The chances of scarring are virtually zero if you are compliant with the aftercare instructions given to you by your treating clinician. Picosure was originally developed for the purpose of scar revision. The Picosure is now also FDA approved to treat acne scars, which further demonstrates its positive effects on scars. Anecdotally we have seen an improvement in scarring in tattoos, and have seen raised tattoos flatten. Even though Picosure may flatten out raised scarring, there may be pre-existing hypo-pigmentation (whitening of the skin) underneath the ink. Once the ink is removed, the hypo-pigmentation might become evident. This pigmentation was caused by an improperly done tattoo, and it will remain after the ink is removed.
