Orange (Citrus sinensis) – Packed with vitamin C, collagen and citric acid, orange extracts offer many benefits to your skin. Orange extracts can reduce dark spots and sun damage while promoting moisture retention and fighting skin infections. The citric acid in oranges acts as a bleaching agent which can lighten the skin and reduce darkening caused by sun exposure. Orange peel is an effective cleanser because it purifies the pores, removing excess oil, dirt and dead skin cells and reducing the frequency of acne outbreaks. Oranges are native to southeast Asia, with varieties believed to have been cultivated for nearly 7000 years. The refreshing and invigorating aroma of oranges is due to the essential oils, which are popular in the worlds of phytotherapy, perfume and cosmetics.
