I have treated thousands of faces with botulinum toxin type A, and the same questions keep coming up during consultations: How many units do I need? Why does my partner need more than I do? Can we do a lighter dose so I still move? The right answers are nuanced. Dosage depends on muscle strength, anatomy, the product used, and the effect you want to see. Gender plays a role, but not in a one‑size‑fits‑all way. This guide distills how experienced injectors approach dosing by area, what the numbers mean, and how to use them to build a plan that looks natural, lasts well, and avoids avoidable side effects.
Throughout, I’ll use “Botox” generically for onabotulinumtoxinA, the most recognized brand. Other neuromodulators exist, and I will note conversions and caveats where useful. If you are searching for Botox near me or researching Botox treatment reviews for 2025, the dosage principles here will help you vet advice, compare clinics, and ask focused questions during your consultation.
How dosing works, and why “units” are not universal
A unit is a measure of biological activity specific to each manufacturer’s testing method. Units of Botox are not interchangeable with units of Dysport, Xeomin, Jeuveau, or Daxxify. Most providers use a rough conversion when switching products, for example Dysport often requires more nominal units to achieve a similar effect, but your injector should rely on experience with each product, not math alone.
For onabotulinumtoxinA, the U.S. FDA has on‑label dosing ranges for common cosmetic areas. Real‑world practice extends beyond labels to off‑label areas like masseter reduction, lip flip, chin dimpling, gummy smile, nasal “bunny lines,” and necklace lines. Every area has baseline unit ranges. Within those ranges, we adjust based on:
- Muscle bulk and baseline movement. Skin thickness and elasticity. Face shape and facial animation patterns. Gender, age, and hormonal influences. Past response to neuromodulators and your Botox results timeline. Desired finish: crisp and still, or soft with maintained motion.
Units per injection site and the number of injection points both matter. A total of 20 units spread across five points behaves differently than 20 units in two points. Distribution is a large part of technique.
Typical dosing by area, with real‑world adjustments
Numbers below reflect common starting points I use with Botox in healthy adults, assuming standard dilution. They are not prescriptions and should be tailored after an in‑person exam.
Glabella (frown lines, the “11s”): Most patients land between 12 and 25 units. The FDA‑approved on‑label dose is 20 units in five sites. Petite female patients with fine lines may look great with 12 to 16. Strong corrugators and procerus, common in men and in people who scowl while reading screens, often need 20 to 30. If your brows pull inward and down like a scissor action, underdosing here leads to partial relaxation and a frown that recovers quickly.
Forehead (horizontal lines): Typical range is 6 to 20 units spread across 5 to 10 points. The frontalis lifts your eyebrows, so over‑treating creates a heavy, flat look. I begin with 6 to 10 in women with long foreheads and light lines, then ladder up on follow‑ups if needed. Men, or anyone with tall foreheads and strong frontalis activity, may require 12 to 20, but placement must be conservative in the lower third to avoid brow droop. Pairing with appropriate glabellar dosing helps maintain a balanced brow position.
Crow’s feet (lateral canthal lines): Expect 6 to 12 units per side, typically in three injection points. I adjust for eye shape, smile width, and whether you rely on the orbicularis oculi for a genuine, full‑cheeked smile. Heavier dose softens the crinkles more, but over‑treating can make smiles feel less dynamic. In men with thicker skin or stronger orbicularis, 10 to 14 per side is common.
Bunny lines (nasal sidewall): Usually 4 to 8 units split on each side of the nose. This area responds quickly, and a little too much can subtly alter smile dynamics, so I favor conservative dosing with a 2‑week touch‑up.
Brow lift (lateral tail lift): Small micro‑doses near the lateral orbicularis, often 2 to 4 units per side, can open the eyes without the “surprised” look. This should be planned with the forehead and glabella strategy, not added randomly.
Lip flip: 4 to 8 units total into the upper orbicularis oris. Good for a subtle roll of the lip border and to reduce upper lip lines. It can make sipping from straws or pronouncing certain sounds feel strange for a week or two, so I prefer 4 to 6 for first‑timers. For fuller lips without toxin trade‑offs, combine with a tiny amount of filler rather than pushing the botox dose.
