Acne

Often at the completion of a skin check or other dermatologic visit, a patient will say, “Before you leave, I just want to ask you one thing about my 12 (13,14…) year old.” Parents are naturally concerned about the adolescent transformation of their young teen. Part of this transformation for most children, is that disturbing rite of passage, acne. Blackheads, whiteheads and pimples begin to erupt.

Blackheads are commonly seen in adolescent acne.

For some there are subtle breakouts over the T-zone (chin, nose and forehead) only. For others the changes are more dramatic, and can lead to scarring of the face, chest and back. If the acne lesions are painful, large, or resolve leaving behind a pitted or discolored area, or if there is extensive involvement of the face, chest or back, it is time to see the doctor. Some pediatricians are adept at treating acne, particularly of the mild to moderate variety. A dermatologist, however, can provide a full array of treatment for mild acne all the way to severe scarring acne. If acne is mild, as it is for most teens, a trial of over-the counter acne medication is in order.

The least irritating treatment is a wash that contains salicylic acid (such as Neutrogena Oil-Free Wash). This helps unclog pores which prevents the formation of pimples and comedones (black heads and white heads). Start the wash and wait east 1 week before adding a second treatment to assess if your child is allergic to the active ingredient, salicylic acid.

Week 2 add a cream containing benzoyl peroxide (BP). BP kills bacteria and decreases inflammation in the follicle where acne pimples form. Creams that contain 10% BP are very harsh and irritating and work no better than creams containing a lower percentage. Try to find a product containing 2.5% to 5% benzoyl peroxide.  Apply a small amount of BP product to the entire acne prone area, not just active pimples, once per day (try Neutrogena Rapid Clear Daily Mask). Keep in mind that BP can bleach clothing and bedding, so white pillow cases and towels are recommended. About 5% of people are allergic to or irritated by benzoyl peroxide, so if the skin becomes red, itchy or swollen, stop the cream immediately. Pregnant women should not use any over-the-counter or prescription acne medication without first consulting their doctor.

It takes a full 2 months to see the improvement from any acne treatment, even the strongest oral therapy. So patience is the key here.  If the acne is more substantial, or if  at the 2 month point mild acne is still present, retinoids are the next step. These topical medications include gels and creams that are made of Vitamin A derivatives to unclog the follicles. Recently one of best prescription retinoids was approved for over-the-counter sale.  Differin 0.1% gel can be purchased inexpensively at your local pharmacy.  Adapalene 0.1% cream, and 0.3% gel, tretinoin (Retin-A) and tazarotene (Tazorac) still require prescriptions.  To avoid irritation, start your retinoid every other night for a week or two, then increase to nightly as tolerated.  Use an oil free moisturizer on top of the retinoid to minimize dryness.

Once the over-the counter medications have been exhausted, prescription topical and  oral medications may be necessary for persistent acne. Oral options include antibiotics, hormonal medications for women (such as birth control pills) and finally the oral Vitamin A derivative isotretinoin (Accutane). The risks and benefits of all of these options should be reviewed with a knowledgeable dermatologist.

Acne is largely genetic, and is also affected by hormones, hence its appearance and persistence throughout puberty, and sadly reappearance during early menopause.  Though it may be tempting to tell your teen that french fries and donuts cause their acne, that isn’t the case. High dairy intake, particularly skim milk, has been associated with acne, but is not the primary cause.  Some moisturizing creams and sunscreens can make acne worse. Make sure all products used on the skin have the words “non-comedogenic” or “oil free” on their label. Moisturizers are often necessary to counteract the dryness from the acne treatment medications. Some non-comedogenic choices are Neutrogena Gel Boost and Cerave moisturizers.

Although facials and glycolic peels may be helpful in some patients, they do not replace the need for evaluation and the prescription of appropriate medications. Likewise the Smoothbeam® Laser is used in our office for acne resistant to medications, or patients that are unable to tolerate oral medications, as well as for acne scarring. However, we recommend this laser only after optimal treatment with prescription medication is instituted.

Don’t wait until scarring sets in to have your child’s acne treated. Acne treatment is a process. It may take months to come up with the best treatment while minimizing the potential side effects of acne medication.
