There are many misconceptions about acne, but one thing is sure: it’s the bane of virtually every teenager. But it can last into the adult years, as well, particularly for women. Dr. Kronberg, Dermatologist in Houston, TX puts her 30 years of clinical dermatology experience to work helping her patients deal with their acne.
What Is Acne?
Clinically known as acne vulgaris, common acne is basically a function of the sebaceous glands located at the base of the hair follicles. These glands produce oil that keeps our hair and skin lubricated and moist. Acne forms when the sebaceous glands become clogged and the oil is trapped beneath the skin. An acne breakout is when these clogged pores become inflamed, appearing as occluded pores (whiteheads and blackheads), red bumps (pimples), pustules, or cysts.
Acne usually forms on the face, back, neck, shoulders, and chest.
What Causes Acne?
Despite its prevalence, the causes of acne aren’t completely understood. A combination of factors seems to be involved. Hormones play an important role. In teenagers, the rise in the male sex hormone androgen du
ring puberty causes the sebaceous glands to enlarge and produce more oil. This overproduction of oil can’t be distributed out of the glands quickly enough and some of them clog. In these glands, the p.acnes bacteria that are common now begin to multiply. This causes inflammation, which leads to a breakout. How this progresses varies between people — in some, elevated sebum levels might cause a lone pimple or two; in others, it can be a full outbreak.
Some people seem to be more prone to acne development, and this may have a genetic compon
ent. For adult women, hormone fluctuations during pregnancy or when taking certain birth control pills can cause acne breakouts. Acne can be a side effect of some medications. There is even a different form of acne, known as acne mechanica, that comes from the friction and heat generated from sports helmets.
What Doesn’t Cause Acne?
Acne has had more than its share of misconceptions. People long believed that eating chocolate or greasy foods directly led to breakouts. Research has since completely debunked that theory.
Another cause was thought to be personal hygiene. But no relationship between dirty skin and acne has been proven.
At one time, the thought was to dry out the facial skin as much as possible with harsh cleansers and scrubs. This would, in theory, remove the oil and open the pores. Actually, this leads to increased skin irritation and can exacerbate acne.
How Common Is Acne and Who Gets It?
This isn’t news, but acne is the most common skin disorder of teenagers, affecting roughly 85 percent of teens as some point between the ages of 13 and 20. This is obviously a result of the raging hormones of puberty.
In adults, women are more likely to have mild to moderate forms of acne into their 30s and sometimes beyond.
Types of Acne
Acne vulgaris is the medical term for common acne, with the presence of blackheads, whiteheads, and other types of pimples on the skin. Often the type of breakout is how acne is categorized.
- Whiteheads — A comedo is a basic acne lesion, a hair follicle that has become clogged with oil and dead skin cells. If the comedone is closed at the surface skin, it forms a whitehead.
- Blackheads — These are comedones that are open at the surface of the skin. They are filled with excess oil and dead skin cells. People think it is dirt that turns these lesions black, but it isn’t. It is simply the irregular reflection of light coming from the clogged follicles.
- Papules — If the comedones become inflamed they form small red or pink bumps on the skin. These are papules, and they may be sensitive to the touch.
- Pustules — These resemble whiteheads with a red ring around the bump.
- Nodules — Nodules develop deep within the skin and develop into a large, inflamed bump that feels firm to the touch. They are often painful.
- Cysts — Cystic acne is the most severe form, and it leads to permanent acne scarring. Cysts are large, pus-filled lesions that resemble boils.
Relationship Between Hormones and Acne?
Hormones are the main driver of acne. Androgen is a staple of puberty in both girls and boys. This male sex hormone triggers excess oil production in the sebaceous glands, leading to those glands clogging and becoming inflamed. Hormonal changes related to pregnancy and in birth control pills can cause the same increase in sebum production in adult women.
How Does Dr. Kronberg Treat Acne?
Dr. Kronberg employs a variety of tools for treating her patients’ acne. These range from oral medications and topical products to laser treatments, Intense Pulsed Light, and LED light. Different treatments are effective for different patients, so she may need to try a treatment strategy and then adjust or change it if she’s not getting the hoped for results.
“I love seeing Dr. Kronberg. I am new to her and she has made my acne of many years go away. I have been to many Dermatologists and this is the first time my face is clear.She is patient and explains everything. It’s as though you are her only patient. I am very pleased”. – Helen H.
- Retinoids — These drugs are derived from vitamin A and include tretinoin, adapalene, and tazarotene. They come in cream, gel, and lotion forms. They work by preventing plugging of the hair follicles.
- Antibiotics — Antibiotics work by killing excess skin bacteria and reducing inflammation. They are usually combined with a retinoid and benzoyl peroxide (to reduce the risk of developing antibiotic resistance.)
- Salicylic acid and azelaic acid — Salicylic acid helps prevent hair follicle clogging and azelaic acid has antibacterial properties.
- Dapsone — This is used with inflammatory acne, especially in adult women.
- Antibiotics — Oral antibiotics are used to reduce bacteria in the sebaceous glands and to fight inflammation. These cannot be used for long periods as resistance can develop.
- Combined oral contraceptives — Combined oral contraceptives are approved by the FDA for treatment of acne. They combine estrogen and progestin.
- Anti-androgen agents — The drug spironolactone can be used for adolescent girls and adult women if oral antibiotics aren’t helping. This drug works by blocking the effect of androgen hormones on the sebaceous glands.
- Isotretinoin — This is a powerful drug that is very effective in cases of acne that don’t respond to other treatments. The brand name Accutane is the most well known of these drugs, but it is no longer on the market.
Other Acne Treatments
Beyond medications, Dr. Kronberg may use laser and light therapies and chemical peels to treat acne. Sometimes these are combined with medications.
- Lasers and photodynamic therapy — A variety of light therapies can be effective in treating acne. In some cases, the light is applied with an activation chemical known as Levulan. The goal of these treatments is to kill the bacteria that are multiplying in the clogged hair follicles, causing inflammation and breakouts. Omnilux is an LED light treatment. Fotofacials use Intense Pulsed Light. Regenlite is a pulsed dye laser.
- Chemical peels — Chemical peels use a peeling agent, usually salicylic acid, glycolic acid, or retinoic acid to remove some of the surface skin. These can improve clogged hair follicles and remove some surface bacteria, but their effects are not long lasting.
- Steroid injections — With cystic acne, Dr. Kronberg may choose to inject a corticosteroid directly into the lesion. This can rapidly shrink the lesion and decrease pain.
