All types of acne — blackheads, whiteheads, pimples, and cysts — develop when pores in our skin become clogged. The culprit is sebum [see-bum], an oil in our skin. Our bodies make more sebum when our hormones surge. This is why teens get acne. This is why women often breakout before their periods. Since hormones fluctuate in the years leading up to menopause, many women in their 40s and 50s get acne.
Rosacea (ro-ZA-she-uh) is a chronic, inflammatory skin condition that affects adults. It causes redness in your face and produces small, red, pus-filled bumps or pustules.
Left untreated, rosacea tends to be progressive, which means it gets worse over time. However, in most people rosacea is cyclic. Rosacea signs and symptoms may flare up for a period of weeks to months, and then diminish before flaring up again. Besides acne, rosacea can be mistaken for other skin problems, such as a skin allergy or eczema.
