TCA CROSS: What Is It and How Does It Work?

The chemical repair of skin scars (CROSS) using trichloroacetic acid is known as TCA CROSS. It is most commonly used to treat atrophic acne scars. It’s affordable, safe, and efficient.

The choice to do a TCA CROSS is based on the following factors:

  • Acne scarring’s type and severity
  • Preferences and expectations of patient
  • Clinician expectations and experience

TCA CROSS Is Effective In the Treatment Of the Following Forms of Acne Scars:

  • Boxcar scars
  • Rolling scars
  • Ice-pick scars

Combining Treatments with TCA CROSS

Treatments that can be combined with TCA CROSS for acne scars include:

  • Topical retinoids
  • Microneedling
  • Dermapen
  • Fractional laser treatment
  • Subcision

The Effects of TCA CROSS

When used correctly, TCA CROSS is moderately effective for atrophic acne scars. Patients may expect a 1- to 2-grade improvement in their acne scars over a 6-month period. Greater levels of patient satisfaction are associated with more severe pre-treatment scarring.

After the Procedure

The patient should be advised:

  • Frosting of the scar surface after treatment will last up to 12 hours
  • The skin around the treated sites will be red and sore for 24 to 48 hours
  • After 2 to 3 days a small scab will develop, which falls off after 3 to 7 days
  • He or she may wash as normal and may apply make-up if desired
  • Sunscreen is recommended to reduce the chance of pigmentation

Most patients require 3 to 6 treatments with TCA CROSS for optimum improvement. Treatments may be repeated at 2 to 8-week intervals over 6 months.
