# Tea Tree Oil

## Quick Summary

Tea Tree Oil is a skincare ingredient used for adult acne, oily skin routines. It is best judged by formula context, concentration, frequency, and skin tolerance rather than by the ingredient name alone.

## What It Is

Tea Tree Oil is used in leave-on or rinse-off cosmetic formulas depending on the product type. In SKB it is framed as a cosmetic skincare ingredient, not a prescription treatment or a diagnosis tool.

## Mechanism

Tea tree oil is a fragrant essential oil with terpene components that can show antimicrobial activity in lab contexts. On skin, the same volatile components can irritate or sensitize, so acne-use discussion must balance possible blemish support against dermatitis risk.

The mechanism is practical, not magical: vehicle, pH where relevant, dose, frequency, and the rest of the routine decide whether the ingredient feels helpful or irritating. Results should be judged gradually, and sensitive users should introduce it separately from other strong actives.
