Acne Q & A

What is acne?

Acne is a common skin condition that develops when your pores or hair follicles become clogged with excess facial oil — known as sebum — and dry, dead skin cells. These clogs cause whiteheads and blackheads to develop. When bacteria are trapped inside a pore with the sebum, they can produce an infection, inflaming your skin and creating a red pimple, pustule, or cyst.

While 50 million Americans suffer from acne every year, each person has a unique experience. You may only have a few pimples, or your skin may be covered in thick cystic acne that causes intense redness and swelling. If you previously had severe acne, you may have scarring that can make you feel as self-conscious about your skin as the acne did.

Whatever your experience, Dr. Aguirre offers personalized treatments to heal and clear your skin.


What causes acne?

Acne develops when your pores and hair follicles are clogged. While there are plenty of old wives’ tales about greasy food, chocolate, and poor hygiene causing acne, the primary causes of excess oil production and acne are:

  • Your hormones
  • Dairy products and whey proteins
  • Stress
  • Genetics


Your risk of acne is higher when you’re a teenager because of the hormonal fluctuations of puberty. However, acne can last well into adulthood. For example, many women experience breakouts at certain points in their menstrual cycles and can experience new onset acne near menopause.


How is acne treated?

Dr. Aguirre provides customized treatment plans to reduce your acne, improve your complexion, and remove scarring. She designs your plan specifically to meet your needs but may include any of the following treatments:

Lifestyle changes

Dr. Aguirre may suggest diet, exercise, and certain vitamin supplements to improve your overall health and wellness. She may also recommend getting more sleep and practicing some stress-relieving hobbies.

Topical treatments

She may prescribe medicated cleansers, toners, and topical creams to reduce the bacteria on your skin and control any infection or inflammation. Additionally, she offers chemical peels, light therapy, and other procedures to control acne.


If your acne is severe and doesn’t respond to topical treatments, Dr. Aguirre can prescribe medicines like Accutane® to reduce your acne.


In rare, extremely severe cases of acne, Dr. Aguirre can suggest surgery to remove acne and chronically infected hair follicles.

Scar treatment

If your skin is marked by acne scarring, Dr. Aguirre offers a variety of skin revitalization treatments like chemical peels, microneedling,  dermal fillers, fractional resurfacing, and photofacials to improve your complexion.
