
Acne Scar Treatment Options Based on Scar Type and Skin Type
After a professional consultation, your doctor will recommend treatments that align with your scar pattern and how your skin responds to procedures. Here are the main options:
CO₂ Fractional Laser Treatment
A medical-grade resurfacing laser that delivers thousands of microscopic beams into the skin to create controlled micro-injuries. These tiny treatment zones remove damaged skin cells while heating the deeper dermal layers, activating the body’s natural wound-healing response. Suitable for boxcar scars, rolling scars, mild to moderate atrophic scars, and uneven or rough skin texture. Works well for normal skin, oily skin (after acne is stabilised), and combination skin. Key benefits include improving depth and visibility of scars, smoothing coarse skin texture, refining enlarged pores, and enhancing overall skin clarity.
Microneedle Radiofrequency (RF)
A collagen-remodelling procedure combining mechanical microneedling with controlled radiofrequency heat energy. Ultra-fine insulated needles create precise microchannels while delivering thermal energy deep into the dermis. Suitable for rolling scars, boxcar scars, shallow ice pick scars, and mixed acne scar patterns across most skin types including mildly sensitive skin with adjusted settings. Key benefits include treating multiple scar types in one session, gradual skin tightening and firming, improved pore size and texture, and shorter downtime than ablative laser procedures.
TCA CROSS
A highly targeted chemical reconstruction method for deep, narrow scars. A high concentration of trichloroacetic acid (TCA) is carefully placed into individual scar pits, stimulating intense collagen regeneration and gradually pushing the depressed area upward. Suitable for deep ice pick scars, narrow deep boxcar scars, and scars too deep for lasers alone. Key benefits include effectiveness for very deep scar pits, gradual reduction in scar depth, and excellent results when combined with energy-based treatments.
Pico Fractional Laser
A precision laser delivering picosecond pulses in a fractional pattern. Instead of relying mainly on heat, it creates laser-induced optical breakdown within the dermis, stimulating collagen production and breaking down rigid scar structures. Suitable for shallow to moderate atrophic scars, mixed depressed scars, and early-stage scarring across most skin types. Key benefits include encouraging faster skin recovery, more precise energy delivery, and minimal disruption to surrounding tissue.
Subcision
A minor in-clinic procedure that treats the structural cause of certain depressed scars. A fine needle is inserted beneath the scar to carefully release fibrous bands that tether the skin downward. Once freed, the skin lifts naturally while the controlled healing response stimulates collagen formation. Suitable for rolling scars, tethered boxcar scars, and deep structural depressions. Key benefits include addressing the root cause of tethered scars and producing stronger outcomes when combined with lasers or RF.
