What is white roll lips?

White roll lips are a part of the upper and lower lips and are characterized by a thin, white line that runs along the edge of the lip where the skin meets the mucous membrane. This line is also known as the vermillion border. White roll lips are considered a desirable feature of the lips in cosmetic surgeries and makeup application as they enhance the definition and contour of the lips. However, the absence or loss of this white roll can indicate certain health conditions such as anemia or vitamin deficiencies. Proper lip care, including regular hydration and protection from sun damage, can help maintain healthy white roll lips.
