How to avoid complications after TCA CROSS treatment such as pigmentation and widening scars? (photo)
TCA cross should be done carefully and under proper magnification to ensure accurate placement of acid. This can reduce complications associated with untoward spread/application of the strong acid beyond the scar, which can result in higher risks of post-inflammatory hyperpigmentation and scar widening.
That being said:
1. PIH is common after TCA in darker skins and should therefore be used wisely. Post-treatment skin care is essential, with sufficient recovery serums and sunscreen playing an important role.
2. Scars can appear to widen after TCA as the scars get shallower. As such, once the scars are shallow enough, laser resurfacing can then be used to further blend the scars.
Ensure you are followed up closely after your procedures and you should have a good response to treatment.
