Everything you need to know about your first anti-wrinkle injections

Everything you need to know about your first anti-wrinkle injections


At some point, you start noticing lines that no longer disappear when your face is at rest. Your forehead holds tension. The area around your eyes looks tired even when you feel fine. You may feel that your face is telling a story of stress or fatigue that does not match how you actually feel inside.


For most women, considering anti-wrinkle injections is not about changing their face. It is about softening what feels heavy, easing what feels tense, and reconnecting with a version of themselves that feels familiar. You want to look refreshed, not altered. You want subtlety, not drama.


At Herrera MD, medspa and aesthetic services,  every aesthetic journey begins with a thoughtful, physician-led approach. I am Dr. Brenda Herrera, an internal medicine physician with nearly two decades of experience. I help women feel aligned with their reflection again through personalized, medically guided care. You can explore our injectables and PRP clinic to understand how we blend science, precision, and artistry.


What are anti-wrinkle injections?


Anti-wrinkle injections are treatments designed to relax specific facial muscles responsible for expression-related lines. These are known as dynamic wrinkles, meaning they form from repeated movement such as frowning, raising the eyebrows, squinting, or smiling.


The active ingredient is a purified protein that temporarily blocks the chemical signals between nerves and targeted muscles. When these muscles relax, the overlying skin smooths and the appearance of wrinkles softens.


Anti-wrinkle injections do not affect untreated muscles. This means your natural expressions remain intact. When performed correctly, the face still moves and emotes, but with less tension and less creasing.


How anti-wrinkle injections work in the skin and muscles


Facial wrinkles caused by movement develop because certain muscles contract repeatedly over time. These contractions fold the skin in the same areas repeatedly, eventually creating lines that remain visible even at rest.


Anti-wrinkle injections work by reducing the strength of these muscle contractions. As the targeted muscles relax, the skin above them can smooth and recover. Over time, this not only softens existing lines but also helps prevent deeper wrinkles from forming.


Because the effect is temporary, muscle movement gradually returns. This is why treatments need to be repeated periodically to maintain results.


What does anti-wrinkle injection treatment involve


Treatment is quick, predictable, and generally very well tolerated. A series of small injections is placed into selected facial muscles using a very fine needle.


The sensation is usually described as quick pinches or stings. Ice or numbing cream may be used to minimize discomfort. The entire procedure typically takes only a few minutes.


There is virtually no downtime. Most patients return to their normal activities immediately after treatment.


What to expect at your first appointment


Your first appointment begins with a comprehensive consultation and facial assessment. Dr. Herrera evaluates how your muscles move, how your expressions form lines, and how your face rests when relaxed.


This assessment helps us understand your unique anatomy and develop a treatment plan based on balance, symmetry, and your desired outcome. Dosage and placement are carefully tailored so results can be as subtle or as noticeable as you prefer.



This personalized approach ensures that you still look like yourself, just more refreshed and at ease

When results appear and how long they last


Results from anti-wrinkle injections are not immediate. Most patients notice changes within two to three days as muscle relaxation begins to take effect.


Full results typically appear within 10 to 14 days. At this point, lines appear softer, and facial tension feels reduced, while the expression remains natural.


Initial treatments usually last three to five months. With consistent maintenance, some patients find results last longer over time as muscles become trained to relax.


What areas can anti-wrinkle injections treat?


Anti-wrinkle injections are commonly used in several areas of the face and neck.


Forehead and frown lines


These treatments soften horizontal forehead lines and the vertical lines between the brows. The goal is to reduce tension without creating a frozen appearance.


Crow’s feet and eye area


Injections around the eyes smooth fine lines while preserving the warmth and expressiveness of your smile.


Jawline, chin, and neck


Anti-wrinkle injections can reduce muscle bulk in the jaw for facial slimming, soften chin dimpling, smooth neck banding, and even help with teeth grinding or jaw tension. They are also used in non-cosmetic areas, such as excessive underarm sweating.


What is the difference between Botox and anti-wrinkle injections?


Botox is a brand name within the broader category of anti-wrinkle injections, also known as neuromodulators.

Other brands exist, and while they differ subtly, the most important factor in your results is the injector’s understanding of facial anatomy and muscle behavior.


At Herrera MD MedSpa, product selection is based on muscle strength, movement patterns, and desired subtlety. Technique always matters more than brand.


Are anti-wrinkle injections worth it?


For many patients, anti-wrinkle injections offer a powerful yet subtle way to refresh their appearance without surgery or downtime.


They soften existing lines, prevent deeper wrinkles from forming, and help the face look more rested. Patients often describe feeling more confident and aligned with their reflection.


Rather than looking different, you look like yourself on a good day.

What is the best injection or treatment for wrinkles


The best treatment depends on the type of wrinkle being addressed. Dynamic wrinkles respond best to anti-wrinkle injections.


Static wrinkles or deeper folds may require additional treatments such as dermal fillers or PRF. In many cases, combining treatments creates the most natural and balanced result.


At Herrera MD MedSpa, treatment plans are fully customized and may evolve over time based on your face and goals. Learn more through our injectables and PRP clinic.


Safety, risks, and side effects


Anti-wrinkle injections are considered very safe when performed by trained medical professionals.


Common side effects include temporary redness, swelling, tenderness, or mild bruising at injection sites. Rare side effects can include headache, flu-like symptoms, or temporary heaviness in treated areas. These effects always resolve.


Certain conditions, such as pregnancy, breastfeeding, or specific neuromuscular disorder,s are contraindications. A thorough medical history is always reviewed beforehand.


Physician-led injections significantly reduce risk and ensure appropriate dosing and placement.


How to care for your skin after treatment


After treatment, general guidance includes avoiding rubbing the area and not lying flat for several hours. This allows the product to settle correctly.


Staying hydrated, protecting your skin from the sun, maintaining a good skincare routine, and managing stress all help extend the longevity of your results.


Most patients maintain results with treatments every three to four months.


Choosing a trusted injector near you


When it comes to anti-wrinkle injections, technique matters more than price or convenience.


The right injector understands facial anatomy, proportion, and restraint. Over-treatment is far harder to correct than under-treatment.



At Herrera MD MedSpa, every treatment is performed or overseen by a physician. The goal is always a subtle enhancement that respects your natural features. Explore our injectables and PRP clinic to experience care rooted in precision and integrity.
