Introduction
There is a specific moment in a morning ritual when the light hits the mirror just right and you notice two small, vertical lines settled between your eyebrows. Often appearing during a focused work session or a bright afternoon outdoors, these etchings can make us look perpetually worried or tired, even when we feel perfectly vibrant. At Yon-Ka Paris, we view these lines not as flaws, but as part of the skin’s unique narrative—one that we can support with intentional, botanical-led care.
The wrinkles between your eyes are called glabellar lines, also commonly known as 11 lines or frown lines. By understanding the science of the glabella and the power of plant-based actives, you can transform your routine into a rejuvenating ceremony for the skin. Consistent rituals help maintain a smooth, resilient brow while honoring our brand story.
Quick Answer: The vertical wrinkles between your eyes are professionally known as glabellar lines. Also called 11 lines or frown lines, they form in the glabella area (the skin between your eyebrows) primarily due to repetitive facial expressions like squinting or concentrating.
The Professional and Common Names for Brow Furrows
When we talk about the skin between the eyes and above the bridge of the nose, we are referring to a small but highly expressive area called the glabella. Consequently, the most accurate medical and aesthetic term for these wrinkles is glabellar lines. Because these wrinkles almost always appear as two parallel vertical marks, the nickname "11 lines" (or "elevens") has become a standard term in the skincare world, and it’s a good place to start if you’re exploring our wrinkle collection.
While "frown lines" is perhaps the most frequent common name, it is a bit of a misnomer. These creases do not only form when we are unhappy; they are the result of any repetitive facial contraction, including intense focus, squinting against the sun, or even deep thought.
Vertical vs. Horizontal Lines
It is important to distinguish glabellar lines from other forehead wrinkles. While glabellar lines are vertical and located specifically between the eyebrows, horizontal forehead lines run across the width of the forehead. These are caused by the upward movement of the brows. You may also notice tiny diagonal lines at the top of the nose, often called bunny lines. Recognizing these distinctions is the first step in choosing the right targeted treatments from our eye and lip contour range.
| Line Type | Location | Primary Cause |
|---|---|---|
| Glabellar Lines (11 Lines) | Between the eyebrows | Frowning, squinting, or intense focus |
| Horizontal Forehead Lines | Across the width of the forehead | Raising the eyebrows upward |
| Bunny Lines | On the bridge or sides of the nose | Scrunching the nose or squinting |
The Anatomy of an Expression: Why They Form
To understand why these lines appear, we must look beneath the surface. Glabellar lines are primarily dynamic wrinkles in their early stages, appearing only when a muscle contracts. Over time, these can transition into static wrinkles, which remain visible even when your facial muscles are completely at rest.
The Muscles Involved
The formation of 11 lines is driven by two main muscle groups:
- The Corrugator Supercilii: These are two small, pyramid-shaped muscles located at the inner end of each eyebrow that pull the brows inward and downward.
- The Procerus: This muscle sits between the brows and runs to the bridge of the nose, pulling the skin down and contributing to regional creases.
Every time these muscles contract, the overlying skin is folded. In youth, structural proteins allow the skin to "snap back" instantly. As we mature, the skin’s "memory" of these folds becomes more permanent.
Key Takeaway: 11 lines result from a combination of repetitive muscular movement and the biological loss of skin resilience. Protecting the skin from UV and screen-related tension is as critical as the products we apply.
Biological and Lifestyle Factors of Skin Aging
The transition from a temporary expression to a permanent line is influenced by internal and external factors. Understanding these helps us adapt our rituals, which is why many look to an anti-aging collection for support.
Collagen and Elastin Depletion
Collagen acts as the skin’s scaffolding, while elastin provides the elasticity that allows skin to bounce back. Starting in our mid-twenties, natural production of these proteins slows down, making it harder for the "dents" created by facial expressions to fill back in.
Glycation and Skin Rigidity
In glycation, sugar molecules attach to collagen fibers, causing them to become stiff and brittle. Rigid skin is much more prone to wrinkling under the pressure of muscular movement.
Environmental Triggers: UV and Screens
UV exposure is the leading cause of premature aging, breaking down the dermal matrix and causing us to squint. Furthermore, "screen squinting" has become a major contributor in the digital age. We often subconsciously furrow our brows while reading small text on devices, keeping muscles in constant tension. For more practical habits, see our wrinkle-prevention tips.
The Phyto-Aromatic Approach to Smoothing
At Yon-Ka, we focus on phyto-aromatic formulas that support the skin’s natural repair mechanisms and encourage relaxation through aromachology. You can learn more about this in our formulation philosophy.
The Power of the Quintessence
The foundation of our brand is the Quintessence, an exclusive complex of five essential oils: lavender, geranium, rosemary, cypress, and thyme. This 100% natural complex is integrated into our formulas to provide multiple benefits for the brow area. To explore these ingredients, visit our ingredients page.
- Lavender and Geranium: Offer soothing properties to calm the look of stressed skin.
- Rosemary: Known for firming and revitalizing effects.
- Cypress and Thyme: Support the skin's overall tone and purification.
