Deep, pitted scars—such as those left behind by acne—can be difficult to treat with standard resurfacing methods. TCA Cross (Trichloroacetic Acid Chemical Reconstruction of Skin Scars) is an advanced, targeted treatment that helps rebuild collagen and smooth out scarred skin by stimulating deep skin renewal.

At Metropolis Dermatology in Costa Mesa, CA, we specialize in TCA Cross treatments to help patients achieve more even skin texture and reduced scar depth—without the need for surgery or extensive downtime.

What is Scar Treatment (TCA Cross)?

TCA Cross is a highly precise chemical treatment that targets individual depressed scars by applying a high concentration of trichloroacetic acid (TCA) directly into the scar tissue. This method triggers collagen remodeling and skin regeneration, gradually raising the scar to be level with the surrounding skin. This treatment is particularly effective for:

  • Ice-pick scars: Deep, narrow scars that extend into the skin.
  • Boxcar scars: Broad depressions with defined edges.
  • Stubborn acne scars: Scars that have not responded well to other treatments.

By focusing directly on each scar, TCA Cross allows for controlled, targeted healing while keeping surrounding skin intact.

 

How Does Scar Treatment (TCA Cross) Work?

  • Personalized Assessment: Your skin is evaluated to determine if TCA Cross is the best option for your scars.
  • Precise TCA Application: Using a fine applicator, a high-strength TCA solution (70 to 100%) is carefully applied to each individual scar, creating a controlled chemical response.
  • Scar Tissue Reactivation: The acid penetrates deep into the scar, triggering a temporary white frosting effect that signals the beginning of collagen production and tissue repair.
  • Collagen Remodeling: Over the following weeks, new collagen fills in the scar, leading to smoother, firmer skin.

TCA Cross works gradually, and multiple sessions are typically needed to achieve optimal improvement.

 

Importance of Scar Treatment (TCA Cross)

  • Highly Effective for Deep Scars: One of the most successful treatments for ice-pick and boxcar scars.
  • Stimulates Long-Term Skin Repair: Boosts collagen production for continued scar improvement over time.
  • Precise, Focused Treatment: Targets scars individually without damaging surrounding skin.
  • Minimally Invasive, Non-Surgical: No incisions or extended downtime.
  • Improves Skin Texture and Evenness: Helps refine the skin’s surface and promote a smoother, more uniform look.

FAQs

How many TCA Cross sessions are required?
Most patients need 3 to 6 treatments, spaced 4 to 6 weeks apart, depending on the depth and severity of scars.

Does TCA Cross hurt?
Patients may feel a brief tingling or burning sensation, but it fades quickly. A cooling treatment may be applied afterward to enhance comfort.

What can I expect after treatment?
After TCA Cross, treated areas may scab, peel, or appear slightly red—this is part of the natural healing process. Most recover within a few days.

Can TCA Cross be combined with other treatments?
Yes! TCA Cross can enhance results when paired with microneedling, laser resurfacing, or fillers.

Are there any risks?
Mild redness, peeling, or temporary pigment changes may occur, but these typically resolve with proper aftercare.

I love Dr Higgins ! I’ve been a patient with her for the last two years. I originally came to see her because I was struggling with painful hormonal acne and a lot of hyper pigmentation issues. Two years later my skin is GLOWING and my confidence is up! Dr Higgins is so warm, friendly, and knowledgeable. She cares for all her patients like they are her family. I even come to the office twice a month now to see Bella for extraction facials that are covered by my insurance (incredible! unheard of! a $30 professional facial!). The team at the front desk are so sweet and also make sure that my favorite snacks are stocked in the waiting room when I come in, and are always really helpful when I need to coordinate my medication refills. I have recommended lots of my friends to see Dr Higgins for everything from acne issues to hair loss treatments. Dr Higgins is such a gem and I’m so happy I found her !

Quick, professional, and thorough! I was in and out within 20-30 minutes from arrival time. They resolved all of my issues regarding my skin as well as provided detailed information on recovery and treatment. I’ve already referred other patients who also had similar experiences.
