05ABOUT

Even with the same unevenness,The causes are different.

The underlying processes in the skin differ between acne and acne scars.

During your consultation, we’ll assess your skin condition and develop a personalized plan that combines treatments, skincare, and oral and topical medications based on your specific concerns.

The Difference Between Acne and Acne Scars

Acne is a skin condition in which pores become clogged due to sebum secretion, leading to inflammation.

Scarring can also occur if pores remain clogged for a long time.

What Remains Status
Dent Craters (acne scars). Icepick-type / Boxcar-type / Rolling-type
Excitement Keloid / Hypertrophic Scar
Post-inflammatory Redness / Post-inflammatory Hyperpigmentation

Three Types of Craters

Ice pick type

It is a small, deep indentation. The opening is narrow, and it extends deep into the surface.

Boxcar type

The bottom and sides are scarred. It is a square indentation with a distinct edge.

Rolling type

The tissue at the bottom is being pulled. It appears as a gentle, wavy indentation.

How Craters Form

A crater is not a hole caused by the skin's surface being scraped away.

When acne inflammation persists, hard tissue forms beneath the skin. This tissue pulls the skin's surface downward, resulting in indentations.

Things to Check During a Medical Examination

  • Will new acne breakouts occur?
  • Is the redness just starting, or has it been going on for a while?
  • Crater Shape and Depth
  • Degree of Fibrosis

We examine the skin in person to determine which layer to treat and how to proceed.

The number of treatment sessions you will receive as part of the trial program ranges from approximately one to three, depending on your symptoms.

PicoFocusPico-Fractional) is also effective in improving uneven acne scars that resemble craters.

Lara SecretThis is a body-only peel for the "back and genital area." It is not included in this trial program.

Frequently Asked Questions Before Making a Reservation

Q1. Which treatment is right for me?

During the examination, we will assess the development of new acne, redness, hyperpigmentation, and the shape and depth of acne scars.
