Understanding Acne: Causes, Treatments & When to See a Dermatologist
Jan 20, 2026
Acne is one of the most common skin conditions in the United States, affecting people of all ages—not just teenagers. At Redwood Empire Dermatology, we diagnose and treat acne every day across our Healdsburg and Santa Rosa offices, helping patients regain confidence and achieve clearer, healthier skin.
Whether you're dealing with occasional breakouts or persistent cystic acne, understanding the cause of your acne is the first step toward effective treatment.
What Causes Acne?
Acne forms when pores become blocked by a combination of:
✔ Excess oil production
Hormonal changes—especially during puberty, pregnancy, and perimenopause—can stimulate oil glands.
✔ Dead skin cell buildup
Skin naturally sheds cells, but when they accumulate inside pores, they create blockages.
✔ Bacteria (C. acnes)
Once a pore is clogged, bacteria can multiply and lead to inflammation.
✔ Hormonal fluctuations
Androgens can increase oil production and worsen breakouts. Adults—especially women—commonly experience hormonal acne around the jawline and chin.
✔ Genetics
Acne often runs in families.
Environmental factors like stress, heavy cosmetics, occlusive clothing, and certain hair products can also contribute.
Types of Acne
Acne isn’t one-size-fits-all. Different types require different treatments.
These occur when pores are clogged with oil and skin cells.
Red bumps or pimples with or without visible pus.
Painful, deep acne lesions that often lead to scarring if untreated.
If you're unsure which type you have, our dermatology providers can help evaluate your skin and tailor a treatment plan.
