Algésiras was born in Central Africa, and became interested in comics through her parents. She became familiar with the work of Corben, Quino and Breccia through magazines like Pilote and Métal Hurlant. She was fascinated by fantasy in all forms: horror, gothic, and science-fiction.
Encouraged by her drawing teacher, she entered the Academy of Fine Arts in Angoulême. At this academy, she grew more familiar with comics and European comic artists. In the late nineties, Algésiras started his series 'Candélabres' at Delcourt.
