TCA cross after microneedling.

Can I do the TCA cross 100% right after the microneedling(without fractional frequency )done ? Or do I have to wait longer to do the TCA cross?

TCA CROSS, micro needling and lasers

Depends. If I am doing individual scars ie. ice pick scars, then I often combine TCA CROSS, punch excision, energy based RF micro needling and Co2 laser in the one procedure, aiming to treat each scar type with a matched procedure. So - the answer is yes, it can be done with caution. All the best, Dr Davin S. Lim

TCA peel and microneedling

Thank you for asking about your TCA cross and microneedling.

  • First what is involved - 
  • The TCA cross uses 80% trichloroacetic acid to treat deep acne pit scars.
  • Microneedling places thousands of tiny punctures superficially in the skin to improve fine lines, superficial scars and skin texture.
  • So you do NOT want strong acid placed onto raw skin.
  • So the two can be done together ONLY if the TCA is applied first and has fully dried.
  • Otherewise the microneedling will drive strong acid under the skin and damage the skin.
  • To be completely safe, the two should be done separately but can be done at the same time by an experienced plastic or facial plastic surgeon or cosmetic dermatologist - who takes time to do it precisely.
  • I would not myself have this combination done by anyone else.
