It’s a bittersweet moment when you realize that you’re finally at the point where active acne is no longer constantly on your mind, but then the acne scars left behind show that your skin is not as quick to forget.

Are acne scars permanent? While having acne scars is nothing to be ashamed of—many people find that their scars add character to their face and make them more unique—if you are bothered by your acne scars and would like to reduce their appearance, there are many treatment options available for all types of scars.

In this article, we’re going to look at how acne scars form, whether or not acne scars are permanent, and we’ll provide you with a non-exhaustive list of available acne scars treatment options.

Acne Scars vs. Post-Inflammatory Hyperpigmentation

Acne scars and hyperpigmentation are two different skin conditions that are often confused with one another.

True acne scars are the result of damage to the skin caused by severe acne, usually cystic. They are permanent changes in the texture and appearance of our skin, which can include indentations, raised areas, and uneven texture. Acne scars occur when our skin’s healing process is disrupted, and our body produces too much or too little collagen in response to the damage. There are different types of acne scars, including ice pick scars, rolling scars, boxcar scars, and raised scars.

Post-inflammatory hyperpigmentation (PIH) on the other hand is a temporary condition that results in the darkening of the skin. PIH occurs when inflammation causes an overproduction of melanin, the pigment that gives color to our skin. This excess melanin accumulates in the affected area, resulting in the development of dark spots. PIH can occur in people of all skin types, but it is more common in individuals with darker skin tones.

The key difference between acne scars and hyperpigmentation is that acne scars are permanent changes in the skin’s texture, while hyperpigmentation temporarily affects the color of the skin. While both conditions can be treated, the approach will be different. Acne scars require more aggressive treatments, while PIH can often be treated with topical creams and serums.

Types of Acne Scarring

Unlike PIH, acne scars create a permanent change in the texture of our skin with either indented or raised scars. Before diving into acne scars treatment options, it’s important to understand the different types of acne scars. Each type of scar is formed differently, and as such they require a unique treatment approach.

Atrophic or Indented Acne Scars

Indented acne scars are the most common, and are usually located on our face. There are three main types of atrophic acne scars:

  1. Ice pick scars are deep and narrow, with a V-shaped indentation.
  2. Boxcar scars are broad and shallow, with steep sides.
  3. Rolling scars are broad and shallow, with a wave-like appearance.

Hypertrophic or Raised Acne Scars

Raised acne scars are seen more often where there was acne on the body, such as on the back and chest. They may cause irritation or itchiness.

Acne Scars Treatment

Are acne scars permanent? Unfortunately, acne scars are considered permanent and will not go away on their own.

In terms of how long it takes until acne scars fade, over time the hyperpigmentation of an acne scar will fade and the edges might soften, but they do require professional treatment in order to reduce their appearance. Treatment options depend on the type of scars (see above), and you will need to consult with a medical professional to decide on the course of treatment that will help your individual scarring.

Below is a non-exhaustive list of acne scars treatment options:

Chemical Peels

Chemical peels involve applying a solution to the skin that exfoliates the top layer of skin, which can help reduce the appearance of acne scars. There are different types of chemical peels available, including glycolic acid, salicylic acid, and trichloroacetic acid (TCA) peels.

For icepick scars, a procedure with TCA called “chemical reconstruction of skin scars” (TCA CROSS) is sometimes used where TCA is carefully applied to the base of the scar, which causes the skin to react and form a scab. As the scab heals and falls off, new skin forms in its place, which can help to fill in the depression caused by the scar. The TCA solution also stimulates collagen production, which can improve skin texture and tone.


Microneedling involves using a device with tiny needles to create small punctures in the skin, which triggers the body’s natural healing process and promotes the production of collagen. This can help reduce the appearance of acne scars.

In addition to traditional microneedling, there is also radiofrequency microneedling and platelet-rich plasma (PRP) microneedling. Radiofrequency microneedling combines microneedling with radiofrequency energy, which is a type of heat energy that can help to tighten and firm the skin. The device used for radiofrequency microneedling has needles that are insulated, so the energy is delivered directly to the deeper layers of the skin.

Microneedling with PRP involves combining microneedling with platelet-rich plasma (PRP), which is a concentration of growth factors derived from the patient’s own blood. The PRP is applied to the skin during or after the microneedling procedure, where it can help to promote healing and stimulate collagen production.

