Three-Area Botox: Forehead, Glabella and Crow's Feet Upper Face Guide
Short Answer
- "Three-area Botox" is a common way of describing upper face Botox for forehead lines, the glabella (frown lines) and crow's feet; it is not a product name or a standard protocol.
- These three areas work through connected muscles: the forehead muscle lifts the brows while the glabella and eye muscles pull them down. Because of this balance, the upper face is usually planned as a whole.
- Not every patient needs all three areas; the number of areas, dose distribution and suitability are decided individually at a physician examination.

Pre-Assessment
Clarify your upper face plan with an examination
This guide offers a frame for a safe decision. Which areas are needed, muscle balance, dose distribution and the follow-up plan should be addressed individually at a physician assessment.
What Is Three-Area Botox and Which Areas Does It Cover?
What clinicians call "upper face Botox" is usually searched for by patients as "three-area Botox". The phrase describes the three most established aesthetic uses of botulinum toxin: the horizontal lines across the forehead, the vertical frown lines between the brows, and the crow's feet that appear at the outer corner of the eyes when smiling. These three areas are anatomical neighbours and belong to the same system of expression muscles.
It is worth being clear from the start that this phrase is neither a product name nor a standard protocol applied to every patient in the same way. "Three areas" only describes where the treatment can be placed; how much each area is treated, and whether all three are really needed at all, varies from person to person. For the general working principle and safety frame of Botox, the What Is Botox? A Safe Treatment Guide is a good starting point.
Why Are the Three Areas Planned Together?
Treating the upper face as a whole is less an aesthetic preference than a functional reality. The frontalis muscle in the forehead is the only muscle that lifts the brows. The corrugator and procerus muscles between the brows, and the orbicularis oculi muscle that surrounds the eye, pull the brows down and inward. The resting position of the brow is the result of the balance these lifting and lowering muscles maintain throughout the day.
Intervening on one side of this balance alone can affect the result. When only the forehead is relaxed, the muscles that pull the brows down are left unopposed, and some patients notice heaviness or a dropped feeling in the brows; this picture is described in detail in the Heavy Brows After Botox guide. Conversely, when the centre of the forehead is relaxed but the outer part is left free, the tail of the brow can lift too far, producing the look known as Spock brow. Assessing the three areas together helps aim for a balanced result between these two extremes.
The second reason for planning together is visual coherence. Forehead lines softening while frown lines stay as they were, or the eye area being still while the forehead keeps creasing, can create a mismatched expression. An upper face treatment planned in the same session aims for a rested expression that still looks natural.
Planning Logic Area by Area
Forehead lines
The forehead is the area of the upper face that needs the most careful planning, because it directly determines brow position. Forehead height, where the brow sits at rest and whether there is excess eyelid skin all change the dose. In patients who constantly raise their brows to keep the eyelids open, the forehead dose is kept more conservative. The details of forehead planning are covered in the Turkish Forehead Botox: Dose, Brow Balance and Safe Planning guide.
Glabella (frown lines)
The area between the brows has the strongest muscle group of the three and sits at the centre of most upper face plans. Because frowning strength and muscle bulk differ markedly from person to person, the number of injection points and the dose distribution are set at the examination. The anatomy and safety topics of this area are described in detail in the Glabella Botox: Frown Lines Between the Brows guide.
Crow's feet
Crow's feet at the outer corner of the eyes become visible with smiling and squinting. The goal in this area is not to switch off the smile but to reduce the depth of the lines at the corner of the eye in a measured way. Because the area is close to the under-eye and cheekbone region, point selection needs care; the placement of the outer points is especially important for keeping the smile natural. The Under-Eye Botox Guide covers the neighbouring region and its limits.
The total dose used across the three areas is not calculated mechanically as the sum of the areas treated separately. The physician distributes the dose so that the balance between lifting and lowering muscles is preserved. Unit ranges per area seen online are only a general frame; the logic behind them is explained in Botox Units vs cc: How Dose and Dilution Actually Work, but they never replace a personal prescription.
How It Differs from "Full Face Botox" and the Limits of Package Thinking
Some clinics also use phrases such as "full face Botox" or "five-area Botox". These usually describe plans where areas such as bunny lines at the side of the nose, the chin, the corners of the mouth, the masseter or the neck are added to the upper face. There is an important difference between upper face and lower face treatments: because the lower face muscles play a direct role in speaking, chewing and smiling, the dose tolerance is narrower, and adding areas does not always mean a better result.
From a patient-safety point of view, the main caution concerns package thinking built around a number of areas. A figure such as "three areas" or "five areas" says nothing about the plan a person actually needs. A younger patient with strong glabella muscles alone may need a single area, while a patient with strong forehead muscles and pronounced crow's feet may need all three areas planned in balance. The right question is not "how many areas" but "which muscles, at what dose". For patients having treatment for the first time, the frame for a more conservative approach is described in the Baby Botox page.
