In short. What is looked at with the face at rest, what changes when the brow is raised, how brow height is recorded, and what each finding changes about the options.
Key points
- How much of the line is movement, and where the brow sits when the muscle is quiet, are separate findings, and neither replaces the other.
- A plan that addresses only the first can leave the second looking worse than it started, and that outcome is predictable from the examination.
The consultation for forehead lines is short, and almost all of what it produces comes from watching the face do two things: nothing, and then something. What follows describes what is looked for and what each finding changes. It does not recommend a treatment, because assessment and treatment are separate decisions.
The resting face, in a known light
The first observation is made with the face relaxed and the light coming from in front rather than from above. A line visible now has a component in the skin itself; a line that has gone at rest is movement only. This one comparison decides whether a muscle rung on its own can produce what the patient is hoping for.
Then the same face in movement
The patient is asked to raise the brows, to look up without moving the head, and to squint. The depth of the folds at full contraction, how many there are, and whether they are even across the forehead are noted. A forehead where one side pulls harder than the other is common, and it changes the plan rather than the diagnosis.
Where the brow sits, and what holds it
The position of the brow relative to the eye is recorded at rest, and again with the frontalis relaxed, either by asking the patient to let the forehead go or by holding the brow lightly while they frown. If the brow sits lower once the muscle stops working, the lines have been partly the price of a raised brow. That finding most often changes a plan.
Two findings, recorded separately
How much of the line is movement, and where the brow sits when the muscle is quiet, are separate findings, and neither replaces the other. A plan that addresses only the first can leave the second looking worse than it started, and that outcome is predictable from the examination.
The skin, the lid and the history
Skin thickness, dryness and sun damage are recorded, because they decide whether a skin rung belongs in the plan. The upper lid is examined and vision is discussed, because a muscle being used to see is used more than it needs to be. The history covers how long the lines have been there, what has been used on the skin, and any previous treatment to the upper face.
What the assessment should also rule out
- A brow that has dropped on one side only, or that can no longer be lifted on one side.
- A lump or swelling over the brow or upper forehead that was not there before.
- A spot that bleeds, crusts or has failed to heal, which needs a diagnosis rather than an opinion.
Why the folds run across is set out in why forehead lines form horizontal. The finding that most often changes a plan has its own guide in forehead lines and a heavy brow, and the line that has settled into the skin in when lines are etched rather than moving.
Frequently asked questions
Why does the examination start with my face doing nothing?
Because the resting face is the only state in which the skin can be seen on its own. Once the brow is raised the muscle is folding the skin, and the observer can no longer tell how much of the line is a crease in the tissue. Asking the patient to relax first gives that measurement, and everything afterwards is read against it.
What does it mean if my brows are uneven?
It usually means that one frontalis pulls harder than the other, which is common and harmless in itself. It matters because it changes where treatment is placed: a plan that treats both sides equally can leave the asymmetry more obvious than it was. It is better to know about it before treatment than to discover it after.
Does this article tell me which treatment to have?
No, and deliberately so. Assessment and treatment are separate decisions, and mixing them is how people end up treated for a component they do not have. What the examination produces is a description of your forehead: how much movement, how much skin, where the brow sits, and which of those is doing the most work in your case.
Risks & Limitations
- Relaxing the frontalis also lowers the brow, because the same contraction holds it up. How far it drops is judged before treatment, not discovered afterwards.
- A line that is still visible with the face at rest has a component in the skin, and no treatment directed at the muscle removes it.
- The relaxing effect wears off and the treatment is repeated, so the appointments do not end on their own.
- Resurfacing brings real downtime and a risk of pigment change that is higher in skin which tans easily.
- Volume placed into a crease rather than into a hollow can show as a ridge under light, and it does not remove the line.
When to Seek Care
- A brow that has dropped on one side only, or that can no longer be lifted on one side.
- A forehead that has stopped moving, or sudden weakness, difficulty speaking or swallowing, or double vision, which need emergency care rather than a routine appointment.
- A new lump or swelling over the brow or the upper forehead, or a spot that bleeds, crusts or fails to heal.
- Severe pain, or skin that turns white, dusky or mottled, after an injection in this area. Any change in vision afterwards is an emergency.
- A drooping upper lid, or an eye that becomes persistently dry or irritated, after treatment to the forehead.
