Targeted Chemical Treatment for Deep Acne Scars
Acne scars don’t have to define your skin anymore. With TCA CROSS in Los Angeles, Scar Healing Institute will directly target the foundation of your scars to restore smoother, healthier-looking skin from within.
For more dramatic improvements, Dr. Salar Hazany, our founder and board-certified dermatologist, created SHI CROSS, which uses phenol, a more advanced alternative to TCA that penetrates deeper, builds stronger collagen, and creates longer-lasting skin refinements.
Our innovative approach:
- Rebuilds structure beneath deep, stubborn scars
- Stimulates new collagen for visible scar elevation and smoother texture
- Protects surrounding skin for faster recovery and natural-looking results
With each session, your skin becomes clearer, firmer, and more radiant, leaving you with a complexion you’ll love to show off.
The Benefits of TCA CROSS Treatment
TCA CROSS (Trichloroacetic Acid Chemical Reconstruction of Skin Scars) treatments restore your skin from the inside out, creating smoother texture and a more balanced tone where deep scars once were. By stimulating natural collagen production, your skin becomes firmer, softer, and more refined with every session.
Here’s how our phenol treatments support your healthiest, smoothest skin:
- Noticeably smoother, more even skin texture
- Refined tone and minimized scar depth
- Targeted treatment that protects surrounding healthy skin
- Natural collagen stimulation for long-term scar improvement
- Minimal downtime compared to traditional resurfacing
- Enhanced results and deeper repair with our exclusive phenol CROSS technique
How to Know if TCA CROSS Is Right for You
TCA CROSS is best for those with deep, stubborn acne scars looking to restore a more even complexion. It’s not the right choice for everyone; we’ll assess your skin health, tone, and scar type to determine the best treatment approach for you.
You may be a good candidate for TCA CROSS if:
- You have deep, narrow acne scars (ice pick or boxcar scars)
- Your skin has fully healed from active acne
- You’re in good overall health
- You want noticeable skin improvements with minimal downtime
You should avoid this treatment if:
- You have active acne, open wounds, or skin infections
- You’re currently using strong exfoliating or retinoid products
- You have a history of keloid or hypertrophic scarring
- You’re pregnant, breastfeeding, or have certain medical conditions that affect healing
- You’re unable to avoid direct sun exposure during recovery
Results to Expect During and After TCA CROSS
During your phenol CROSS session, we treat each scar individually, using a fine-tipped applicator to deliver the chemical solution deep into the skin. You may feel a brief stinging or warming sensation as the acid reacts, but most patients describe it as mild and quick.
After treatment, your skin may look red or frosted where the solution was applied—this is a normal part of the healing process. Over the next few weeks, your skin will shed and renew itself as collagen production increases beneath the surface.
Here’s what you can expect:
- Days 1–3: Redness and mild swelling develop, followed by tiny crusts or scabs.
- Days 4–7: Scabs dry and begin to flake naturally. Avoid picking to protect new skin.
- Week 2: Most scabs fall off and fresh skin starts to appear.
- Weeks 3–4: New skin blends with surrounding areas, and tone evens out.
- Month 2 and beyond: Collagen continues to rebuild, gradually smoothing and lifting scars for ongoing improvements.
What You Can Expect During TCA CROSS in Los Angeles
TCA CROSS is a highly detailed procedure and requires the skill and expertise of a trained dermatologist to ensure both the efficacy and safety of the treatment. Below is a comprehensive overview of the process:
- Preparation: First, the skin is disinfected and cleansed of any oils. Then, it is left to dry completely to allow the peel to adhere properly to the acne scars.
- Application: Highly concentrated TCA is applied little-by-little into each individual scar with a fine-tipped instrument. This method spares the surrounding healthy skin.
- Neutralization: TCA CROSS self-neutralizes, unlike some other chemical peel procedures, so there is no need for neutralizing solution.
- Immediately After: As the acid seeps into the skin, the treated acne scar areas may turn white. This is normal and typically disappears within a few hours.
- Monitoring: The dermatologist will monitor the reaction and the treatment response, adjusting the application if necessary according to your skin type during subsequent sessions.
While both treatments involve the precise application of a chemical agent directly into acne scars, Phenol CROSS penetrates deeper into the scar tissue, leading to stronger collagen remodeling and more effective scar elevation. Additionally, unlike TCA, phenol has natural anesthetic properties, making the procedure less painful despite its increased strength.
Phenol CROSS is more potent, fewer treatment sessions are typically required to achieve visible improvements compared to TCA CROSS. This enhanced effectiveness is why Scar Healing Institute exclusively performs Phenol CROSS as the superior choice for deep acne scar treatment.
