Functions
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Fragrance
Added for scent. Can be natural or synthetic. Common irritant and allergen — one of the top reasons people react to products.
Antimicrobial
Keeps your product from growing bacteria, mold, or yeast. Without these, that jar of cream becomes a petri dish in about a week.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.
Astringent
Tightens and contracts skin tissue, temporarily shrinking pores and reducing oiliness. That "clean, tight" feeling after toner.
Fights acne
Causing bacteria
Controls excess oil
Quells irritation
Traditional Use
Used for centuries by Aboriginal Australians to treat wounds and skin infections. Tea tree oil gained widespread popularity in Western skincare in the 1980s-1990s after scientific validation of its antimicrobial properties.
