CHANEL 'writes' the ultimate solution to address dark spots: A duo of pens developed specifically for day and night. For spot-on precision, the unique pen shape features a cooling ceramic applicator and flexible silicone neck with a convenient formula-release button. In addition to patent-pending Double Action TXC™ and complementary 2-Year Pearl Extract, each formula offers unique ingredients targeted to the specific time of day. For day, Geranium Extract addresses the effects of UV rays and pollution, while visibly diminishing the appearance of dark spots. For night, Alpinia Extract promotes skin’s natural renewal process for a brighter complexion and more even tone.
