Hyperbole is used when Shakespeare is speaking about his mistress. He is actually over exaggerating how ugly and repulsive his mistress is. He is saying that she doesn't have a lovely blush to her face when he says "But no such roses see I in her cheeks." He is also saying that her breath is awful when he contrasts her breath to nice perfume and says "than in the breath that from my mistress reeks."
