Chemical Reconstruction of Skin Scars (CROSS) with Tri-Chloroacetic Acid (TCA), is a simple but effective procedure to treat atrophic acne scars. We prefer using this technique to treat ice pick scars.
Tiny amounts of concentrated TCA (70 to 100%) is applied onto the surface of the atrophic scar. This causes an inflammatory reaction in the area, leading to collagen remodelling.
This collagen remodelling and skin regeneration resurface the skin; resulting in the depression becoming shallower and scar shadowing lightened.
It’s important to note that it is not possible to restore the scarring to its former state.
Depending on the number of scars, this is a relatively simple procedure that can be completed in a matter of minutes.

Pre- Treatment Instructions: Always inform your doctor of all medications, including supplements you may be taking as well as your medical history. If you have had cold sores, you must also inform the doctor at least a week before as preventive treatment may be required.
Plan ahead. Schedule your treatment at least 1 week and a half prior to any special event as it may take 7 days or more for full recovery. Avoid any ablative lasers and/or excessive sun exposure/sun tanning at least 1 month before treatment.
Post- Treatment Instructions:
We recommend a minimum of 3 treatments done at a 4-8 week interval for optimal results.
Although rare, some risks may include:
An extended period of skin irritation and redness.
Damage and potential scarring of sensitive skin areas if TCA is accidentally deposited.
Temporary hyperpigmentation (PIH) or permanent hypopigmentation.
Scars coalescing into larger scars.
Skin discolouration, mainly in darker-skinned individuals.
TCA CROSS is suitable for any healthy adult looking to treat deep ice pick scars.
