Biopark Tea Tree Hydrosol is derived through steam distilling tea tree leaves. It has a very fresh, clean, herbal, slightly medicinal smell, but much milder than the essential oil. It's beneficial for skin that is particularly oily, acne-prone or other problematic concerns. This hydrosol can be used as a deodorant spray for underarms or feet and serves as a wonderful refreshing effect in a foot bath. Doubles as a mouthwash to fight bad breath.
