What's the recovery like for TCA Cross?
Everything you need to know about TCA Cross recovery — timeline, tips, what to avoid, and when to call your provider.
Typical downtime: 5–7 days of small crusting at treated scars
Recovery timeline
Day 1
Treated scar sites immediately frost white, then turn red. Small spots are visible.
Days 2–5
Treated spots form small crusts or scabs. Do not pick — allow them to heal naturally.
Days 5–7
Crusts fall off, revealing pink skin underneath. Treated scars look temporarily more inflamed before the healing response takes effect.
Weeks 4–12
Scar gradually fills from the bottom up. Improvement is often visible within 4 to 6 weeks per session.
Recovery tips
- Do not pick at crusts — allow them to fall off naturally
- Apply prescribed healing ointment to keep treated spots moist
- SPF 50+ is essential on treated areas as soon as crusts fall off
- Avoid anything that increases skin inflammation (retinoids, exfoliants) until fully healed
What to avoid
- Picking at crusts or scabs
- Sun exposure on treated areas for at least 2 weeks
- Active skincare (retinoids, acids) for 2 weeks
- Sweating heavily or getting treated areas wet for the first 48 hours
When to call your provider
- Signs of infection at treated scar sites: increasing redness, pain, swelling, or fever
- Significant hyperpigmentation developing at treated sites after crusts fall off
- Scarring or texture worsening rather than improving after 4 to 6 weeks