DAO (downturned corners) and gummy smile: 2 to 4 units per side for the depressor anguli oris helps lift corner descent. For gummy smile, 2 to 4 units at the levator labii superioris alaeque nasi on each side softens upper lip elevation. Anatomy varies and misplaced toxin can distort a smile, so precise injection technique matters more than the unit number here.
Chin (orange peel dimpling) and mental crease: 6 to 10 units total placed superficially in the mentalis. In older patients where chin overactivity contributes to marionette folds, treating the mentalis improves lower face smoothness and helps filler in the area last longer.
Masseter (jaw slimming, clenching): Big range, typically 20 to 40 units per side for cosmetic slimming with Botox, spread across multiple deep points. Heavier functional bruxism sometimes needs 40 to 60 per side. Men with square jaws or thick masseters often require higher starting doses. Results for slimming are gradual, with visible change at 6 to 8 weeks and better definition with repeated sessions. Chewing fatigue is possible in the first 1 to 2 weeks, which usually eases as you adjust.
Platysmal bands and Nefertiti neck lift: 30 to 60 units total across visible bands and the jawline, sometimes more in strong platysmas. A test session with fewer units can predict voice changes or swallowing sensitivity risks. For neck bands, combining skincare and energy devices provides better longevity than toxin alone.
Under‑eye crepiness: Off‑label micro‑doses, commonly 2 to 6 units per side, can improve fine lines but risk smile weakness and under‑eye puffiness if the injector goes too low or deep. I reserve this for select patients after crow’s feet are well balanced.
Each of these areas has injection sites that matter as much as the units. For example, crow’s feet injections placed too close to the lateral canthus can increase the risk of a temporary eyelid droop. Forehead injections too low can weigh on brow elevators. Precision is why qualified providers spend as much time charting injection points as counting units.
Gender differences: patterns, not rules
The hormone‑driven pattern you see in clinic is straightforward: male faces often need more units to achieve a similar effect. Testosterone and greater muscle mass mean stronger frontalis, corrugators, and masseters on average. Brow architecture differs too. Many men prefer movement and a flat brow line, not a high arch, so we dose the lateral frontalis and orbicularis carefully to avoid a feminizing lift.
As a starting observation, men frequently need about 20 to 30 percent more units than women in the upper face. Examples from my practice:
- Glabella: 20 to 30 in men versus 12 to 20 in women. Forehead: 12 to 20 in men versus 6 to 14 in women. Crow’s feet: 10 to 14 per side in men versus 6 to 12 in women. Masseter: 30 to 60 per side in men versus 20 to 40 per side in women for slimming.
Still, I have petite men who need fewer units and women with powerful corrugators who need more. Age, ethnicity, athletic training, and facial habits override gender stereotypes. The most reliable predictor of dose is how your face actually moves when you frown, lift, smile, and chew.
Light, standard, and full corrections: finding the right intensity
I describe three finish levels so patients can choose their aesthetic:
Soft motion: A light touch that reduces lines but keeps expressive movement. For the glabella, this might be 10 to 14 units. For the forehead, 6 to 10. Crow’s feet, 6 per side. This option suits first‑timers, screen workers who need their brows for expression, and performers who want range.
Natural stillness: The classic, polished look with minimal lines at rest and reduced movement. Glabella 20, forehead 10 to 14, crow’s feet 8 to 12 per side. This is the most common daily practice outcome.
Crisp correction: Max suppression for deep lines and strong muscles. Glabella 24 to 30, forehead 14 to 20, crow’s feet 12 to 14 per side. Best for deep static lines or when you accept a defined, controlled look.
These categories are guidelines. During follow‑up, we can add 2 to 8 units in specific points to fine‑tune outcomes. A two‑visit plan often delivers more natural results than front‑loading everything on day one.
