How to Heal and Fade Acne Scars After TCA CROSS Treatment in Hamilton, Ontario
TCA CROSS (Trichloroacetic Acid Chemical Reconstruction of Skin Scars) is a highly specialized acne scar treatment offered at DRS Skincare in Hamilton, Ontario. Unlike standard chemical peels, TCA CROSS uses a high concentration of trichloroacetic acid applied precisely into individual acne scars to stimulate new collagen formation and gradually lift and smooth depressed scars.
If you’ve recently had or are considering TCA CROSS treatment, proper aftercare is key to achieving smooth, even skin tone and minimizing pigmentation changes. Here’s what to expect and how to care for your skin as it heals.
What Is a Normal Reaction After TCA CROSS Treatment?
Immediately after your treatment, the treated scar areas may appear white or “frosted” for up to 12 hours. Over the next 24 to 48 hours, expect some redness, tenderness, or mild swelling around the scars. A small scab will form within a few days—this is a normal part of healing and typically falls off naturally within 5–10 days.
Important: Avoid picking, peeling, or scratching any scabs. Doing so can delay healing, worsen scarring, and increase the risk of post-inflammatory hyperpigmentation (dark spots).
How Should I Care for My Skin After TCA CROSS Treatment?
To promote optimal healing and collagen production, follow these TCA CROSS aftercare instructions:
- Do not wash the treated area for at least six hours after treatment.
- Apply a thin layer of prescription cream or ointment given by your doctor, or Aquaphor® or petroleum jelly to keep the area protected and prevent crusting.
- Avoid makeup and harsh cleansers until scabs have fallen off naturally
- Keep your skin cool—avoid saunas, hot showers, and strenuous exercise for at least 48 hours.
- Use a gentle, non-foaming cleanser once cleansing is resumed.
- Apply a fragrance-free moisturizer to support skin barrier repair.
Why Should I Avoid Exercise After TCA CROSS?
Heat and sweat can increase inflammation and delay recovery. Activities that raise your body temperature—such as heavy workouts, hot yoga, or long baths—can worsen redness and swelling. For best results, avoid intense activity for two days after treatment.
What Skincare Products Are Safe to Use During Healing?
Avoid products containing retinoids, exfoliating acids (AHA/BHA), scrubs, or alcohol until your provider advises that you can resume them.
Focus on barrier-supportive, gentle products such as:
- Mild cleansers (e.g., CeraVe Hydrating Cleanser, La Roche-Posay Toleriane)
- Non-comedogenic moisturizers
- Broad-spectrum SPF 50+ sunscreen daily
Sun protection is essential—your skin is extra sensitive to UV exposure after TCA CROSS. Limit direct sunlight and wear a wide-brimmed hat when outdoors.
When Should I Return for My Next TCA CROSS Session?
Most patients notice gradual scar depth and texture improvement as new collagen fibres form over several weeks. Depending on your skin type and scar severity, you may benefit from 3–4 monthly sessions for optimal results. We will usually pair TCA cross with other acne scar modalities customized to your specific issues to give you the best possible results.
Other treatments we often combine in the same session include:
- Subcision
- Injectable biostimulators (e.g., Sculptra®, Radiesse®)
- Microneedling
- Microneedling with radiofrequency, eg “Morpheus8“
- CO₂ laser resurfacing
