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

- 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.
