Acne can leave scars on the face and other areas. For some people, they are an unwanted reminder of a painful and bothersome condition. However, home remedies and medical treatments can help get rid of them.
Options for managing acne and reducing the appearance of scars include natural, over-the-counter, and prescription remedies.
Options will depend on the type and extent of scarring and include:
- chemical peels, such as salicylic acid
- retinoids and other creams
- laser treatment, microneedling, light therapy, and various other procedures
- surgery, in some cases
In this article, learn about various ways to help reduce the appearance of acne scars and promote healthy skin.
Suitable treatment options may vary slightly depending on the type of scarring that acne has caused. There are
These scars appear as small indentations in the skin.
- Icepick scars are small scars that look like pinpricks.
- Boxcar scars are larger indentations with clear edges.
- Rolling scars have unclear edges and give the skin a rolling or undulating appearance.
They occur when the skin does not make enough fibroblasts in the healing process. Fibroblasts are cells that play a crucial role in wound healing and collagen production.
These occur when the skin makes too many fibroblasts as the acne spot heals, causing a raised scar.
These are similar to hypertrophic scars but tend to be thicker than the original acne spot. There is often hyperpigmentation, making them darker than the surrounding skin. They may be red or brown. There may also be itching or pain.

Many people use natural remedies to help clear up acne scars. However, the science behind them is unclear. Some may cause further irritation or other problems so people should use them with caution.
Home remedies that people have traditionally used to treat acne scars include:
- black seed oil, which may help even out skin pigmentation
- rosehip oil, which has helped reduce discoloration in postsurgical scars
- honey, which

Various over-the-counter remedies can help reduce the appearance of acne scars. Products containing the following ingredients may be useful.
However, over-the-counter creams and lotions are unlikely to fully remove or flatten a raised scar.
Salicylic acid is a naturally occurring compound that is often an ingredient in acne skin care products. Salicylic acid peels help clear dirt, skin cells, and other debris that leads to acne from the pores of the skin.
It also helps reduce swelling and redness in the area, which may minimize the appearance of scarring.
Salicylic acid can help treat all scar types.
However, people with sensitive skin should do a patch test on a small area of skin before using it on their entire face, as it may cause dryness or irritation.
The authors also state that retinoids could help lighten hyperpigmented acne scars, including those in people with darker skin tones.
It is important to note that retinoids can make the skin sensitive to the sun. Anyone using retinoids for acne or scar treatment should wear sunscreen when going outdoors.
Alpha hydroxy acids
Alpha hydroxy acids (AHAs) can
AHAs are a mild form of acid that scrapes away the outer layer of skin to reveal fresh, new skin underneath. This process may help reduce hyperpigmentation due to scarring.
However, swelling, burning, and itching may occur at high concentrations. It is best to speak with a doctor before trying AHAs. They can help identify the best strength to use.
Lactic acid is
Lactic acid may also help lighten dark scar tissue, although it can
Many products for acne contain lactic acid. It is also present in diluted apple cider vinegar, which makes for a more natural, cost-effective treatment.
Experts do not know how these work, but they appear to help reduce the appearance and size of acne scars. They may do this by providing hydration. They can also reduce itching and pain and increase the flexibility of the skin.
A person will have to use the dressings all the time, which can be difficult on the face. Most people do not experience side effects, though some have itching and irritation.
Some medical treatments may help reduce acne scars.
A dermatologist can recommend a suitable procedure or combination of therapies depending on a person’s skin type and the extent of the scarring.
A dermatologist can recommend a type of peel that is suitable for a person’s skin type, acne severity, and scarring.
The authors of a
Other chemical peels may be less effective. For instance,
A person may need to try different types of peel to determine which one works for them.
Injections of corticosteroids may help soften and flatten raised acne scar tissue if a person has hypertrophic or keloid scars.
The treatment typically consists of a series of injections. A dermatologist can do these injections in their office once every few weeks, monitoring the results.
In some cases, dermatologists may recommend soft tissue fillers to treat atrophic acne scars. They may be particularly helpful for rolling and boxcar scars.
- collagen-based products
- hyaluronic acid
- poly-L-lactic acid
Depending on the filler, a person may need to repeat the treatment after some months. Hyaluronic fillers, for example, last around
Fillers can have adverse effects, but these will depend on the filler. Always speak with a doctor about the pros and cons before opting for treatment.
Microneedling is the process of inserting tiny needles into the skin surrounding the scar to stimulate the body to make more collagen. This collagen may reduce the appearance of atrophic acne scars by smoothing out the skin.
In a 2017 review, microneedling provided an improvement of
However, microneedling can cause side effects. Many people experience redness, pain, and inflammation after the treatment. However, these effects subside over time.
Laser treatment resurfaces the skin without the use of chemicals or scrubs. It removes the uppermost layer of skin to reveal the younger skin cells underneath, which can help reduce the appearance of scarring.
It can help reduce the appearance and texture of raised scars. Treatment with a pulsed dye laser can also help reduce the color of hyperpigmented scars.
Intense pulsed light treatment may be a better option for people with pale skin, according to the American Academy of Dermatology.
Laser treatment is not suitable for everyone. This will depend on the type of acne scarring and the person’s skin type. The treatment may also cause a reaction in some people, especially those with sensitive skin.
If other treatments do not help, surgery can remove raised acne scars. Surgery alone may not be enough to solve the problem, and a doctor may recommend further treatment.
Used alongside other treatments, this may help reduce the edges of boxcar acne scars, making the skin appear flatter and less indented. A doctor will use electric probes to heat the skin and kills the tissues that cause the edges around the scars.
Here are some answers to questions people often ask about acne scars.
How can I prevent acne scars?
It is not always possible to prevent acne or scarring, but people with acne can take measures to reduce the risk.
These include seeking treatment while acne is present and avoiding picking, popping, or touching acne, which may lead to infections and a higher chance of scarring.
How can I remove acne scars and discoloration?
Depending on the type and extent of scarring, there are various ways to remove or reduce acne scars. Fillers, for example, can help indented or atrophic acne scars. Laser treatment may reduce hyperpigmentation and flatten raised scars.
A dermatologist can help decide on a suitable option, depending on the person’s skin type and the extent and type of scarring.
Can treatment remove scars permanently?
Treatment can often help remove scars, but scars also tend to fade with time. How effective treatment will be will depend partly on the type and extent of scarring and the person’s skin type.
Treatment can be costly and time-consuming, and it is worth thinking carefully and talking with a dermatologist about what to expect.
Acne scars can be an unwanted reminder of acne and may reduce self-esteem in some people. However, treatment can often reduce their appearance.
