Is this safe to use for lips and how long does the color last on the lips.

safe- yes!! it has nourishing ingredients like squalane, peony extract, and acai fruit oil, making it completely non-toxic and safe. lasting: lasts 2-3hrs on the lips. While it boasts all-day wear on the cheeks, talking, drinking, and natural lip oils will break down a liquid blush formula much faster. hope this helps!
