Verteporfin is a marketed drug with a good safety profile. Physicians use verteporfin off-label. In 2018, physicians described the off-label usage for Peyronie's disease as an interesting step. In 2021, scientists tested verteporfin to reveal if the drug would prevent scar tissue in skin. The testing of verteporfin on humans cleft lips was due to occur in late 2021.
