Introduction
The face is an incredible instrument of communication, capable of conveying deep joy, intense focus, and subtle concern through a single movement. However, many of us have experienced that moment in front of the mirror where we notice two vertical lines beginning to take up permanent residence between our eyebrows. Whether they appear after a long week of work or seem more pronounced after a day in the sun, these lines are often the first sign of maturity we notice on our complexions. At Yon-Ka Paris, we believe that understanding the biology of your skin is the first step toward a more mindful and effective skincare ritual.
In this article, we will identify the professional and common names for these vertical creases, explore the underlying anatomical causes, and discuss how botanical science can help smooth their appearance. We will also outline a dedicated phyto-aromatic routine designed to support skin resilience and maintain a serene, youthful look. By understanding the “why” behind these lines, you can transition from temporary fixes to a holistic, long-term approach to skin health.
The Technical and Common Names for Between-Eye Wrinkles
If you have ever asked a dermatologist or an esthetician about the lines between your eyes, they likely used the term glabellar lines. This technical name is derived from the “glabella,” the anatomical region of the forehead located between the eyebrows and just above the nose. While “glabellar lines” is the medical term, these wrinkles have several descriptive nicknames in the beauty world.
Most commonly, they are referred to as “11 lines” because they frequently appear as two parallel vertical marks that resemble the number eleven. They are also widely known as frown lines or worry lines, as they are most visible when we contract the muscles in the center of the forehead during moments of frustration, deep concentration, or stress.
While these names might suggest a negative emotion, it is important to remember that these marks are simply a map of your face’s movement. Whether you are squinting at a bright screen or knitting your brows while reading a favorite book, these lines are a natural result of a life full of expression and engagement with the world.
The Anatomy of a Frown: How Lines Form
To effectively address glabellar lines, we must look beneath the surface of the skin. Unlike fine lines caused by simple surface dehydration, the wrinkles between the eyes are categorized as dynamic wrinkles.
The Role of Facial Muscles
Dynamic wrinkles are formed by the repeated contraction of underlying muscles. In the glabella area, two primary muscles are the architects of these lines:
- The Corrugator Supercilii: These are small, narrow muscles located at the inner end of each eyebrow. Their primary job is to pull the eyebrows together and downward, which creates the vertical furrow.
- The Procerus: This muscle sits between the eyebrows and over the bridge of the nose. When it contracts, it pulls the skin of the forehead down, often contributing to the horizontal lines sometimes seen at the top of the nasal bridge.
From Dynamic to Static
When we are young, our skin is rich in collagen and elastin. When you stop frowning, the skin immediately returns to a smooth state. However, as we age, the production of these essential proteins slows down.
Over time, the repeated mechanical stress of muscle contraction breaks down the dermal matrix. Eventually, the “memory” of those expressions remains even when your face is totally relaxed. This is when dynamic wrinkles become static wrinkles—lines that are visible at all times.
Quick Answer: The wrinkles between the eyes are professionally called glabellar lines, though they are commonly known as “11 lines” or “frown lines.” They are caused by the repeated contraction of the corrugator and procerus muscles combined with the natural loss of collagen and elastin over time.
Primary Causes of Glabellar Lines
While muscle movement is the main trigger, several internal and external factors influence how deeply these lines set and how early they appear in your life.
The Natural Aging Process
As we move through our 30s and 40s, the skin’s natural repair mechanisms begin to decelerate. The dermis becomes thinner, and the stores of hyaluronic acid begin to deplete. This loss of internal volume makes the skin less resilient against the constant tugging of facial muscles.

UV Exposure and Photo-Aging
The sun is perhaps the most significant external factor in the development of deep wrinkles. UV rays penetrate deep into the dermis and trigger the release of enzymes that break down collagen and elastin. Because the skin in the glabella area is relatively thin, it is particularly vulnerable to this “solar elastosis.” Furthermore, bright sunlight causes us to squint, which keeps the corrugator muscles in a state of constant tension.
Digital Strain and “Computer Face”
In our modern, tech-heavy lives, many of us spend hours focusing on smartphones, tablets, and monitors. This often leads to “unconscious frowning” as we strain to read small text or concentrate on complex data. This repetitive tension can lead to the premature appearance of 11 lines, even in individuals in their 20s.
