Is it OK to use the M2 Eyelash Activating Serum (EAS) after any surgical operation on or near the eyes? Can M2 Eyelash Activating Serum (EAS) also be effective on scar tissue?

Consult your doctor. The eyelashes on scarred skin are normally permanently damaged. The Eyelash Activating Serum (EAS) will probably not be able to take effect in this area.
