Why a Long Philtrum Makes the Face Look Older — Facial Proportions & Smile Dynamics
- An elongated philtrum stretches the midface, rolls the upper lip inward, and makes the lower third of the face look older.
- Surgical planning evaluates the 1:2 philtrum-to-chin ratio, upper incisor show at rest, and dynamic smile excursion together.
- Anchoring the deep orbicularis muscle layer along a concealed subnasale bullhorn line prevents nostril widening and scar stretching.
"I haven't lost weight, so why do I suddenly look older in photos?"
"My expression looks somehow gloomy and heavy even when I'm relaxed."
The unexpected culprit behind these common concerns is the length of the philtrum (the vertical groove between the base of the nose and the upper lip). Today, from a plastic surgeon's perspective, I will explain why philtrum length has such a decisive impact on facial youthfulness.
1. Ideal Vertical Facial Proportions: 1 : 1 : 0.85–0.9
Classically, balanced vertical facial thirds follow a ratio of Forehead : Midface : Lower Face = 1 : 1 : 0.85–0.9. While a long chin can make the face look mature, an elongated midface ages the overall impression far more dramatically—and the decisive anatomical factor governing perceived midface length is the philtrum.
2. The 4 Classic Hallmarks That Age a Face
Consider the visual traits illustrators use when drawing an older character: (1) drooping outer eye corners, (2) bulging under-eye bags, (3) marionette lines, and (4) an elongated philtrum. Of all four, an elongated philtrum is often the most critical because it alters dynamic facial expression.
3. Why a Long Philtrum Is Critical: Upper Teeth Disappear When Smiling
When the philtrum elongates, the upper lip rolls inward and curtains over the upper teeth when speaking or smiling, exposing the lower teeth instead. Bright upper-tooth show is the hallmark of a vibrant, youthful smile; when hidden, the expression turns somber regardless of chronological age.
4. How AVA Approaches Philtrum Reduction: Concealed Incision & Dual-Plane Release
The biggest concern patients have about philtrum reduction is scarring beneath the nose. Simply cutting a strip of skin and stitching it under tension risks both a visible scar and gradual re-lengthening. At AVA Plastic Surgery, we address this through:
- Shadow-concealed incision geometry tucked inside the natural nasal sill contour
- Dual-plane tension release so deep muscular anchoring bears the load rather than the skin edge
- Minimized relapse while restoring natural upper-tooth show

Frequently Asked Clinical Questions (FAQ)
Q. What is the ideal facial proportion between the philtrum and the chin?
In balanced lower-face aesthetics, the vertical length from the subnasale (base of the nose) to the upper lip border is approximately half the distance from the lower lip to the tip of the chin (a 1:2 ratio).
Q. How do you prevent nostril distortion or a wide scar after a bullhorn lip lift?
By placing the incision strictly within the natural shadow crease at the base of the nose and suspending the deep subcutaneous and muscle fascia to stable deep tissue so the skin edges heal tension-free.
Q. When are sutures removed after philtrum reduction in Seoul?
Fine sutures along the nasal base are removed on post-operative day 7, followed by scar-care guidance to help redness fade smoothly.