Lifestyle Factors
Smoking and poor nutrition also play a role. Smoking restricts blood flow to the skin, depriving it of the oxygen and nutrients needed for repair, while a diet high in processed sugars can lead to glycation. Glycation is a process where sugar molecules attach to collagen fibers, making them stiff and brittle rather than supple and elastic.
The Phyto-Aromatic Approach to Smoothing
Our philosophy at Yon-Ka is rooted in the synergy of four plant sciences: aromatherapy, phytotherapy, aromachology, and marine biology. To address the appearance of glabellar lines, we do not look for a single “miracle” ingredient. Instead, we focus on a holistic approach that relaxes the look of tension, densifies the skin’s structure, and provides intense, multi-level hydration.
Learn more about Yon-Ka’s botanical ingredients and phyto-aromatic approach.
The heart of our formulation is the Quintessence. This exclusive complex of five essential oils—lavender, geranium, rosemary, cypress, and thyme—is 100% natural and active. For the glabella area, rosemary is particularly beneficial as it supports a firming and revitalizing appearance, while lavender provides a soothing aromatic effect that helps ease the sensorial feeling of facial tension.
Note: When introducing new products containing high concentrations of essential oils or botanical actives, we recommend performing a patch test on your inner forearm for 24 hours. Introduce one new product at a time to allow your skin to adjust. A slight, temporary tingling sensation can be normal, but persistent redness means you should reduce frequency or discontinue use.
Building Your Ritual for 11 Lines
Addressing the wrinkles between your eyes requires a consistent, layered ritual. Because these lines are deep and structurally based, a “cleanse and forget” approach is rarely enough. We recommend a focused routine that prepares, treats, and protects the skin.
Step 1: Gentle, Barrier-Respecting Cleansing
A harsh cleanser can strip the skin of its natural oils, making fine lines look more prominent due to dehydration. Use a creamy, hydrating option like Lait Nettoyant. This cleansing milk respects the skin’s delicate acid mantle while removing impurities, ensuring the skin is soft and ready for subsequent steps.
Step 2: The Phyto-Aromatic Mist
The most critical “prep” step in any Yon-Ka ritual is the application of Lotion Yon-Ka. This is not a traditional toner; it is a phyto-aromatic “healing water” that drenches the skin in our signature Quintessence. By hydrating the outermost layer of the skin, it acts as a conductor, allowing the active ingredients in your serums and creams to penetrate more deeply and work more effectively.
Step 3: Targeted Serums for Density
Serums are the powerhouses of your routine. When dealing with glabellar lines, look for formulas that support the skin’s structural integrity. Yon-Ka’s serums and elixirs offer targeted options for hydration, firmness, and visible signs of aging.
- Serum C20: This potent serum features a stable version of Vitamin C, a legendary antioxidant that helps support the appearance of collagen-rich skin. It helps the skin look brighter and more resilient against environmental stress.
- Serum Omega: If your skin feels thin or “crepy,” this lipid-restoring oil-in-serum provides essential fatty acids. A strengthened skin barrier means better moisture retention, which helps “plump” the look of lines from within.
Step 4: Specific Care for the “Expression Zone”
The skin between the eyes shares many characteristics with the skin around the eyes—it is thinner and has fewer oil glands than the rest of the face. Phyto-Contour is a professional-grade eye cream that is equally effective when applied to the glabella. Its high concentration of rosemary helps provide a firming, “lifted” sensation that is particularly refreshing for a tired-looking forehead.
Step 5: Smoothing and Resurfacing Moisturizers
Your moisturizer acts as the final “seal” in your ritual, providing long-term structural support. Yon-Ka’s Age Correction collection includes formulas designed to support the appearance of firmness and smoother-looking skin.
- Time Resist Jour: For those with established 11 lines, the Time Resist collection uses plant-based stem cells and youth-activating ingredients to help smooth the appearance of deep furrows.
- Excellence Code Crème: This premium cream is designed for mature skin. It addresses all signs of aging, including loss of firmness and deep wrinkles, using a blend of avocado, shea butter, and specialized botanical complexes.
Key Botanical Ingredients to Look For
When reading ingredient labels for products targeting glabellar lines, look for these scientifically backed botanical powerhouses. Yon-Ka explains its approach to active ingredients and product development on its formulas page.
- Hyaluronic Acid: A humectant that pulls water into the skin. In formulas like Hydra n°1 Crème, it provides immediate “plumping” to make lines look less deep.
