This is a hilarious moment a spa owner pranked his loyal client with a fake eyelash extension.

JA Caberto, 25, placed a thick eyelash extension on Dina De Guzman, 66, while she was having the cosmetic treatment in Tarlac City, the Philippines, on September 26.

Footage shows the shocked woman's reaction when she looks in the mirror to see her new lashes.

Dina asked the eyelash technician prankster to make the eyelash thinner, as it was too thick. She laughed and expressed her dislike for her new appearance.

Later on, JA explained that it was all a prank, and he removed the fake eyelash extension from his shocked client's eyelid.

He said he was pleased with his customer's genuine reaction and her honesty.
