Living with acne can be difficult but, for many, the problems continue after the papules and pustules have cleared up. Acne can leave skin marked and scarred and, if someone has experienced severe acne, the subsequent scarring can be equally severe and distressing.

Thankfully, there are several options available for tackling these scars, but the best treatment is undoubtedly prevention - i.e. not getting the scars in the first place. If you are suffering from acute acne, then we recommend you consult a dermatologist as soon as possible. He or she will be able to recommend a treatment that can alleviate your acne so that scar formation can largely be avoided. 

You can find out which symptoms should prompt you to see a doctor and what he or she will then do here.

What causes acne scars?

Undoubtedly the most noticeable and most severe consequence of acne is scarring, but acne can leave other marks behind such as pimple marks caused by post-inflammatory hyperpigmentation (PIH). You can find out more about how to reduce and remove these in acne and hyperpigmentation.

Try to resist the temptation to fiddle with blackheads, whiteheads and other blemishes − either with your fingers or with other implements.

It’s when you squeeze blemishes too hard (especially those that have not yet fully formed) that you can damage the fine veins, glands and tissues that surround them.

This can make the symptoms of acne worse and increase the risk of scarring. Scars form when the outermost layers of skin, the epidermis, has been damaged and the deeper layers of the skin are also affected.

Skin is unable to regenerate itself exactly as it was so the wound is replaced by granulation tissue which is made up of collagen fibres. These fibres fill the wound from the inside out and help to heal the damaged area of skin. This replacement tissue may heal the injury, but can also remain visible.

Certain factors can also increase the chances of developing acne scars or increasing their appearance, for example:

  • Genetics: If your parents had acne when they were younger, you may have higher chances of developing acne.
  • Sun exposure: The sun's rays trigger the production of melanin in the skin, which can make acne scars darker and more noticeable.
  • Puberty: One of the side effects of the hormonal changes our bodies go through during puberty is acne. Picking at blemishes can leave scars, however if the acne is severe, there may be scars left even if the acne was left untouched.
  • Gender: While both men and women can develop acne, men tend to develop more severe acne due to the hormone androgen.

Types of acne scars

There are several different types of acne scars. The following are those most closely associated with acne:

Atrophic scars

Ice pick scars are one of the types of acne scars
Acne can cause atrophic scars known as ‘ice pick’ scars

These are pitted or sunken scars and are sometimes referred to as 'ice pick scars'. They develop when a wound does not heal correctly and too little binding tissue is formed. The scar then develops beneath the surrounding tissue and a small, visible indentation (dimple) develops.

Hypertrophic scars

You can recognise hypertrophic scars from an elevation in the skin or scar tissue. Where there was previously an inflamed blemish, the skin produces ‘inferior’ tissue. This doesn’t have the same structure as healthy tissue and therefore becomes thicker and sits above the surrounding skin. 


When a hypertrophic scar continues to grow and spreads into other areas of the skin it is known as a keloid. Keloid scars are raised and are a reddish purple when new but then fade. This form of scar is only occasionally caused by acne, it is more commonly associated with burns.

How to prevent acne scars

The main way to prevent acne scars is to not pick or damage the skin while the acne inflammation is still active, however for some acne sufferers, this is a lot easier said than done. In severe acne cases, there may still be scarring left behind from the inflammation itself.

Another way to reduce acne scarring is to treat acne as soon as it develops in order to reduce inflammation. We recommend using the Eucerin DermoPurifyer range, which uses scientifically-tested ingredients to treat the root causes of acne, and following a skincare routine for acne-prone skin.

Treatment should only take place once your acne has healed

Sadly, it is not possible to remove scars completely, but they can be significantly reduced and made much less noticeable. It is also possible that your skin will improve itself over the years. 

If you decide your scars need treatment, there are various options available. The right option for you will depend on the nature, size and form of your scarring. Those which involve invasive treatment should be discussed with your doctor, and no treatment should start until your acne has completely healed.

