There aren't many products I've repurchased for over 15 years, but the Body Shop's Tea Tree Mask is one of them. It was the first 'beauty treatment' I ever bought - in middle school - when lying in the bath with a towel turban, green mud drying on my face and two cucumber slices covering my eyes seemed the heights of sophistication. I now use the tea tree mask as a morning cleanser, especially in hot weather. A thin layer applied all over the face then rinsed with warm water or buffed off with soft cloth is a perfect gentle mattifying cleanse that leave skin feeling extra polished and so, so clean.
