Frown Line (11 Lines) Botox in Myeongdong, Seoul
The vertical ‘11 lines’ between the brows can make you look tired or cross when you are not. Frown line Botox is one of the most rewarding and best-studied areas to treat.
Quick answer
Frown line Botox relaxes the corrugator and procerus muscles between the brows that create the vertical ‘11 lines’. A standard treatment uses about five injection points and around 20 units of onabotulinumtoxinA, adjusted to your muscle strength. It takes about 10 minutes, starts working in 3–5 days, peaks at about 2 weeks and usually lasts 3–4 months.
What is frown line Botox?
When you concentrate, squint or frown, the corrugators pull the brows together and the procerus pulls them down. Over years these movements etch vertical and sometimes horizontal lines at the top of the nose. Relaxing these muscles softens the lines and gives the brow area a more open, rested look.
The glabella is the area with the most clinical evidence behind it; it was the first cosmetic use approved for botulinum toxin. It is often the best first area for anyone new to Botox.
Who is it for?
- Lines between the brows when you frown, or that remain faintly at rest.
- People told they look angry or tired when relaxed.
- Deep creases at rest may need a top-up of frown line filler or a skin booster as well.
- Not during pregnancy or breastfeeding, or with neuromuscular disorders.
