Specialist Dermatologists at the Acne Specialist Clinic perform a technique of chemical peeling to treat deep acne scars. Deep ice pick scars respond poorly to Fraxel/ Lasers however can be addressed with TCA peels.
TCA CROSS chemical peels can be safely used in all skin types, and in our hands has an excellent safety profile. If performed correctly, this method is an excellent method to treat selected acne scars. We tailor the concentration and technique of chemical peeling according to the skin type and depth of acne scars.
TCA CROSS is the most successful treatment for deep acne scars, this simple procedure outperforms even the most powerful and latest lasers.
I had two laser treatments performed at another center. The doctor wasn’t a Specialist and I had very little improvement. Two sessions of TCA peels with Dr Lim and I can’t believe the improvement.
I couldn’t believe the outcome of the TCA peel for my deep scars- and the procedure was totally painless.
Mixed Acne Scars
Ice Pick Scars
TCA, or Tri-Chloroacetic Acid, applied at a very high concentration stimulates collagen formation from the bottom of a deep acne scar. This collagen formation is gradual, and over 2-3 treatments, collagen fill up from the depths of the pick scar. The concentration of TCA will vary between skin types, and depth of scarring. TCA CROSS at the Acne Specialist Clinics range from 30% TCA to 100% TCA.
Scars are mapped an photographed before any treatment. This provides a record for both patients and the treating Dermatologist. Under sterile conditions in a procedural room, the treating Specialist uses an applicator to instill a tiny amount of TCA into the base of the scar. Each scar is treated individually. On average it take between 20-30 minutes to perform a session of TCA cross. The procedure itself is very well tolerated, with little discomfort.
After the procedure we use a healing balm or an antibiotic ointment to cover up the treated acne scars.
You will be prescribed an antibiotic to take for 5-7 days following TCA Cross, as this can prevent any secondary infection.
Deep ice pick scars respond poorly to Fraxel/ Fractional lasers. TCA cross is the treatment of choice for deep scars like this
Immediately following TCA cross, the treated skin turn white. Over a few hours, the area becomes much redder than the surrounding skin. Pin-point areas surrounding the treated area may peel over the next 3-4 days. The skin slowly returns to its normal colour over 8-21 days. In darker skin patients, pigmentation changes maybe more prolonged. It is essential that sun exposure is avoided in all patient for at least 2 weeks following a TCA chemical peel.
Recovery is also dependent on the strength of the TCA CROSS chemical peel- a higher concentration means a longer recovery time.
As with many other acne scar treatments, multiple sessions are advised for the best results. As a guide we encourage patients to complete 2-3 sessions, over a period of 3-4 months. Very deep scars can be treated with surgical techniques during the time of TCA Cross, whilst laser can also be conducted during the procedure. Individualized treatments will give the best results.
As a guide we should aim for at least 50-80% improvement of deep ice pick scars after a series of 2-3 TCA cross chemical peels. Scar specialists do not recommend fractional laser resurfacing for deep ice pick scars, as TCA peels or punch surgical excision out performs lasers in this setting. Once deep acne scars are raised up to form a shallow scar, we then use laser to complete the scar revision process.

After 2 sessions of punch excision, TCA cross, subscision treatments. Dr Davin S. Lim
Yes. Specialist often combine a number of techniques to give the best possible results to patients. We can combine subscision, punch excision, punch elevation, laser and TCA cross. Remember, most patients will have a number of different types of scars, and hence a combination of treatments will be needed.
TCA cross for acne scars forms an integral part of our Synergy Program for acne scar revision. The concept is to map and treat each scar individually, using the best method available for the scar type. Once the depth of scars are in the same plane, laser treatment can finish off the treatment.
TCA cross can be used to treat acne scars in all skin types. Darker skin patients may develop slight darkening of the treated skin (1-2mm areas), but this fades over a period of weeks. Occasionally post treatment darkening may last a few months. The use of sunscreen after this procedure is very important.
Treating acne scars in darker skin types can be more challenging as post -treatment darkening of the skin can be encountered. As a guide, Specialist recommend that an extra one or two treatments be performed, as a lower concentration of TCA is used in darker skin patients. Often we will prescribe a bleaching agent before and after the TCA Chemical peel procedure, as this can fade darkened scars.
The cost of this procedure will vary depending on the complexity of scars and the areas treated.
As a guide -
- $490 for small areas,
- $900 for larger areas.
- 2-4 treatments are needed for best results.
*Medicare rebate may apply for some treatments
We offer payment plans for acne scar treatments.

TCA cross is my favored method of treating deep ice pick scars. I often combine a few methods including punch excision and punch grafting with TCA cross in this situation. Fraxel and other Fractional lasers have minimal impact on deep ice picks. I always reinforce to patients that multiple techniques are needed for the best results. Very rarely do patients present with only one type of acne scar and hence a multiple treatment approach works best.
TCA cross can be used on all skin types including very dark skin patients. The idea behind this technique is to raise up deep scars to a level in which all scars are equal. This gives me the best chance to remove the remainder of acne scars with laser resurfacing, or RadioFrequency. For darker skin patients, an extra one or two treatments are needed, as the concentration of TCA is decreased.
