Tea Tree Oil (topical)

Moderate safety

Evidence

Evidence Score5/10

Studies: 6

Meta-analyses: 0

Dosage & timing

Dosage:

Topical cosmetic only. Acne trials used a 5% tea tree oil gel applied to affected areas (typically twice daily). Avoid undiluted (100%) application, which is more irritating and sensitizing. Patch-test first, and use fresh, properly stored product (oxidized oil raises allergy risk). There is no oral or systemic dose — it is not ingested (and tea tree oil is toxic if swallowed). This library does not provide an ingestion protocol.

Best Time:

Any time

Can take on empty stomach

Form:

5% tea tree oil gel (the trial-tested strength)
