Hollow temples: why they form and what fills them

Seen from the front, the area just outside the end of the brow can sink in and make the upper face look narrow and drawn. It gets less attention than hollow cheeks, but it accounts for a good part of that “why do I look so tired lately” feeling.

The short answer

Hollow temples come from age, weight loss and the face you were born with. For filling them, there are randomised trials of hyaluronic acid filler and PLLA. In the hyaluronic acid trial, 80.4% improved by one grade or more at three months (13.5% untreated) and it lasted over a year. In a 174-person PLLA trial, 96.5% improved at six months (0%). Large blood vessels run through the temple, so setting the depth and position matters. At Miso Clinic, 4F Bombom Building, 125 Dongdeok-ro, Jung-gu, Daegu (Exit 1, Kyungpook Nat'l Univ. Hospital Station), +82-53-428-2700, I consider dissolvable hyaluronic acid filler first for the temples too.

Why do temples hollow?

The temple is bone covered by a thin layer of muscle and fat. With age, that fat and muscle shrink, and big weight loss shows it sooner. People with long faces and wide cheekbones can look hollow there even when young.

When the temple hollows, the end of the brow loses its support and looks lower, and the cheekbones stand out by contrast. The upper face narrows and the whole impression sharpens.

I couldn't find a study splitting the causes of hollow temples by percentage. In clinic, age and weight change together are common.

How well does temple filler work, and how long does it last?

Studies filling hollow temples
MaterialStudyResultCaution
Hyaluronic acidRandomised 2:1 against no treatment80.4% vs 13.5% at 3 months, held to 13 monthsManufacturer-employed authors
PLLA174 people randomised against no treatment96.5% vs 0% at 6 months, followed 12 monthsInjected over 2–3 sessions
Hyaluronic acid20 people, 12 monthsImproved at every visit, side effects resolved within 2 weeksNo control group, single centre

All three studies showed fairly clear effects. The numbers belong to that product and that technique, though. I don't transfer them to other products.

Hyaluronic acid fills straight away and can be dissolved, so it's an easier first step. PLLA fills gradually over months, needs several sessions and can't be dissolved.

Is temple filler risky?

Large blood vessels run through both the shallow and deep layers of the temple. So I decide which layer to use and whether to use a needle or a blunt cannula before starting. I prefer to inject in small amounts over more than one pass rather than all at once.

Aching in the temple when chewing and swelling are common afterwards and usually settle within a few days to two weeks. If the skin turns white or blotchy during or right after treatment, or your vision changes, tell us immediately.

Can Juvelook or other boosters fill the temples?

Collagen-stimulating boosters are sometimes used in the temples, and the PLLA trial belongs to that family. I didn't find a randomised trial in the temples for other materials such as Juvelook in this search.

For deep hollows I shape with hyaluronic acid first, and if thin skin leaves the surface uneven, I consider a booster on top.

Can massage or exercise fill the temples?

I couldn't find research showing massage or chewing exercises fill the temples. You may hear that building the chewing muscles plumps them, but I couldn't find evidence for that either.

A small study found the temple muscle thickened after jaw Botox, while another found no such change. If you're having jaw Botox, I look at the temples too.

Hollow temples FAQ

How much filler goes into the temples?

It depends on how hollow they are and how wide your face is. I'd rather inject in stages and review at two weeks than fill everything at once.

My temples ache when I chew after filler.

Filler sits over the temple muscle, so chewing can ache for a few days. If it gets worse or the skin changes colour, contact us right away.

Will filling only the temples make a difference?

Many people look softer once the end of the brow has support. If the cheeks are hollow too, though, temples alone change less.
