A
What is the most effective treatment for forehead lines?
Horizontal forehead lines are mainly caused by the frontalis muscle lifting the brows. Botulinum toxin such as Xeomin is the standard first treatment: it relaxes the muscle, with results appearing in 3–7 days and lasting around 3–4 months. Lines that remain at rest may also need a soft hyaluronic acid filler or skin booster. Doses must be balanced carefully to avoid a heavy or dropped brow, and results vary.

Understanding forehead lines
Lines written by expression
Forehead lines are horizontal creases formed by the frontalis muscle, which lifts the eyebrows when we are surprised, concentrating or compensating for heavy eyelids. At first they appear only with movement; over time, as collagen thins, they can remain visible at rest.
They often appear alongside frown lines between the brows. Where the forehead is flat or slightly hollow, shaping with forehead fillers may be discussed separately.
Signs you may benefit
- Horizontal lines when raising the eyebrows
- Lines still visible with a relaxed face
- Make-up settling into forehead creases
- A tired or worried look in photos
- Habitual brow lifting to open the eyes
If you lift your brows to compensate for heavy eyelids, relaxing the forehead too much can make lids feel heavier — our doctors assess this before dosing.
Our approach
Balanced forehead smoothing
Treatment depends on whether your lines are dynamic, static or both, and on your brow shape and eyelid position.
Soft HA filler
A fine, flexible filler such as Belotero can be placed in etched lines that remain at rest.
Skinvive & boosters
Hydrating micro-droplets improve skin quality and fine creasing across the forehead.
Rejuran
Polynucleotide injections support thinner skin and elasticity over a course of sessions.
Thermage FLX
Radiofrequency tightening helps smooth the forehead and can give a subtle brow lift over several months.
What to expect
A smoother, relaxed forehead
Drag the handle to compare. Lines soften within days as the muscle relaxes, while natural brow movement is preserved.

Safety first
Possible side effects
Small injection marks, mild redness and occasional bruising are common and short-lived. A mild headache can occur on the first day. Uncommon effects include temporary brow heaviness, a raised outer brow or asymmetry, and very rarely eyelid drooping; these are temporary and some can be adjusted at the 2-week review. We reduce risk with conservative dosing, careful mapping of your brows and precise injection depth.
Toxin is not given during pregnancy or breastfeeding, or for people with certain neuromuscular conditions such as myasthenia gravis.

FAQ
Forehead Lines questions, answered
When will I see results?
Most patients notice softening in 3–7 days, with the full effect by about 2 weeks. Deeper static lines continue to improve over several months of regular treatment.
Will I look frozen?
Not when dosing is balanced. We aim to keep some movement so your expressions remain natural, and we can always add a little more at review rather than over-treat.
Can I fly after forehead Botox?
Yes, flying is generally fine after a few hours. Avoid lying flat, rubbing the area and intense exercise for the rest of the day.
Why do my brows feel heavy after treatment?
If the forehead muscle is relaxed too much in someone who uses it to lift the eyelids, brows can feel heavy. This is temporary; we plan doses carefully to avoid it.
Do I need filler for forehead lines?
Only if lines remain clearly visible at rest after the muscle is relaxed. A soft filler or skin booster can then smooth the remaining crease.
Can I treat other areas at the same time?
Yes. Many patients combine forehead lines with glabellar lines
and crow's feet
in one visit.