Laser Therapy

Laser therapy uses high-energy light to target the skin’s layers, which can help promote collagen production and reduce the appearance of acne scars. Your dermatologist will determine the best type of laser treatment for your acne scars which will depend on the type and severity of your scars, as well as your individual skin type and concerns.

There are different types of laser therapy available, including:

  • Fractional laser resurfacing: Uses a laser to create tiny columns of heat within the skin, which stimulates the body’s natural healing process and promotes the production of collagen and elastin.
  • Non-ablative laser resurfacing: Heats the dermis, or the deeper layer of the skin, without damaging the surface layer.
  • Ablative laser resurfacing: Removes the top layer of skin, which can help to reduce the appearance of shallow acne scars.
  • Pulsed dye laser: Targets the blood vessels beneath the skin’s surface, which can help to reduce the redness and discoloration associated with some types of acne scars.


Dermabrasion is a skin resurfacing procedure that can be used to treat acne scars. During dermabrasion, a dermatologist or plastic surgeon will use a specialized instrument to remove the top layers of skin in a controlled manner. The treated skin should grow back smoother, which can help to improve the appearance of acne scars.

Dermal Fillers

Dermal fillers are injections of hyaluronic acid or other substances that can help fill in the depressions of some acne scars, giving the skin a smoother appearance. Dermal fillers can be a relatively quick and non-invasive way to improve the appearance of acne scars, and the effects can last for up to a year depending on the type of filler used.


Subcision is a minimally invasive surgical technique that can be used to treat certain types of acne scars, particularly those that are tethered or anchored to the deeper layers of skin. Subcision involves using a needle under the skin to break up the fibrous tissue that is pulling the skin down and creating the depression. This can help release the tension and improve the appearance of the skin.

Punch Excision

Punch excision involves surgically removing the scar and suturing the skin together. After the procedure, the wound will heal and gradually fill in with new, healthy skin tissue. Over time, the appearance of the scar will become less noticeable. This is often used for deep acne scars, such as cystic acne scars, that cannot be treated with other methods.

Steroid Injection

For raised acne scars, which usually occur on the body, a small amount of corticosteroid medication can be injected by a doctor directly into the scar tissue. The steroid can help reduce inflammation and soften the collagen fibers in the scar. Over time, the combination of reduced inflammation and softened scar tissue can help the raised scar to flatten and become less noticeable.

At Home Acne Scars Treatment

While effective treatments to reduce the appearance of acne scars should all be done by a medical professional, there are some things you can do at home to work on your scars. The most important thing is to continue your acne treatment to ensure that you prevent any new scars from appearing. Use gentle products to protect your skin barrier and if you do get a pimple, try to keep from picking or popping it, as that will increase the chance of scarring. Instead, use a hydrocolloid pimple patch, which will create a clean and moist environment for the pimple to heal.

While it will not fix the texture of acne scars, broad spectrum sunscreen is important to protect your skin and fade any discoloration that might make the scars more prominent. Long term use of sunscreen will also protect the collagen in your skin from degradation which may make scars more visible.

Using a retinoid is unlikely to have an effect on severe scarring, however it can help even out your skin tone by promoting cell turnover and stimulating collagen production, which can make scarring less noticeable. Like sunscreen use, retinoids can help fade any hyperpigmentation on the scars which can make the texture less apparent. Retinoids are also helpful to thwart any new acne from cropping up which can help prevent more acne scarring over the long term. Retinoids are available over the counter in the form of adapalene and retinol. Prescription retinoids like tretinoin (Retin-A) and tazarotene (Tazorac) are stronger options that are available from your doctor.

If you are bothered by your acne scars, the unsolicited farewell gift of all forms of acne (including hormonal acne), there are fortunately many effective acne scars treatment options available. If you haven’t already, consult with a dermatologist to determine the best course of action for your individual needs.

If the cost of professional treatment for acne scarring is currently out of reach for you (unfortunately it is not usually covered by health insurance), don’t waste your money on advertised topical treatments that will not address the texture issues of acne scars—instead save your money to eventually be treated by a medical provider that you trust. In the meantime, make sure to keep up your acne treatment to prevent further scarring, use sunscreen every day to protect your skin, and consider a retinoid to help even out your skin tone and soften the appearance of scars.
