Acne is a common skin condition characterized by blocked pores, pimples, cysts, and other lesions. Although it mainly affects teenagers, acne can occur at any age and most often appears on the face, neck, chest, back, shoulders, and upper arms.

After acne clears, many patients are left with discoloration and indentations on the skin. Severe acne, especially cysts or nodules, can cause scarring. These scars form when inflamed lesions rupture and release infected material into surrounding healthy tissue, damaging it and resulting in various types of scars. While acne scars are not harmful, their appearance often causes distress, prompting many to seek treatments to reduce or remove them.

Types of Acne Scars

Acne scars vary based on the severity and type of acne lesion, and each type may require specific treatments for effective skin repair.

Atrophic Scars:
These scars result from tissue loss. Ice pick scars are narrow, deep indentations resembling punctures, while boxcar scars are round, shallow or deep depressions similar to chickenpox scars.

Hypertrophic Scars:
Caused by excessive collagen production during healing, hypertrophic scars are raised areas of thickened tissue. Rolling scars, a type of hypertrophic scar, cause a wave-like texture due to bands of tissue pulling the skin downward.

Acne Scar Treatments

Treatment depends on scar type, severity, skin type, and desired results. Options include:

  • Tissue fillers to raise depressed scars
  • Dermabrasion to smooth the skin surface and reduce deeper scars
  • Laser therapy to remove damaged skin layers and stimulate new skin growth
  • Punch excision surgery to remove deep, indented scars, sometimes followed by skin grafting

Often, a combination of these treatments offers the best outcome, as addressing acne scars can be a complex, multi-step process.

Preventing Acne Scars

The best way to prevent scarring is to avoid developing lesions that cause scars. Patients should refrain from picking or popping pimples, as this increases the risk of infection and scarring. Picking at scabs should also be avoided to allow natural healing. Limiting sun exposure is important because UV rays can worsen skin damage and delay healing.

Some individuals are more prone to scarring despite preventive efforts, but numerous treatments are available to diminish scar appearance and rejuvenate the skin.
