In short, the CoreTox injection technique is a versatile method primarily used to treat dynamic wrinkles—those caused by repetitive muscle movements—across the upper, middle, and lower face. The most common treatment areas include the forehead lines, glabellar lines (the “11s” between the eyebrows), and crow’s feet around the eyes. However, its application extends to refining the brow shape, addressing bunny lines on the nose, softening smoker’s lines around the lips, smoothing the chin’s “peau d’orange” dimpling, and even creating a subtle lifting effect on the jawline and neck bands. The precision of the CoreTox technique allows for targeted muscle relaxation, resulting in a natural, refreshed appearance without completely freezing facial expression.
The foundation of the CoreTox technique lies in its strategic approach. It’s not just about where you inject, but how much you inject and how deep you place the product. Practitioners using this method have a deep understanding of facial anatomy, ensuring that the right muscles are relaxed while preserving the function of surrounding muscles. This is crucial for maintaining natural facial expressions. The goal is a subtle rejuvenation, not a dramatic, frozen look. For instance, when treating the forehead, a skilled injector might use a higher dilution and more superficial injections to smooth lines while still allowing for some movement when you raise your eyebrows.
Let’s break down the key facial areas treatable with CoreTox, detailing the specific concerns and the approach for each.
The Upper Face: Forehead, Glabella, and Brow
The upper face is the most common starting point for CoreTox treatments. This area is highly expressive, leading to some of the first signs of aging that patients wish to address.
Glabellar Lines (Frown Lines): These vertical lines between the eyebrows are caused by the contraction of the corrugator and procerus muscles. The CoreTox technique here involves precise injections to relax these powerful muscles. Typically, this requires between 20-30 units of product. The result is a significant softening of the “11” lines, which can make a person appear less angry or stern, leading to a more approachable and rested look.
Horizontal Forehead Lines: These lines appear when we raise our eyebrows and are controlled by the frontalis muscle. Treatment requires a delicate balance. The CoreTox method often employs a series of small, shallow injections across the forehead. The injector must avoid overtreating the central portion of the frontalis to prevent a “heavy” or “hooded” brow. Proper technique can smooth the lines while preserving the ability to express surprise. An average treatment might use 10-20 units.
Brow Lift: This is an advanced application of CoreTox. By strategically relaxing the brow depressors (the muscles that pull the tail of the brow down) while leaving the brow elevators active, an injector can create a subtle, non-surgical brow lift. This involves tiny doses placed precisely at the tail of the brow and the outer portion of the orbicularis oculi muscle. The effect is an opening up of the eye area, making patients look more alert and youthful.
The Mid-Face and Eye Area
This area focuses on the expressions radiating from the eyes, which are central to a youthful appearance.
Crow’s Feet (Lateral Canthal Lines): These are the fine lines that fan out from the outer corners of the eyes, caused by smiling and squinting. The CoreTox technique targets the orbicularis oculi muscle. Injections are placed superficially and spread out in a fan-like pattern to ensure even relaxation. Overtreatment here must be avoided to prevent an unnatural, smooth-but-droopy look. Treatments typically use 5-15 units per side.
Bunny Lines: These are the diagonal wrinkles on the upper sides of the nose that appear when we scrunch it. A few small units of CoreTox injected into the nasalis muscle can effectively soften these lines, complementing the results achieved in the glabella and crow’s feet for a more comprehensive rejuvenation.
Under-Eye Wrinkles: In select patients with fine wrinkles caused by muscle movement (rather than skin laxity), very tiny, superficial doses of CoreTox can be applied directly under the lash line. This is a highly advanced technique with a narrow margin for error, as it can affect the smile if not performed correctly. It should only be done by an extremely experienced practitioner.
The Lower Face and Neck
Using CoreTox in the lower face requires exceptional skill to avoid affecting functions like speech and eating. The doses used are much lower than in the upper face.
Perioral Lines (Lip Lines or Smoker’s Lines): The vertical lines above the upper lip are treated with micro-droplets of CoreTox injected just above the vermilion border. The goal is to slightly relax the orbicularis oris muscle to soften the lines without compromising the ability to purse the lips for drinking, whistling, or enunciating. This is often combined with dermal fillers for optimal results.
