Eyelash extensions are safe but make sure to go to an experienced and reputable place. Do your research-- this is a delicate area and the procedure is very tedious.  You want to be sure that it is a sanitary place because eye infections can certainly occur if it's not. 

While they look great, extensions can be very expensive and usually only last up to a month with a touch-up necessary in between treatments. Latisse is a good, more cost-effective alternative. The downside is you may encounter redness and irritation. Much less likely is an irreversible side effect of iris pigmentation. 

Also, realize that you will unlikely to have your own lashes grow as long as eyelash extensions can be. Also, you may encounter redness and irritation. If you really want to glam it up for an event -- go with the extensions. Latisse will most likely provide a more natural, everyday look.