Eucerin DermoPurifyer Triple Effect Serum, with patented Thiamidol, reduces post-acne marks, blemishes, and controls shine. First visible results in 2 weeks and continuous improvement over time. This has enhanced efficacy when used together with the DermoPurifyer Protective Fluid SPF 30.

Laser treatment for acne scars

Laser therapy triggers skin’s own healing process

With laser therapy, the skin is injured in a targeted way so as to activate its natural self-healing process. Once skin is renewed, the complexion appears smoother. There is a wide range of laser variants available and this treatment should only be conducted by an experienced dermatologist in order to avoid injuries to surrounding skin. Unfortunately, again, multiple sessions are required for visible, long-lasting results.

Microneedling for acne scars

There are devices available for home use, but microneedling is best and safest when carried out by a dermatologist or beautician to avoid the risk of further inflammation.

Facial skin is treated with a dermaroller. A dermaroller is a device fitted with numerous fine needles no more than 0.5 mm in length. These needles pierce the top layer of the skin, which sends a signal that there has been an injury that needs to be repaired. Skin responds by releasing more Collagen, Elastin and Hyaluronic Acid and, in just a short time, skin can appear tighter, younger and fresher.

Chemical peels for acne scars

Peels remove the outermost layers of skin

Specialists (dermatologists and/or beauticians) can treat acne scars with peels. Fruit Acid, Salicylic Acid or Trichloroacetic Acid (TCA) are used, in varying concentrations, to remove the outermost layers of skin. As skin heals, scars may be less visible and your complexion will be smoother and more even overall. 

Microdermabrasion for acne scars

Microdermabrasion can help with acne scarring on dry skin

This is a relatively gentle form of dermabrasion where the upper layers of the skin are removed mechanically with the help of small crystals. The treatment has a positive effect on the complexion and is suitable for dry skin, large pores or other scars too.

Microdermabrasion is pain-free and is usually carried out by a beautician. You’ll need to have regular treatments to achieve effective and lasting results.

Fruit acids for acne scars

Fruit acids are frequently used to treat skin marked or scarred by acne. Milder concentrations (up to 12%) are available for home use whereas beauticians have access to concentrations up to 40% and dermatologists can use concentrations up to 70%. Your dermatologist will be able to advice on the most appropriate concentration for your skin. Several peels are normally required before results are noticeable.

N.B. Skin can be very sensitive after a chemical and/or fruit acid peel, so it’s important you avoid direct sunlight (and solariums) and apply a high sun protection factor such as Eucerin Sun Gel-Creme Oil Control Dry Touch SPF50+.


massaging acne scars
Creams and massage can help to reduce acne scars

Retinol is a popular ingredient used in skincare products and treatments. It increases the turnover rate of skin cells while also reducing oil production which makes it very effective, not only at treating acne, but also at helping minimise the appearance of acne scars. Retinol molecules are very small, allowing them to penetrate the middle layer of skin and stimulate collagen production, which helps plump the skin. Additionally, increased cell turnover can result in a more even skin tone.

Nevertheless, retinol must be introduced to skin gradually to prevent irritation or skin purging. It is recommended to start by using a gentle formula once a week, building up the frequency after two weeks to twice a week, then three times a week and so on.

If none of the above treatments have been effective, contact your dermatologist for expert advice.

How do acne scars affect skin health?

An acne scar differs from the surrounding skin in the way it looks and behaves. 

Oil or sweat glands cannot reform in the scar tissue, and hair is unable to grow on it. Scar tissue also has fewer elastic fibres, so skin often looks and feels harder. Circulation and moisturisation are also compromised in scar tissue, making it harder for scarred skin to maintain the levels of hydration it needs and it can dry out. 

How long does it take for acne scars to fade?

Acne scars won't disappear entirely on their own but they can be reduced with treatment. The time it takes for them to fade depends on the type of acne scars, described above.

Post-inflammatory hyperpigmentation or redness usually takes anywhere from two months to two years to fade, so patience will be required. To help prevent acne scarring you should use Eucerin acne products to reduce breakouts.
