Guido Luca Ferrero was born in Turin on 18 May 1537, the son of Sebastiano Ferrero, signore of Casalvolone and Villata, and his wife Maddalena Borromeo, daughter of Federico Borromeo, 6th count of Arona and a member of the House of Borromeo. He was the grand-nephew of Cardinals Gianstefano Ferrero and Bonifacio Ferrero; the nephew of Cardinals Filiberto Ferrero and Pier Francesco Ferrero; and the cousin of Cardinal Charles Borromeo.

Pope Pius IV made him a cardinal deacon in the consistory of 12 March 1565. He participated in the papal conclave of 1565–66 that elected Pope Pius V. He received the red hat and the deaconry of Sant'Eufemia (a titular church declared a deaconry pro illa vice) on 8 February 1566. On 6 March 1566 he opted for the deaconry of Santi Vito, Modesto e Crescenzia. He participated in the papal conclave of 1572 that elected Pope Gregory XIII.
