Tca cross Bams MemberMember1(@bams) Posted : 02/08/2020 7:51 pm I did a tca cross in one scar hole.I use 60 percent of TCA. today is my sixth day. scar looks wide and blackish pink, is this normal? I am very afraid Quote Dodgerguy MemberMember72(@dodgerguy) Posted : 03/08/2020 9:42 pm TCA CROSS can make scars wider with some discoloration. There's always risk with TCA but at least you're starting off at a lower concentration. The thought is each time you apply the TCA the scar lifts. Quote
