Lines between the eyebrows — often called “frown lines,” “glabellar lines,” or the “11s” — are a common facial concern. At first, these creases only show when you frown, concentrate, or squint. Over time, repeated movement and changes in the skin can make them visible even when your face is relaxed.
What Causes Frown Lines?
Frown lines form through a mix of natural ageing and expression-related movements:
-
Muscle activity: Frequent brow furrowing contracts the corrugator and procerus muscles, creating lines over time.
-
Collagen loss: As skin ages, it produces less collagen and elastin, making it less firm and hydrated and more prone to creasing.
-
Sun exposure & environment: UV damage accelerates wrinkle formation by breaking down structural proteins in the skin.
-
Genetics & tension: Some people are more predisposed to deeper creases, especially if they habitually furrow their brows.
These factors mean that frown lines are a normal part of aging — but they don’t have to be a permanent fixture.
How Frown Lines Are Treated
There’s no single “best” solution for everyone, because the ideal approach varies with skin type, age, and the depth of the lines. A mix of treatments often delivers the most balanced result.
“Frown lines develop through repeated muscle movement and changes in skin quality,” says Dr Phil Frost, Founder and Medical Director of Face Value Cosmetic Medicine. “Relaxing the underlying muscles while also supporting collagen and skin texture gives the most natural-looking improvement.”
This view reflects how both muscle activity and skin quality play roles in crease formation. Here are the main options commonly used:
Botulinum Toxin (e.g., Botox®)
Botulinum toxin injections calm the muscles that create dynamic wrinkles, softening lines between the brows and preventing them from deepening. Results typically appear within a week and can last around three to four months.
Microneedling
This treatment uses tiny needles to create controlled micro-injuries that trigger natural collagen production. Over a series of sessions, it can improve skin texture and soften early static lines.
PRP (Platelet-Rich Plasma) Therapy
PRP uses your own blood’s growth factors to support tissue regeneration. When combined with microneedling or used on its own, it can enhance skin vitality and address deeper textural concerns.
Radiofrequency Needling (RF)
By merging microneedling with heat energy, RF treatments can firm and tighten skin at deeper levels, helping reduce more established wrinkles.
Can You Prevent Frown Lines?
While ageing is unavoidable, certain habits can help slow the progression of lines:
-
Wear sunglasses to reduce squinting in bright light
-
Use daily SPF to protect against UV-related collagen breakdown
-
Manage facial tension and stress
-
Stay hydrated and maintain skin health with quality skincare
Over time, early maintenance and protective habits can make a noticeable difference.
Final Thoughts
Frown lines result from a combination of muscle movement, ageing, sun exposure, and lifestyle patterns. The best approach typically blends muscle-relaxing techniques with treatments that promote collagen and support skin texture. With thoughtful planning and professional guidance, smoother, more natural-looking skin is achievable without surgery.
