4-Terpineol
Acne Fighter
Some ingredients target acne through different mechanisms: killing bacteria, unclogging pores, or reducing oil production. They can support clearer skin over time, but consistency and patience are key - especially since everyone's skin responds differently. For severe or persistent acne, combine with professional dermatological care.
Explained
4-Terpineol is the main component of tea tree oil.
This ingredient is the reason tea tree oil has most of its reputation. Research points to a broad range of biological activity including antimicrobial, antioxidant, and anti-inflammatory effects.
Studies show it can significantly block the pathway involved in skin inflammation. It has also been shown to work against acne-causing bacteria, fungi, and even some viruses (and seems to be more effective on its own rather than part of tea tree oil).
Overall, this botanical extract is well-researched and skin-friendly.