- Peptides: These are short chains of amino acids that act as messengers to the skin. They can help the skin look firmer and more organized, reducing the “sag” that contributes to deep creases.
- Glycolic Acid: An alpha-hydroxy acid derived from sugar cane. It works by gently dissolving the “glue” that holds dead skin cells together. Products like Glyconight 10% Masque use glycolic acid to resurface the skin overnight, helping to smooth the texture of fine lines and deep wrinkles alike.
- Beech Bud Peptides: Often referred to as the “tree of eternal youth,” beech bud extracts help improve skin oxygenation and smooth the appearance of the cutaneous micro-relief.
Key Takeaway: Glabellar lines are complex because they involve both muscle tension and structural skin changes. A successful ritual must combine “relaxing” botanical mists, “plumping” hyaluronic acid, and “resurfacing” AHAs to see a visible improvement in skin texture.
The Importance of Professional Treatments
While a home ritual is the foundation of skin health, professional intervention can take your results to the next level. In a spa setting, a Yon-Ka certified esthetician can perform deep-tissue massage techniques specifically designed to relax the corrugator muscles.
Treatments like the Alpha-Vital resurfacing facial or the Excellence Code anti-aging treatment use professional-strength concentrations of botanical actives and specialized tools to target deep expression lines. These treatments often include manual sculpting movements that “iron out” the look of tension in the forehead.

Lifestyle Habits to Prevent Deepening Lines
Skincare is most effective when supported by healthy daily habits. To prevent your glabellar lines from deepening prematurely, consider these practical adjustments:
- Wear Sunglasses: This is the simplest way to prevent “squint lines.” Ensure your sunglasses offer 100% UV protection and are large enough to cover the entire eye and glabella area.
- Manage Digital Strain: If you work at a computer, follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This relaxes the eye muscles and helps prevent unconscious frowning.
- Stay Hydrated: Dehydrated skin is less elastic. Drinking plenty of water ensures your cells are “plump” from the inside out.
- Sleep Positioning: If possible, try to sleep on your back. Pressing your face into a pillow for eight hours a night can create “sleep lines” that eventually turn into permanent wrinkles.
- Facial Massage: During your evening ritual, use your index and middle fingers to gently “sweep” from the center of your eyebrows outward toward your temples. This simple movement helps release the physical tension held in the procerus muscle.
Summary of Action Steps
If you are ready to address the wrinkles between your eyes, here is your path forward:
- Identify the Stage: Determine if your lines are dynamic (only there when you frown) or static (there all the time). This helps you choose between preventative care or intensive treatment.
- Optimize Your Prep: Never skip your Lotion Yon-Ka. It is the key to making every other product in your routine work harder.
- Introduce a Targeted Serum: Choose a formula like Serum C20 for antioxidant protection or Serum Omega for structural nourishment.
- Focus on the Eyes: Apply your eye contour product, such as Phyto-Contour, directly to the glabella area to benefit from its firming properties.
- Protect Daily: Apply broad-spectrum sunscreen every single morning, regardless of the weather. UV damage is the primary cause of collagen breakdown.

FAQ
Can skincare products completely remove deep “11 lines”?
While topical skincare cannot “erase” a deep static wrinkle in the same way a medical procedure might, high-quality botanical formulas can significantly reduce their appearance. By deeply hydrating the skin and supporting collagen production, products can “plump” the furrow, making it look much shallower and less noticeable to the eye.
At what age should I start using products for glabellar lines?
Prevention is always more effective than correction. It is wise to start a dedicated anti-aging ritual in your late 20s or early 30s, focusing on antioxidant protection and hydration. However, it is never too late to start; botanical actives like peptides and AHAs can provide visible smoothing benefits at any stage of life.
Why do my frown lines look worse in the morning?
This is often due to overnight dehydration or “sleep wrinkles” caused by your face being pressed against a pillow. Using a rich, lipid-restoring night treatment like Serum Omega or an overnight mask like Glyconight 10% Masque can help keep the skin hydrated and resilient throughout the night.

Does facial massage actually help with wrinkles between the eyes?
Yes, manual massage can be very effective for “dynamic” wrinkles. By gently stretching and relaxing the corrugator muscles, you can help prevent them from staying in a semi-contracted state. When combined with a phyto-aromatic oil, this practice also helps stimulate local micro-circulation, bringing more oxygen and nutrients to the skin’s surface.
