Acne Scar Treatment

Dr. Graber Discusses Acne Scar Treatment Options

Today, there are many types of acne scar treatments because there are so many types of acne scars! Two different kinds of discoloration can be left behind by acne. Post-inflammatory erythema is a type of red discoloration, while post-inflammatory hyperpigmentation is a type of brown discoloration.

Acne can also leave depressions in the skin (known as atrophic scars) and thickening of the skin (known as hypertrophic or keloid scars). Because you may be experiencing multiple types of acne scarring, a combination of treatments may be necessary. Your dermatologist will help you decide which options work best for your skin.

Moreover, you should never shy away from the results you’re looking for. Understandably, acne and scarring skin can have a daunting effect on your self-esteem, but remember that these skin complications don’t have to be permanent. To get a clear idea of the various types of scarring on the skin, keep reading below for a comprehensive review of which type you may be experiencing. This will help you determine which acne scar treatment may be right for you.

Types of Acne Scars

Post Inflammatory Erythema (PIE):

Laser Acne TreatmentPIE is a type of acne scar that leaves small red marks on the skin in areas where there was previously an acne lesion. This redness is best treated with a laser treatment for acne scars called the Pulsed Dye Laser (PDL), otherwise known as the VBeam laser. Generally, a minimum of 2-3 treatments are needed for adequate results. Patients will notice that the treated areas are usually redder for a few days up to one week before beginning to fade.

This type of scarring is generally one of the most common as most people experience acne for years during their teens and even into adulthood. It can be harder to manage for some than others, and scarring can worsen over time, especially if acne reappears in the same areas over and over.

Post Inflammatory Hyperpigmentation (PIH):

PIH is a type of acne scar that leaves small brown marks on the skin in the areas where there was previously an acne lesion. It is more common to see this in people of darker skin types. Generally, PIH tends to fade on its own, but it could take over one year for some people. Often this type of discoloration is best treated with chemical peels. It may also be treated with the diligent use of prescription or over-the-counter lightening creams.

For those who struggle with acne, this can become a compounding issue leading to substantial skin discoloration in extreme cases. It may not pose a particular health threat, but there’s plenty you can do to get your skin back to a more uniform look. Although PIH may be more commonly found in those with darker skin types, this can happen to anyone, and the severity can also significantly differ.

Depressed Acne Scarring:

Acne Scarring


Depressed acne scars (also known as atrophic scars) are a type of acne scar that leaves small indents in the skin after an acne lesion has run its course. One or two spots may not seem like a big deal to most people, but others suffer from uneven skin that can be much more severe. As acne increases, this particular type of scarring can worsen for some individuals. However, finding treatment for acne spots comes with multiple solutions. This is an area of skin that can be smoothed over by multiple different techniques. Fractionated lasers are very safe and can help smooth skin in these areas. The treated area will be red and swollen immediately after treatment.On average, the skin will need 2-3 days to heal from the laser and return to normal. Generally, 4-6 treatments are needed, usually spaced apart monthly. 

Microneedling is another method that can be used to treat depressed acne scars. During this procedure, the doctor will use a device to poke many tiny holes into the skin surface and then apply a serum that promotes skin cell turnover and collagen production.Over time, this helps to smooth out the surface of the skin. Immediately after treatment, the area will look red and raw, healing in about 2-4 days. On average, patients require four or more treatments for complete results. 

Depending on the severity of the acne scars, it may take more than laser scar removal treatments to get the job done. Another option for treating depressed acne scarring is fillers. Fillers are gel-like substances injected right under the skin to fill in depressed areas of the skin. This helps to smooth out the skin. 

Thickened Scars (hypertrophic or keloid scars):

Laser Acne TreatmentThese types of pimple scars are due to thickened skin in the area of previous acne lesions. These can be treated with injections of a steroid solution which can help thin out a thickened scar. These lesions generally need multiple injections over time to completely flatten out. Microneedling is another method that can be used to treat thickened acne scars. During this procedure, the provider will use a device to poke many tiny holes into the skin surface, and then apply a serum that promotes skin cell turnover and collagen production. Over time, this helps to smooth out the surface of the skin. Immediately after treatment, the area will look very red and raw, which will heal in about 2-4 days. On average, patients require 4 or more treatments for complete results. Some hypertrophic or keloid scars may respond to a surgical procedure known as scar revision. Your dermatologist will let you know which is the best treatment regimen for you.

How To Avoid Scarring

Some cases of acne can be much more damaging than others, and even with over-the-counter or medicated acne treatments, it’s common for them to leave scarring behind. However, many scars people encounter over time could be due to face picking or forcing acne to end its life cycle early.

This can quickly increase the amount of damage done to the skin and, in many cases, will guarantee scarring after it heals. Of course, facial scars may be inevitable with more severe cases of acne, but you can do plenty to ensure it’s minimized along the way. All you can do is manage your facial hygiene and do your best not to pick at your acne, no matter how frustrating it may be.