Quick Summary:
- Glabellar lines (or 11 lines) are the vertical furrows between the brows.
- They form due to repetitive muscle tension, collagen loss, and glycation.
- UV exposure and "screen squinting" are major lifestyle accelerators.
- A comprehensive care approach involves exfoliating, hydrating, and targeting the area with specific serums and moisturizers.
A Targeted Ritual for the Glabellar Area
Correcting the appearance of lines between the eyes requires a consistent, layered approach.
Step 1: Prepare with Gentle Resurfacing
Dead skin cells can settle into wrinkles, making them appear deeper. We recommend using Gommage Yon-Ka, our grain-free exfoliator. Using this 1–2 times a week ensures that your targeted serums can penetrate more effectively.
Step 2: Drench the Skin in Hydration
Dehydrated skin makes every line look like a deep valley. After cleansing, mist the face with Lotion Yon-Ka PS. Ensure the mist is well-absorbed to provide an initial "plump" to the surface cells.
Step 3: Targeted Serum Application
- For Brightening and Defense: Use Serum C20. With a 20% stable Vitamin C concentration, it helps protect against the environmental damage that accelerates wrinkle formation.
- For Intense Repair: Elixir Vital is an SOS treatment that uses beech bud peptides to support skin smoothness.
- For Lipid Restoration: Serum Omega provides essential fatty acids to make the brow area look more supple.
Step 4: Moisturize and Fill
Finish with a cream like Time Resist Jour, which features microspheres of hyaluronic acid to "fill" the appearance of lines on the surface.
Note: Patch test on the inner forearm for 24 hours before use. Introduce one new product at a time to allow your skin to acclimate, and reduce frequency if redness persists.
Professional Ingredients to Look For
Look for these key ingredients prioritized in our French laboratory:
- Peptides: Beech bud peptides act as messengers to help the skin look firmer and revitalized.
- Hyaluronic Acid: We use various molecular weights to ensure both surface plumping and deeper hydration.
- Vitamin C: A gold-standard antioxidant that defends against oxidative stress. For more, read our Vitamin C guide.
- Aromatic Essential Oils: Oils like Rosemary, found in Phyto 52, have a natural firming effect.
The Art of the At-Home Brow Massage
Incorporating a 60-second massage into your nightly ritual can help release the muscular tension that causes 11 lines to become static. After applying Time Resist Nuit, follow these steps:
- Step 1: Place your index and middle fingers at the start of your eyebrows near the bridge of the nose.
- Step 2: Apply firm, gentle pressure and slowly slide your fingers outward toward the temples.
- Step 3: Use your thumb and index finger to gently "pinch" along the length of the eyebrow to relax the corrugator muscles.
- Step 4: Place the palm of your hand flat against your forehead and move it in a slow, upward circular motion.
The Professional Spa Connection
Professional treatments can offer deeper results for etched-in lines. Many clients find that professional chemical peels or our facial treatments provide a "reset" for the skin using specialized massage and professional-strength AHAs.
Maintaining a Smooth Brow: The Long Game
Wrinkles do not form overnight, and their appearance will not change overnight. Consistency in your daily ritual is key.
Beyond topical products, remember to:
- Wear Sunglasses: This prevents involuntary squinting.
- Stay Hydrated: Internal hydration is as vital as topical care.
- Manage Stress: Practices like deep breathing can help relax the facial muscles associated with "worry lines."
Bottom line: While glabellar lines are a natural part of an expressive life, a ritual-based approach using phyto-aromatic ingredients can significantly soften their appearance and support the skin's long-term resilience.

FAQ
Can you get rid of 11 lines without Botox?
While Botox "freezes" the muscle to prevent movement, you can significantly soften the appearance of 11 lines through consistent skincare. Using products with hyaluronic acid, peptides, and Vitamin C—such as those in our Time Resist range—helps plump the skin and improve the look of surface texture. Regular facial massage and religious sunscreen use are also effective non-invasive strategies. If you want in-person support, use our Spa Locator to find a Yon-Ka spa near you.
At what age do frown lines usually start appearing?
Most people begin to notice dynamic frown lines in their late 20s or early 30s as collagen production naturally starts to slow. By the 40s and 50s, these lines often become static, meaning they are visible even when the face is at rest. However, genetics, sun exposure habits, and "screen squinting" can cause them to appear earlier or later.
Do facial exercises help with glabellar lines?
There is limited scientific evidence that "facial yoga" or exercises can eliminate wrinkles; in some cases, repetitive movement can actually deepen expression lines. Instead of exercise, we recommend facial massage and relaxation techniques. Focusing on releasing tension in the procerus and corrugator muscles helps prevent the skin from being constantly folded.
What is the difference between frown lines and forehead wrinkles?
Frown lines (glabellar lines) are the vertical creases located specifically between the eyebrows, caused by pulling the brows together. Forehead wrinkles are the horizontal lines that run across the upper face, caused by raising the eyebrows. Both are considered "expression lines," but they involve different muscle groups and require slightly different application techniques for topical treatments.
