WATCH: How to apply eyeliner with glasses on, according to Sharon Cuneta 

Sharon Cuneta posted her very first makeup tutorial on Instagram.

Just for fun, she asked her makeup artist to put eyeliner—which she fondly calls "tungkil"—on her without removing her eyeglasses. 

Watch this video:

"Habang nakasalamin ako at busy, ayoko tanggalin ang [salamin ko]," she explained.

In case you're wondering who "Juan" is, it's Juan Sarte, the popular makeup artist.

The Megastar has been vocal about her physical appearance lately. On a separate Instagram post, she shared that she has decided to keep her hair long since she's enjoying it.

"I have decided to keep the ganda ng mahabang buhok and keep my hair long!!! I have realized that I am far happier and more sunshine-y like this! Just never loved long hair on me so much. Ngayon ko lang ine-enjoy," she recounted.
