Glabellar lines are the vertical wrinkles or creases that form between the eyebrows on the forehead. These lines are called “glabellar” because they are in the glabella, which is the smooth, skin-covered area of the forehead just above the nose and between the eyebrows.
Glabellar lines are primarily caused by the repeated contraction of the muscles in the forehead, particularly the corrugator supercilii and procerus muscles. These muscles are responsible for controlling the movements of the eyebrows and are used when we frown, squint, or express other negative emotions.
Epidemiology
Glabellar lines are a common cosmetic concern, and many adults develop them to varying degrees as they age. The prevalence of glabellar lines increases with age, with more pronounced lines typically seen in older individuals.
While it is challenging to provide precise prevalence figures, a substantial portion of the adult population may experience some degree of glabellar lines.
Age is a significant factor in the development of glabellar lines. These lines tend to become more prominent as people get older due to the natural aging process, which includes a decrease in skin elasticity and collagen production. Glabellar lines can affect both men and women, but there may be some gender differences in terms of prevalence and severity.
Anatomy
Pathophysiology
The primary underlying cause of glabellar lines is the repetitive contraction of specific facial muscles. The muscles primarily involved in the formation of these lines are the corrugator supercilii and procerus muscles. These muscles are responsible for controlling the movement of the eyebrows and are activated when we frown, squint, or express negative emotions.
Aging is a significant factor in the pathophysiology of glabellar lines. As individuals age, the skin undergoes several changes, including a decrease in the production of collagen and elastin fibers. Collagen and elastin are essential proteins that provide the skin with strength and elasticity. The reduction in these proteins makes the skin less resilient and more prone to developing wrinkles, including glabellar lines.
The loss of skin elasticity is a crucial factor in the formation of glabellar lines. Younger skin can bounce back to its original position after muscle contractions, but as skin ages, it loses its ability to do so.
Etiology
Repetitive muscle contractions in the forehead area are a primary cause of glabellar lines. The corrugator supercilii and procerus muscles plays a significant role in the formation of these lines. These muscles are responsible for controlling eyebrow movements and are activated when we frown, squint, or express negative emotions.
Genetic factors can influence an individual’s predisposition to developing glabellar lines. Ultraviolet (UV) radiation from the sun is a major environmental factor that accelerates skin aging and contributes to the development of glabellar lines.
Prolonged and unprotected sun exposure can lead to the breakdown of collagen and elastin fibers, as well as the generation of free radicals, which damage skin cells and promote wrinkles.
Poor nutrition, inadequate hydration, and a lack of proper skincare can also influence the formation and severity of glabellar lines. A well-balanced diet, hydration, and skincare routines that include sun protection can help mitigate the effects of aging on the skin.
Genetics
Prognostic Factors
The initial severity of glabellar lines can impact their prognosis. Mild lines may respond better to non-invasive treatments and have a more favorable outcome compared to deep and well-established lines.
Skin type and genetics play a role in the prognosis of glabellar lines. People with thicker and more resilient skin may experience slower progression of lines and a better response to treatments. On the other hand, individuals with thinner or less elastic skin may be more prone to developing and worsening glabellar lines.
Sun exposure is a key environmental factor that influences the prognosis of glabellar lines. Protecting the skin from UV radiation through sunscreen use and other sun-protective measures can help slow the progression of lines and improve treatment outcomes.
Lifestyle factors such as smoking, poor nutrition, and dehydration can negatively impact the prognosis of glabellar lines. Smoking accelerates skin aging and may make lines more pronounced.
Clinical History
Glabellar lines are typically less common and less pronounced in younger adults. People in their 20s and 30s generally have more youthful, resilient skin with a good amount of collagen and elastin, which provides skin elasticity.
Glabellar lines may appear as fine lines, especially during facial expressions like frowning or squinting, but they are often temporary and disappear when the facial muscles relax.
Glabellar lines become more noticeable and persistent as individuals enter their 40s and 50s. Skin begins to show signs of aging, including a decrease in collagen and elastin production. Wrinkles and fine lines, including glabellar lines, may be present even when facial muscles are at rest.
Physical Examination
Visual Assessment: The healthcare provider will visually assess the glabellar lines while the patient maintains a neutral facial expression and possibly while making various facial expressions, including frowning, or squinting. The severity and depth of the lines are carefully examined.
Muscle Movement: The provider may ask the patient to contract the muscles in the forehead by frowning or raising the eyebrows. This allows the examiner to evaluate the dynamic nature of the lines and how they change with muscle movement.
Skin Quality: The texture and quality of the skin in the glabellar region are examined. This includes assessing the skin’s elasticity, thickness, and any signs of sun damage, such as pigmentation or uneven skin tone.
Wrinkle examination: The depth of the glabellar lines is assessed to determine whether they are fine lines or deep creases. Deeper lines may require different treatment approaches.