Session Flow, Onset and Follow-Up
An upper face treatment is completed in a single session and is usually short. Before the application, the patient is asked to raise the brows, frown and smile with the eyes narrowed; the direction and strength of the muscles are assessed during these movements and the points are marked accordingly. Returning to daily life on the same day is usually possible; general advice for the first hours, such as not massaging the area, not bending forward and avoiding intense heat, applies.
The effect may not begin at the same pace in all three areas. The first change is often noticed earlier in the glabella and crow's feet, while the forehead can take a few more days; a more meaningful assessment is generally made around 10-14 days. This process is described day by day in the Botox Onset and Duration Timeline. The follow-up appointment is particularly important in the upper face, because the balance between the three areas can only be seen once the effect has fully settled. Brow-tail symmetry, the degree of forehead movement and the naturalness of the smile are reviewed together at this visit. When a small balancing touch is needed is covered in the Botox Touch-Up and the Two-Week Review guide.
Duration can also differ by area. In thin, highly active muscles such as those around the eyes the effect generally fades a little earlier, while in the glabella it may last longer. This difference means the treatment interval is planned around the upper face as a whole rather than a single area.
Safety and Side Effects
After upper face Botox, temporary redness, mild swelling or small bruises can be seen at the needle entry points; these mostly settle within a short time. Less common topics that deserve specific discussion in the upper face are brow drop, brow asymmetry and eyelid drooping. These are related to the product spreading beyond the targeted muscle or to the balance between muscles not being fully accounted for, and they are not permanent; the details are described in the Droopy Eyelid (Ptosis) After Botox guide.
Correct anatomical planning, appropriate dose distribution and following the aftercare advice all play a role in reducing these risks. Using an original product approved by TİTCK and CE — and, for products with FDA approval such as Botox, verified as FDA, TİTCK and CE approved — is a non-negotiable part of patient safety. Situations that may require postponing treatment, such as pregnancy, breastfeeding, a history of neuromuscular disease and certain medications, apply equally to all three areas and are asked about at the examination.
What a Physician Assessment Will Clarify
A decision about upper face Botox is not made by the number of areas or by example results seen online. In Dr. Hamza Gemici's editorial approach, the strength of the lifting and lowering muscles, the resting position of the brow, excess eyelid skin, facial asymmetry, previous procedures, medication use and realistic expectations are considered together. The purpose of this conversation is not to create an individualized treatment claim, but to help the patient make an informed decision about suitability, the areas that are actually needed and the follow-up plan.
- Pregnancy, breastfeeding, a history of neuromuscular disease and active skin infection are asked about as situations that may require postponement.
- Blood thinners, regular supplements, allergy history and recent aesthetic procedures are noted.
- Whether all three areas are really needed, the brow-position goal and how much forehead movement will be preserved are clarified with the patient.
Safe Preparation and Follow-Up
In botulinum toxin applications, quality is not limited to the moment of injection. Pre-appointment information sharing, transparency about product and practitioner, post-procedure care instructions and the follow-up time are all parts of the same safety frame. In the upper face, monitoring the balance between the three areas is added to this frame.
| Stage | Patient-side check | Why it matters |
|---|---|---|
| Pre-consultation | Which areas bother you and your brow-position expectations are shared openly. | The number of areas follows need rather than package thinking. |
| Application day | The product, injection-point plan and dose distribution between areas can be asked about. | Transparent communication supports patient safety. |
| First days | Advice on massage, bending forward, intense exercise and excessive heat is followed. | The chance of the product spreading beyond the target is reduced. |
| Follow-up | The effect is generally assessed around 10-14 days. | Brow symmetry, forehead movement and smile naturalness are reviewed together. |
Frequently Asked Questions
Which areas does three-area Botox cover?
It usually covers forehead lines, the glabella (frown lines between the brows) and the crow's feet at the outer corner of the eyes. Together these are called the upper face; which areas are actually needed is decided by an individual muscle analysis.
Do all three areas have to be treated in the same session?
No. The upper face is assessed as a whole in most patients, but one or two areas may be enough for some. The decision is based on muscle balance and individual need, not on the number of areas.
How soon does three-area Botox work and how long does it last?
The effect usually begins within a few days and is assessed more meaningfully around 10-14 days. Duration varies from person to person, and the forehead, glabella and crow's feet may not last equally long.
If I only treat my forehead, will my brows drop?
The forehead muscle is the only muscle that lifts the brows; relaxing the forehead alone can cause a feeling of heaviness in the brows in some patients. That is why the forehead is usually planned together with the glabella and the dose is kept balanced. Suitability is clarified at an examination.
