My sister’s lips got completely black after using this product. This product looks very good when you apply it on your black, after using it for a month or later you have noticed that your lips are getting black. If you use this product regularly then your lips got black in just 20 days. After that, me and my sister went to the skin doctor to remove the blackness of completely, but the doctor said that we will remove the blackness but not completely. Because this product damages my sister’s lips completely. I also complained about this thing to their company but they just couldn’t cooperate with me. This product really damaged your lips.
