Typically, we each have two patterns or more, making lip prints as individual as fingerprints. The five common patterns are described as follows:
short vertical lines: these are almost vertical dots rather than lines;
long vertical lines: these lines extend at least halfway vertically down the lip;
rectangular lines: which may crisscross, looking like tic tac toe grids;
diamonds: the crisscross is diagonal, looking like diamonds;
branches: lines that don't conform to one direction.
Put some chapstick or lipstick on your lips and look at your patterns. Look at family members and see if you can find any similarities.
