Beautifully curled lashes is a symbol of health and sexiness for centuries. And woman through history had many interesting, sometimes even dangerous, ways of curling them. From heating a spoon to applying many many coats of mascara, there is nothing that we haven't heard is the "trick" to a perfect curl.
There is a safe instrument we have used the last decades, the lash curler. Basically is a manual device that you use putting your lashes in and pressing so it would "fold" them creating a beautiful curl. Is a very safe technique but there are a few things to be careful and a few tips to make it work nicer.
Don't heat it. Many people heat the lash curler before using it with the purpose of making it last longer but is a very risky practice. You could easily burn or damage your lashes. A very good combination of lash primer, mascara and curler do a great job with no need for heat close to your eyelids.
Press the roots at the lash and not at the eyelid.
If your lashes are long, press two or three times in different places of the lash to get a better curl.
Curl them before applying mascara. That way you would set the curl.
If you can, don't curl them every day.
