  • "Benzoyl Peroxide vs. Tea Tree Oil for Acne"

  • Acne remains one of the commonest diseases to afflict humanity.

  • If you do online surveys, tea tree oil appears to be

  • the second most commonly used topical treatment after benzoyl peroxide.

  • Though crowdsourcing may be a "novel research method

  • for evaluation of acne treatments,"

  • before getting too enamored with popular wisdom, you should know

  • that there's stuff like this circulating on the internet:

  • the facial application of urine as a home remedy for acne.

  • Urine therapy advocates cite historical use as proof of its therapeutic potential

  • as a free cure for many systemic diseases, apparently forgetting

  • all the godawful, crazy skeletons crowding the closets of medical history.

  • While recycling what the body intentionally removes

  • may seem counterintuitive to good health, what about Premarin?

  • The best argument this author could come up with for putting urine on your face is,

  • hey, women, after all, swallow pills made from pregnant horse pee.

  • I'm not exactly following the logic there.

  • Of course, there's drugs for acne;

  • there's always drugs, though along with drugs come drug side effects.

  • Antibiotics that suppress the bacteria that cause acne

  • are the standard treatment for acne, but are becoming less effective

  • presumably because of the emergence of antibiotic-resistant strains.

  • The prevalence of resistant strains has apparently grown rapidly,

  • such that antibiotics for acne are no longer recommended

  • just by themselves, with re-evaluations advised every six to eight weeks.

  • Well, the bacteria do seem to be susceptible

  • to tea tree oil in a petri dish,

  • but these kinds of studies were performed with free-floating bacteria,

  • whereas in pimples the bacteria form what's called a biofilm,

  • which makes them generally more difficult to eradicate.

  • The bacteria forms like a glue that plugs up the follicle,

  • so petri dish studies can only tell you so much.

  • Even if tea tree oil couldn't kill off the bugs, though,

  • it has been shown to suppress skin inflammation.

  • Like if you inflame people's skin with an allergen and then try to calm it down,

  • tea tree oil did a decent job compared to an over-the-counter ointment

  • or a moderate potency prescription steroid cream.

  • So potentially, tea tree oil could help with acne via an antibacterial mechanism

  • or from an anti-inflammatory standpoint,

  • but you don't know until you put it to the test.

  • A 20% tea tree oil gel applied twice a day and a beautiful drop in acne lesions

  • after one, two, three months. About 24 pimples down to about 11.

  • They conclude that the study showed that tea tree oil could significantly improve

  • mild-to-moderate acne, but who can tell me the study's fatal flaw?

  • Right, there was no control group.

  • How do we know they wouldn't have healed even faster without it?

  • In this systematic review of randomized clinical trials on tea tree oil,

  • their most striking finding is that they could hardly find any.

  • Given the widespread use of tea tree oil,

  • this is both disappointing and important to note.

  • But finally, a randomized, double-blind, placebo-controlled trial

  • of a 5% topical tea tree oil gel in mild-to-moderate acne.

  • After six weeks in the tea tree oil group,

  • a 40% drop in whiteheads and blackheads,

  • a 40% drop in red and tender acne bumps, and a 47% drop in pus-filled pimples,

  • compared to comparatively little change in the control group.

  • Overall, in terms of total lesion count,

  • the tea tree oil gel was 3.5 times more effective

  • than placebo, 3.5 times more effective than essentially doing nothing.

  • But most teens don't do nothing for their pimples.

  • How does tea tree oil compare to the gold standard, benzoyl peroxide?

  • We'll find out right now!

  • Benzoyl peroxide is by far the most popular over-the-counter acne therapy,

  • despite its side effects.

  • It can be irritating, causing redness, dryness, peeling, stinging, burning.

  • However, the prescription option,

  • the long-term use of topical or oral antibiotics,

  • is discouraged due to the development and spread of antibiotic resistance.

  • As a result, attention has turned to non- antibiotic products such as tea tree oil.

  • The benzoyl peroxide did cause more side effects

  • dryness, itching, stinging, redness, burningbut it worked better too,

  • cutting the number of inflamed pimples by two-thirds within three months

  • versus only by half in the tea tree oil group,

  • though the most recent study found them to be more comparable.

  • Putting all the studies together,

  • and tea tree oil products not only beat out placebo,

  • but approximate more standard regimens like benzoyl peroxide

  • or topical antibiotics, suggesting tea tree oil products

  • may be an appropriate option for treating mild-to-moderate acne.
