If youâve been researching acne scar treatments, youâve probably heard about TCA CROSS. Itâs one of the most effective options for ice pick and boxcar scars, especially those that havenât responded to other treatments.
But letâs be honestâif youâve got melanin-rich skin or are prone to pigmentation changes, youâve probably come across some warnings or Reddit threads talking about color changes after TCA CROSS. Maybe youâre worried about hyperpigmentation or hypopigmentation. Maybe youâve delayed treatment because youâre not sure whatâs normal and whatâs not.
We hear you.
At Qazi Cosmetic Center in Orange County, we treat patients from all skin tones and backgroundsâincluding Fitzpatrick types IV, V, and VIâand weâve seen firsthand how TCA CROSS can deliver amazing results when itâs done the right way, with the right precautions. That includes talking openly about skin color changes, realistic healing expectations, and how to minimize risks before you ever start treatment.
This article is your no-pressure, no-fluff guide to understanding what TCA CROSS is, how it affects pigmentation, and what you can do to keep your skin safe.
First Things First: What Is TCA CROSS?
TCA CROSS stands for Trichloroacetic Acid Chemical Reconstruction of Skin Scars. Itâs a technique that uses high-strength TCA (usually 50â100%) applied directly into deep acne scars, like ice pick or narrow boxcar scars.
Unlike lasers or peels that treat the entire face, TCA CROSS targets only the scar tissue, triggering collagen remodeling and helping the scar gradually lift from the inside out.
It's especially powerful for:
- Ice pick scars
- Deep, narrow boxcar scars
- Resistant scars that havenât improved with other treatments
This is a high-precision treatmentâand when performed correctly, it can change the texture and depth of scars dramatically over time.
The Big Question: Will It Change My Skin Color?
Letâs talk about what most patients really want to know:
âWill TCA CROSS leave behind dark marks or light spots?â
The honest answer is: it canâbut not always, and not permanently.
Hereâs what to understand:
1. Post-Inflammatory Hyperpigmentation (PIH)
After TCA is applied, the area becomes frosty white, then forms a scab that eventually falls off. Itâs completely normal for a dark mark (PIH) to remain after the scab heals. This is your skinâs response to inflammationânot a scar, and not permanent.
With the right post-treatment care, PIH usually fades in 4â12 weeks, depending on your skin tone and healing habits.
2. Hypopigmentation (Loss of Color)
This is much less common but can happenâespecially if the TCA is applied too aggressively or if the skin is over-treated. It shows up as a lighter patch in the treated area. In most cases, the skin re-pigments slowly, but in rare cases, it can be longer-lasting.
At Qazi Cosmetic Center, we minimize this risk by:
- Choosing the right TCA strength for your skin tone
- Avoiding overlapping treatments too soon
- Giving your skin adequate healing time between sessions
Whoâs at Greater Risk for Pigment Changes?
While all skin types can benefit from TCA CROSS, the risk of pigmentation changes is higher in:
- Fitzpatrick Skin Types IV, V, and VI (medium to deep brown skin tones)
- Patients with a history of PIH or melasma
- Anyone who doesnât wear daily sun protection
- Patients who pick or peel the scabs during healing
This is why we always prep your skin ahead of time and guide you on how to protect it afterward.
How to Minimize Pigmentation Risks After TCA CROSS
If youâre thinking about getting TCA CROSSâor youâve already started sessionsâhere are some steps that really matter when it comes to reducing color changes:
Use a pigment-suppressing regimen before treatment:
- Products with azelaic acid, niacinamide, or tranexamic acid can help calm melanocyte activity
- Avoid active acne or irritation before treatment to keep inflammation low
Stick to post-treatment care:
- Let the scabs fall off on their own
- Avoid picking or rubbing
- Use healing moisturizers and gentle cleansers
Commit to sunscreen:
- Apply broad-spectrum SPF 30+ every day, even indoors
- Reapply if youâre sweating, outside, or near windows
Space out your treatments:
- Donât rush into back-to-back sessions
- Give your skin time to recover and pigment to settle before deciding whatâs âleft behindâ
What About Results? Can Skin Color Return to Normal?
In most cases, yesâespecially if pigment changes are mild and addressed early.
If post-TCA color changes do happen, we have tools to help:
- PicoSure Pro for pigmentation
- Excel V for redness or dark patches
- Topical fading products for stubborn spots
- Ongoing support and reassessment throughout your treatment plan
We want results to look good in all lightingânot just when your skin is freshly moisturized. That means keeping the tone, texture, and contour of your skin in syncânot just improving the scar depth.
