My Bridge Isn't Low, but I Was Recommended 4mm Silicone — Why Numbers Alone Cannot Decide
2024. 10. 15.
If you were recommended 4mm silicone without having a low bridge — rather than gender averages, the relationship between skin, bone structure, and the glabella-to-bridge balance is reviewed together. Why height cannot be judged by the number alone.

Key points
- Silicone height is not decided by whether the bridge is low alone — the height difference between the brow bone toward the glabella and the glabella between the eyes is reviewed together.
- Silicone height is not set by a single gender average — skin thickness, bone structure, and the glabella-to-bridge relationship are considered together.
- Without seeing the patient directly, it is hard to say with certainty whether 4mm is appropriate — one option is to preview the result through virtual surgery simulation.
"I had a consultation and was told my bridge is not low, but not high either. My brow bone is developed but the glabella between my eyes is sunken, making the bridge look low, so 4mm silicone was recommended. From what I found, 4mm seems to be for people with low bridges — won't it become too high and obvious?"
A question that came into KOWON Plastic Surgery. Judging by the number alone, 4mm looks large — but unless the conditions that produced that figure are visible too, it is hard to judge.
01
Is 4mm silicone a figure used only for low bridges?
It is hard to divide it that way. 4mm is not a figure used only for low bridges — but it also cannot be generalized that 3–4mm is appropriate simply because the patient is male.
02
Then what determines the height?
The silicone height is set according to the condition. In a situation like the one described — developed brow bone but a sunken glabella making the bridge look low — what needs checking is not only the height of the bridge itself.
| What is checked | Why |
|---|---|
| How much the brow bone toward the glabella protrudes | It affects the impression that the bridge looks low |
| How low the glabella between the eyes sits relative to the brow bone | The same height can look different in degree |
Without checking these parts directly, it is difficult to answer with certainty whether 4mm is appropriate. How bridge height connects with facial impression in real cases can be seen in before-and-after photos.
03
Is there a way to preview whether it will look obvious?
If the worry is significant, checking what 4mm silicone would look like through virtual surgery simulation can help. Confirming how it would look applied to your current face is closer to a real judgment than imagining from a number alone.
04
Summary — look at facial conditions before the figure
Silicone height is hard to call large or small from the number alone. Depending on how much the brow bone protrudes toward the glabella, how low the glabella sits relative to it, and whether skin and soft tissue can cover the implant without strain, the same height can look different.
If you want to see how the recommended figure would apply to your face, it can be checked together with virtual simulation in a 1:1 video consultation.
