A link has been suggested, but this report does not establish that either oil causes breast growth in boys. KOLO-TV revisited concerns about lavender and tea tree oil in skin products. The concern centers on Gynecomastia (Male Breast Tissue) in boys before puberty. This was a news report with expert comments and an industry response. It was not a new study testing the oils. Dr. Lamerson said breast tissue seemed to shrink within 3–4 months after stopping products described as having estrogen-like effects. That means effects like those of the hormone estrogen. But the excerpt gives no patient count or measured changes in breast tissue. It also gives no blood test results showing changes from either oil. Improvement after stopping a product does not, by itself, prove the product caused the change. The Australian tea tree oil industry group challenged the story. It said the suggested link began almost 20 years ago. It also said later research had failed to support it. That response comes from a group representing the industry, not an independent review. The supplied text does not include enough study details to settle the dispute. For BioSocial members, the key takeaway is uncertainty, not a proven cause. The report gives no clear exposure amount or way to identify who might be affected. A useful community discussion could compare product names, ingredients, use dates, and symptom timelines. Members with existing bloodwork can keep those numbers alongside their notes. These records can make experiences easier to compare without treating a shared pattern as proof. What have you noticed when comparing your skin-product history with symptom changes over time?
