What kind of scars does papular scar treatment address?

Treatment is for scars that remain as whitish or flesh-colored raised bumps where acne has settled. Their shape is the opposite of the more common pitted acne scars, so the approach is different as well. Not every raised mark is a papular scar, so at the consultation we first confirm which kind of scar it is and then decide on a method. What a scar is and why it forms is explained in the blog article What Is a Papular Scar?; this page covers the treatment method and the order in which it proceeds.

The Other Papular Scar

Cause

Excessive collagen proliferation and inflammatory response
Localized fibrosis and tissue degeneration after acne

Symptoms

Red, itchy, or painful, and tends to enlarge
Whitish or flesh-colored, raised, and remains unchanged

Conventional Treatment

Inflammation injections (steroids), long-pulsed laser
No active inflammation for the injection to act on (repeated injection can thin the skin)

The Other’s Approach

Compression and inflammation control
CO2 Pinhole Technique

Why do papular scars form on the chin?

A papular scar is left when fibrous tissue clumps locally and hardens in the place where acne heals. The nose and the area beside it are the most common sites, while the chin and jawline are places where hormone-influenced acne tends to recur. For that reason, on the chin a scar can form again if new acne keeps appearing even after the scar has been addressed, so scar treatment and acne management are considered together. Papular scars also occur on the forehead and cheeks but are uncommon there, and a raised lesion in those areas may be something else, so distinguishing it comes first.

How The Other Approaches It

CO2 Pinhole Technique

Treatment Interval

Every 8–10 weeks (enough time is needed for tissue to regenerate).

Recommended Sessions

At least 3 sessions (the number is decided at an in-person examination).

Precautions

The tiny scabs that form immediately after treatment should be allowed to fall off naturally.

What should I know about aftercare?

Right after treatment, a very small scab forms over the scar for several days. While the skin heals, we advise the following.

  1. Do not pick the scab; leave it until it falls off naturally. Removing it early may leave pigment behind or make the mark last longer.
  2. Wash your face as usual, but do not rub.
  3. Healing skin pigments easily, so use sunscreen even indoors.
  4. Wear makeup only after the scab has fallen off naturally.
  5. Put off exfoliating products, retinol, and high-concentration vitamin C until the scab has fallen off and the redness has settled, and moisturize generously.
  6. Avoid saunas and jjimjilbang, exercise that makes you sweat heavily, and alcohol for a few days.

If you notice unusual pain, discharge, or spreading redness, please contact us rather than waiting for your next appointment.

How do I tell it apart from other acne scars and marks?

Acne scars fall broadly into two types: pitted and raised. What people usually call acne scars are mostly the pitted kind, while a papular scar is the raised kind, so the approach is the opposite as well. Many people have both types on the same face, so different methods may be needed for different areas. A mark that is neither raised nor pitted but remains red or brown is not a scar; it is a pigment or vascular issue, so it is assessed separately.