Age group
Associated comorbidity
Excessive sun exposure is a known contributor to the development of wrinkles, including glabellar lines. Prolonged and unprotected sun exposure can increase the risk of skin damage, premature aging, and even skin cancer.
Smoking is another factor that accelerates skin aging and is associated with an increased risk of wrinkles, including glabellar lines. Quitting smoking can have significant health benefits beyond improving the appearance of your skin, as it reduces the risk of various serious health conditions, including lung cancer and cardiovascular disease.
While glabellar lines themselves are not a comorbidity, maintaining healthy skin is important for overall well-being. Proper skincare, including moisturizing and protecting your skin from environmental damage, can help preserve skin health and appearance.
Associated activity
Acuity of presentation
Lifestyle choices can greatly impact the acuity of glabellar lines. Factors such as sun exposure, smoking, and overall skincare practices can influence how quickly and severely these lines develop. Prolonged sun exposure and smoking, for example, can accelerate skin aging and lead to more prominent lines.
Proper skincare practices, including moisturizing and sun protection, can help delay the onset of glabellar lines and reduce their acuity. Regular use of sunscreen and anti-aging products may slow down the progression of lines.
The frequency and intensity of facial expressions that involve frowning, squinting, or furrowing the brow can affect how quickly and severely glabellar lines appear. Individuals with expressive faces or those who frequently engage in such expressions may develop lines earlier and more acutely.
Differential Diagnoses
Dynamic Lines: Dynamic lines appear when facial muscles contract and disappear when the muscles relax. They are often treated with botulinum toxin injections to temporarily relax the muscles.
Static lines: Static lines are present even when the facial muscles are at rest. These lines may require treatments such as dermal fillers to add volume and smoothen the skin.
Adjunctive Treatments: In addition to evaluating glabellar lines, healthcare providers may assess other facial areas for signs of aging, such as crow’s feet, forehead lines, or nasolabial folds.

Treatment Paradigm
Skin Care and Sun Protection: As part of a comprehensive approach, the provider may recommend a daily skincare regimen, including the use of sunscreen and moisturizers, to protect and maintain the skin. Proper skincare helps prevent further damage and may improve skin quality.
Botulinum Toxin Injections: Botulinum toxin injections are a common and effective treatment for dynamic glabellar lines, which appear when facial muscles contract.
Dermal Fillers: For static glabellar lines, which are present even when the facial muscles are at rest, dermal fillers may be recommended. Fillers can add volume to the area and smooth out the lines.
Skincare Maintenance: Patients are encouraged to continue with their skincare regimen, sun protection, and overall healthy lifestyle practices to maintain the results of their treatments.
Sun Protection: Sun exposure is a significant contributor to skin aging and the development of wrinkles, including glabellar lines. Protect your skin from the sun by:
Hydration: Proper skin hydration is essential for maintaining skin health and minimizing the appearance of lines. Drink plenty of water throughout the day to keep your skin hydrated from the inside out.
Healthy Diet: A balanced diet rich in fruits, vegetables, lean proteins, and essential nutrients can support skin health. Antioxidant-rich foods, such as berries and leafy greens, may help protect against free radical damage that accelerates aging.
Smoking Cessation: Smoking is known to accelerate skin aging and increase the risk of wrinkles, including glabellar lines. Quitting smoking can have a positive impact on your skin’s appearance and overall health.
Avoid Harsh Skin Care Products: Some skincare products and treatments may be harsh on the skin and exacerbate the appearance of lines. Consult with a dermatologist to choose products that are appropriate for your skin type and concerns.
Facial Expressions: Be mindful of repetitive facial expressions, such as frowning or squinting. While you can’t eliminate these expressions altogether, being aware of them may help reduce their frequency.
Better Sleep Position: Sleeping on your back instead of your stomach or side can help minimize sleep lines and creases that can contribute to the formation of glabellar lines.
Stress Management: Chronic stress can contribute to premature aging and skin concerns. Practice stress-reduction techniques such as meditation, deep breathing, or yoga to promote relaxation and overall well-being.
Use of Botulinum toxin injections
Botulinum toxin type A: including AbobotulinumtoxinA, is known for its ability to temporarily relax the muscles responsible for causing dynamic wrinkles, such as those seen in the glabellar region.
AbobotulinumtoxinA: It works by blocking the release of acetylcholine, a neurotransmitter, from nerve endings that control muscle contractions.
When injected into the targeted muscles of the glabellar region, Abobotulinumtoxin A temporarily inhibits these muscles’ ability to contract forcefully.
Abobotulinumtoxin A is particularly effective in treating dynamic lines by relaxing the muscles responsible for these expressions.
Botulinum Toxin Injections: These are one of the most popular and effective treatments for dynamic glabellar lines, which appear when facial muscles contract during expressions like frowning.
Dermal Fillers: Dermal fillers are used to treat static glabellar lines, which are present even when the facial muscles are at rest.
Fillers contain substances like hyaluronic acid or calcium hydroxylapatite, which are injected beneath the skin to add volume and smooth out wrinkles.
