It is a subjective choice or we can say personal preference. Everyone has an ideal lip shape and size. Some have thin lips, some have fuller lips and so on. Some have a cupid’s bow and some have heart-shaped lips. What you have is your ideal shape and is as per your features. As per science, most attractive lips have an upper-to-lower lip ratio of 1:2, which means a thin upper and fuller lower lip. But some people feel more attractive lips with 1:1, thin upper and lower lips. However, some people love lips with a cupid’s bow in which they have a cupid’s bow on their upper lips and lower fuller lips.

People have different lip shapes, which look beautiful in them, including full lips, thin lips, heavy upper lips, wide lips, round lips, heavy lower lips, heart-shaped lips, downward-turned lips and many more. Be happy with what you have and accept that you are beautiful in yourself.
