Written by Ramona Sinha, Certified Skin Care Coach

Have you gotten rid of your acne but still have scars? When the evidence of a history of agony and anxiety remains on your face, you will likely feel like the acne never really went away. Fortunately, there is a solution – dermal fillers for acne scars. This procedure is performed by a professional or a doctor who injects collagen or hyaluronic acid fillers into the scars. Keep reading to learn everything about this procedure!

What Are Dermal Fillers For Acne Scars?

Dermal fillers add fullness to acne scars and help minimize their appearance. Ingredients like collagen, hyaluronic acid, and polymethyl-methacrylate microspheres (PMMA) are injected into the skin to plump up the scars and soften their appearance.

The Procedure

The process starts with a consultation with a registered doctor or dermatologist. They will inspect your skin and inquire about your medical history and any allergies that you may have.

The doctor will recommend one of two dermal filler options based on your answers. They will inject 0.5 mL of the product into your skin, just below your scar. However, the amount of product or filler may vary, depending on the size and indentation of your scar.

It will take up to two weeks for the fillers to noticeably minimize your acne scars. During this time, you have to follow the after-care guidelines provided by your doctor.

Dermal fillers may last for 6-8 months, after which you may have to go for a second procedure. This is not a one-time solution for acne scarring.

There are several in-office procedures like laser treatment, dermabrasion, and chemical peels. However, several factors make dermal fillers a better option than the others.

Why Go For Dermal Fillers?

The major USPs of dermal fillers are:

  • They do not cause much discomfort. However, it depends on your pain tolerance levels.
  • You will see immediate results as the downtime for healing is less than other procedures.
  • The effects may last for a relatively long period (6-8 months) with additional care. You may have to go for the procedure once a year.
  • It lifts the indented skin and improves the skin texture.
  • Some fillers may help the skin produce collagen that gradually minimizes the scars appearance.
  • The risks are minimal. You may experience mild bruising and swelling, but they go away within a few days.
  • While more research is required for this, dermal fillers seem to have a higher success rate for certain acne scars than other procedures.

Fillers work amazingly for indented scars. Take a look.

Dermal Fillers For Acne Scars: Before And After

Dermal fillers for acne scars

There are different types of dermal fillers available on the market. They are made of different ingredients and can be used for acne scars and other facial improvements.

Types Of Dermal Fillers Available For Acne Scars

Two major types of dermal fillers are used to improve acne scars:

1. Hyaluronic Acid Fillers

Our body naturally produces hyaluronic acid to maintain the skin’s hydration levels. Dermatologists may use different variations of this filler to ensure a clean finish.

Some of the popular hyaluronic acid dermal fillers include Belotero, Radiesse, and Restylane. Restylane fillers last for 6-9 months, Belotero can last up to 12 months, while Radiesse may last for around 15-24 months.

2. Collagen-Based Dermal Filler

Collagen was the first material approved by the US FDA (United States Food And Drug Administration) for dermal fillers (1). Bellafill is the most commonly used collagen-based filler. It is used to fill pitted and severely indented scars and contains 80% collagen and 20% polymethylmethacrylate (PMMA), a semi-permanent filler.

Collagen fillers replenish the lost natural collagen in the scar and restore its support structure. However, dermal fillers do not work for all acne scars. Keep reading for more details.

Do Dermal Fillers Work On All Acne Scars?

No. Derma fillers work only on atrophic scars. Acne scars are of two types:

  • Atrophic Scars: These are flat and cause depressions on the skin. The different types of atrophic scars include boxcar, ice pick, and rolling scars.
  • Hypertrophic Scars: These are raised bumps of scar tissue.

Dermal fillers may cause a few side effects. Check out the next section.

Side Effects Of Dermal Fillers For Acne Scars

You may experience mild side effects immediately or after a week of the procedure. The symptoms include:

  • Redness
  • Itching
  • Red boils
  • Swelling
  • Bruising
  • Rashes
  • Mild pain

In most cases, these side effects go away on their own. To avoid any serious damage, avoid exfoliating your skin with physical scrubs or facial acids. Inform your doctor if the side effects do not subside after two weeks.

When considering dermal fillers for acne scars, make sure that you meet the criteria mentioned below.

Who Can Use Dermal Fillers For Acne Scars?

You may go for dermal fillers if

  • You are over 21 years of age.
  • You have deep acne scars.

It is better to consult a dermatologist and get your scars and skin evaluated before opting for dermal fillers. Avoid the fillers if you have cuts and wounds on your skin.

Key Takeaways

  • By adding fullness to acne scars, dermal fillers minimize the scars’ appearance.
  • With additional care, their effects may last for a relatively long period (6-8 months).
  • Hyaluronic acid fillers and collagen-based dermal fillers are the two major types of dermal fillers.

Acne scars can make one anxious and distressing to look at. The good news is you can opt for dermal fillers for your acne. This is a cosmetic procedure where your doctor injects your acne scars with hyaluronic acid or collagen to boost the healing of the scars. These reduce the appearance of scars and show visible results almost immediately. However, dermal fillers only work on atrophic and hypertrophic scars. You may experience mild side effects after the procedure such as swelling, redness, or bruising which go away on their own in some time. Consult your doctor if these side effects persist after two weeks.
