What it is
A focal high-strength TCA technique used for carefully selected ice-pick acne scars.
A small amount of TCA is placed directly into selected scars to trigger controlled remodeling.
Who it may suit
People with a clinician-confirmed pigment, redness, texture, pore or scar concern suited to the selected wavelength or device.
Who needs extra review
Recent tanning, active infection, photosensitising medication, uncontrolled skin disease or a high pigment-change risk require medical review.
Planning and results
- Common areas
- Individual deep, narrow acne scars
- Sessions
- Often planned as a series because pigment, redness, scars and pores respond differently. Diagnosis comes before session count.
- When results may appear
- Redness or darkening can appear first. Improvement may develop over weeks and often requires more than one visit.
- Downtime
- Frosting and crusting are expected; prolonged redness and pigment change can occur.
