Acne Scars
Assessment of acne scars severity can be graded using Goodman and Baron’s qualitative acne scar grading system to allow objective pre and post-treatment comparisons.
1. Macular scars
Macular scars can be erythematous, hyperpigmented (brown) or hypopigmented (pale) flat marks. They do not represent a problem of contour like other scar grades but of colour.
2. Mild atrophic or hypertrophic scars
Mild atrophic (thin) or hypertrophic (thick) scars may not be obvious at social distances of 50 cm or greater and may be covered adequately by makeup or the normal shadow of shaved beard hair in men or normal body hair if extrafacial.
3. Moderate atrophic or hypertrophic scars
Moderate atrophic or hypertrophic scarring is obvious at social distances of 50 cm or greater and is not covered easily by makeup or the normal shadow of shaved beard hair in men or body hair if extrafacial, but is still able to be flattened by manual stretching of the skin (if atrophic).
4. Severe atrophic or hypertrophic scars
Severe atrophic or hypertrophic scarring is evident at social distances greater than 50 cm and is not covered easily by makeup or the normal shadow of shaved beard hair in men or body hair if extrafacial and is not able to be flattened by manual stretching of the skin.
How is TCA CROSS performed?
TCA CROSS is technically straightforward to perform and can be undertaken in a matter of minutes, depending on the number of scars to be treated. It is generally repeated on several occasions at 2 to 4-week intervals.
- The patient should be in a comfortable semi-recumbent position and remain still during the procedure.
- The skin is cleansed with chlorhexidine/saline-soaked gauze.