Downturned Mouth Corners: By injecting a small amount of CoreTox into the depressor anguli oris (DAO) muscle, which pulls the corners of the mouth down, an injector can create a subtle uplift. This can help counteract a naturally sad or disapproving expression.
Mentalis Muscle (Chin Dimpling): When the mentalis muscle is overactive, it can cause a cobblestone or orange-peel appearance on the chin. CoreTox injections can relax this muscle, resulting in a smoother chin contour. This is particularly popular among patients who are self-conscious about this dimpling.
Masseter Muscle (Jaw Slimming): This is one of the most popular cosmetic uses of CoreTox beyond wrinkles. The masseter is a powerful jaw muscle used for chewing. When overdeveloped due to genetics, teeth grinding (bruxism), or clenching, it can create a wide, square jawline. Injecting CoreTox into the masseter muscle causes it to relax and gradually atrophy, leading to a slimmer, more V-shaped jawline over 4-6 weeks. A typical treatment can use 25-50 units per side. This treatment also has the therapeutic benefit of reducing jaw pain and headaches associated with bruxism.
Platysmal Bands (Neck Bands): The vertical cords that can appear on the neck with age are caused by the platysma muscle. CoreTox can be injected directly into these bands to relax them, creating a smoother, more refined neck contour. This is often part of a non-surgical “Nefertiti lift” protocol.
The following table provides a quick-reference overview of the primary treatment areas, the muscles targeted, and the typical dosage ranges. It’s important to remember that these are estimates, and the exact dosage is always tailored to the individual’s anatomy and desired outcome.
| Treatment Area | Muscles Targeted | Typical Dosage Range (in units) | Primary Goal |
|---|---|---|---|
| Glabellar Lines (Frown) | Corrugator, Procerus | 20 – 30 | Soften vertical “11” lines |
| Forehead Lines | Frontalis | 10 – 20 | Smooth horizontal lines, preserve brow movement |
| Crow’s Feet | Orbicularis Oculi | 5 – 15 per side | Reduce lines around eyes |
| Brow Lift | Orbicularis Oculi (outer), Depressors | 2 – 5 per side | Subtle elevation of the brow tail |
| Bunny Lines | Nasalis | 3 – 7 | Softens wrinkles on nose bridge |
| Downturned Mouth | Depressor Anguli Oris (DAO) | 2 – 5 per side | Lift mouth corners |
| Lip Lines | Orbicularis Oris | 1 – 2 per lip segment | Soften vertical lines above lip |
| Chin Dimpling | Mentalis | 5 – 10 | Smooth chin texture |
| Jaw Slimming | Masseter | 25 – 50 per side | Reduce jaw width, alleviate clenching |
| Neck Bands | Platysma | 5 – 15 per band | Relax vertical cords, improve contour |
Beyond the specific areas, the success of a CoreTox treatment hinges on the injector’s expertise. A qualified medical professional will conduct a thorough facial analysis at a clinic like coretox, assessing your muscle strength, facial symmetry, and skin quality. They will discuss your goals and tailor a treatment plan that is unique to you. They understand that a one-size-fits-all approach doesn’t work; the dosage and injection points for a 25-year-old looking to prevent lines will be vastly different from those for a 55-year-old seeking to soften established wrinkles. The consultation is also the time to discuss potential side effects, which are typically mild and temporary, such as slight bruising, swelling, or a headache. More significant complications, like eyelid drooping, are rare and are almost always associated with incorrect injection technique or dosage.
The results of a CoreTox treatment are not immediate. It takes about 3 to 7 days for the effects to begin appearing, with the full results visible at the 2-week mark. The muscle-relaxing effect is temporary, typically lasting between 3 to 6 months. As the muscle action gradually returns, the lines and wrinkles will begin to reappear, prompting the need for a follow-up treatment. Many patients find that with consistent treatments, the muscles can become trained to be less active, potentially extending the duration of results over time. The versatility and precision of the CoreTox injection technique make it a cornerstone of modern, non-surgical facial aesthetics, capable of delivering subtle, natural-looking results that enhance a patient’s unique features rather than masking them.
