Some individuals have absolutely no symptoms, and rosacea doesn't bother them. They may enjoy perfectly healthy normal lives without any effect from this benign skin condition. Some patients really like the pink glow to their cheeks and find it gives them a pleasant color without having to use blush. They may not even know they have rosacea. They usually do not want to use any treatment.
Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all teenagers during puberty -- the only exception being members of a few primitive Neolithic tribes living in isolation. It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.
