懸命 is a na-adjective 'strenuous / desperate,' sharing its core 懸命 with the four-character 一生懸命 — both rooted in the medieval samurai sense of 'risking one's life.' 生まれる here is metaphorical: 'born from X' = 'comes from / arises from X.' The から marks the source of origin. A poetic aphorism about the hidden cost of beauty.
