General Recommendations
for the TCA CROSS
Pre-treatment
Use Proper Sun Protection:
Apply SPF 30+ with physical filters every 2 hours for a minimum of 2 weeks before the treatment.
Ensure your skin is not sunburned, and you do not have any cold sores before treatment.
Avoid Skin Irritants:
Your skin must be non-irritated for the procedure.
Do not wax, use hair removal products, undergo laser hair removal, or use scrubs on the treatment area before your appointment.
Discontinue Prescription Skin Products:
Stop using prescription skin products 5 days before the treatment.
Post-Treatment
Day 1: Do not cleanse your skin.
Apply a thin layer of Vaseline to the treated areas.
Day 2–5: Cleanse your skin gently using a mild cleanser, then rinse thoroughly with water.
Continue applying Vaseline to keep the skin protected.
Avoid using moisturizer, SPF, makeup, masks, swimming, or smoking during this period to prevent irritation and infection.
Day 6 – Month 3: Apply SPF 30+ with physical filters and reapply every 2 hours when outdoors. Wear protective hats and avoid sun exposure, as failure to do so can result in permanent brown discoloration.
You may resume your regular skincare regimen, including retinoids, 10 days after the procedure.
If hyperpigmentation occurs, begin using a fading cream, such as hydroquinone, starting on day 7.
Consider laser treatments to expedite recovery, improve scarring, and reduce residual pigmentation.
Maintenance
Follow the plan developed by your specialist, as timing is important for achieving results.
Continue with the skincare routine tailored for your skin.
Apply and reapply SPF every 2 hours if outside.

FAQ
TCA CROSS involves applying a high concentration of TCA directly into the scar tissue, causing a localized inflammatory reaction that leads to the formation of new collagen and subsequent elevation of the scar
It is recommended to avoid strenuous activities, including going to the gym, for at least 72 hours after treatment to prevent excessive sweating and irritation to the treated area.
Most people can resume their normal activities immediately after treatment, but you may prefer not to go back to work because your skin will be covered with ointment.
It is crucial to avoid direct sun exposure for at least two weeks after the treatment. Always use a high SPF sunscreen when going outside to protect your skin from UV damage and reapply it every 2 weeks.
Post-inflammatory hyperpigmentation (PIH) can occur, especially in individuals with darker skin tones. Proper post-treatment care, including sun protection and gentle skincare, can minimize this risk.
Pigmentation typically fades over time, usually within a few weeks to a few months. Using recommended skincare products and protecting your skin from the sun can help speed up the process.
