The lines you notice
Creases that stay when you look straight ahead
Horizontal neck lines aren't only an age-related change. Some have been there since you were young; others become more noticeable over time.
The practical details
Necklace-line filler at a glance
The treatment targets horizontal grooves, with the product and amount chosen for the depth of the lines and the skin covering them.
The result
Lines that stand out less across your neck
Filler can make a horizontal groove shallower, giving a smoother transition between the crease and the skin either side of it.
You may want one especially deep crease softened, or a more even appearance across several lines. Dr Alex will discuss how much smoothing is realistic and which grooves are likely to respond best.
Your neck will still fold as you move. A line that appears when you look down isn't the same as a deep groove that remains when your head is upright; the treatment focuses on those persistent indentations.

Would it suit you?
Are you treating lines or loose skin?
A distinct horizontal indentation is a different concern from a generally crepey neck, loose skin or vertical muscle bands.
A different concern
Filling a line won't lift a loose neck
Filler doesn't remove excess skin or relax prominent vertical neck bands. Significant sagging may need a surgical opinion, while muscle bands or more general skin-quality changes have other treatment options. Adding more gel to a crease won't correct those separate problems.
How it works
Supporting the skin along the groove
Small amounts of hyaluronic acid gel are placed to reduce the indentation of a horizontal neck line.
As the groove becomes shallower, the change in level between the line and surrounding skin is less obvious. That can soften both the crease and the shadow it creates.
The neck has thin skin and moves frequently, so the filler needs to suit that tissue. Dr Alex chooses the product and amount after assessing the lines, rather than treating every groove to the same depth of correction.
This is direct support from a gel. It doesn't switch off the muscles or produce the lift of a neck operation.
Your appointment
Show Dr Alex the lines you want to soften
He'll examine your neck at rest and as it moves, so the recommendation reflects how it looks in everyday life.

Why Dr Alex
Why choose Dr Alex for necklace-line filler?
Dr Alex teaches doctors, dentists and nurses across several dermal filler ranges. He is currently a trainer for Evolus's Estyme filler range and has helped launch Estyme and Aliaxin LV in the UK.
For neck lines, product choice and the amount of correction need to suit thin, mobile skin. He'll assess the groove itself as well as how the surrounding skin folds, so the recommendation is aimed at a smoother appearance in normal movement.
If you've had injections in the neck before, he'll check what was used and how the area has responded. The next treatment should build on that assessment, rather than simply repeat what was done last time.

Side effects and suitability
What should you know about recovery and risks?
Injection marks, bruising, tenderness and swelling can be visible after treatment. Small raised areas may show more readily through the thin skin of the neck.
Possible side effects
Unevenness, persistent lumps or a bluish tint can occur if filler shows through the skin. Infection and delayed inflammatory reactions are also possible. Any lump that persists or becomes painful needs assessment.
A blocked blood vessel is an uncommon but serious complication that can damage the skin.
When to seek urgent help
Contact SONÜ urgently for unusual or increasing pain, or skin turning pale, grey, dusky or mottled. Seek urgent medical care if you cannot reach the clinic. Rapid neck or throat swelling, or difficulty breathing or swallowing, requires emergency help - call 999.
When treatment may need to wait
Active infection, broken skin or an inflamed rash in the area needs assessment first. Tell Dr Alex about allergies, medicines, previous filler reactions, pregnancy or breastfeeding and any relevant medical condition or neck surgery.
You can take time to consider the recommendation before deciding on treatment.
