Challenging Type 1A Lips.
This lip type with a central prominence (formed by three fused tubercles) and two separated lower tubercles is common, but often difficult to treat when the subcutaneous layer is tightly adherent to the muscle (on either side of the central prominence).
The Nonsurgical Lip Tubercle (NLT) technique helps by softening transitions between the tubercles while preserving the lip’s individual shape and natural function.
In total, 16 distinct lip types have been identified based on tubercle presentation (references in my comment👇)