Duration, maintenance, and the “banking” effect
Neuromodulators begin to take effect in 3 to 5 days, reach peak at around 10 to 14 days, and slowly wane over 3 to 4 months in the upper face. Some patients get 5 to 6 months, especially with repeat treatments and at higher doses. The masseter and platysma can hold relaxation longer due to muscle size and injection depth, but most people schedule maintenance every 12 to 16 weeks for consistent Botox results.
There is a real banking effect. If you keep muscles relaxed over time, you form fewer creases during daily animation, and skin lines remodel. Repeat sessions sometimes require fewer units for the same outcome once the muscle deconditions, although that is not guaranteed. On the flip side, very athletic patients with high metabolism, those who chew gum frequently, or heavy clenchers can burn through results sooner.
Safety, side effects, and how to minimize risk
Botox injections are considered safe when performed by a licensed, trained provider using sterile technique and FDA‑approved products. Common short‑term effects include pinpoint swelling, redness, a small bruise, or a mild headache. These clear within days. Less common but important risks are brow or eyelid ptosis, asymmetric smiles, heavy brows, smile weakness, or chewing fatigue. These are usually temporary and reflect dose or placement challenges.

Two technique points matter greatly. First, dilution and depth: different areas require different depths and spreads. For example, the mentalis needs superficial, precise placement to avoid chin heaviness. Second, anatomy awareness: moving half a centimeter can be the difference between a seamless brow lift and an unwanted eyelid droop.
Aftercare helps. Avoid heavy workouts, saunas, and upside‑down yoga for the rest of the day. Do not rub or massage injection sites. Keep your head upright for 3 to 4 hours. Makeup is fine after a couple of hours if the skin is intact and clean. Arnica gel can help bruises fade faster. For discomfort, a cool compress works well.
Cost, pricing models, and value beyond the per‑unit number
Botox cost varies by market and provider expertise. In the United States, onabotulinumtoxinA commonly ranges from 10 to 20 dollars per unit. Practices may charge per unit or by area. Per‑unit pricing feels transparent, but per‑area pricing can incentivize touch‑ups without nickel‑and‑diming. A glabella‑forehead‑crow’s feet package might run 450 to 900 dollars depending on dose and geography. Masseter treatment is usually 500 to 900 dollars per session given the higher units.
Deals and specials appear frequently, especially at medical spas and during manufacturer promotions. A lower headline price is not always cheaper if the clinic uses heavy dilution or underdoses to get you in the door. The best value comes from an injector who sets realistic expectations, documents your units and points, and delivers consistent results with fewer revisits. If you need Botox appointment booking online, look for clinics that publish their provider bios, explain their Botox injection technique, and show unfiltered Botox before and after pictures with lighting and angles that match.
Insurance coverage rarely applies to cosmetic sessions. Medically indicated uses, such as Botox for migraines or certain muscle spasticity conditions, can be covered in part. Your aesthetic treatments remain out‑of‑pocket.
What to expect before, during, and after the visit
A good consultation includes a medical history review, prior neuromodulator use, allergies, bleeding risks, and your aesthetic goals. Photos at rest and in motion help plan injection sites. We mark while you animate. Numbing cream is rarely needed. The injections feel like small pinches, often 5 to 15 minutes total for the upper face. If you are nervous about pain, bring an ice pack or ask for a vibration device as distraction.
Immediate changes are minimal. You might see tiny blebs that fade within 15 minutes. By day 3 you should feel subtle heaviness in treated muscles. At day 7 movement is reduced, and by day 14 the effect is set. If something feels uneven, request a follow‑up at two weeks. Early touch‑ups are best done with micro‑increments rather than aggressive additions.
Comparing products: Botox vs Dysport, Xeomin, Jeuveau, and Daxxify
Most patients can achieve similar results with the major brands when dosed and placed properly. Differences you might notice:
- Onset: Some report a slightly faster onset with Dysport. In my experience, the difference is a day at most and clinically minor. Spread: Dysport may diffuse a bit more, which can be an advantage in areas like the forehead and a liability near the lip. Technique compensates for this. Neutralizing antibodies: Xeomin lacks accessory proteins, which some believe may slightly reduce antibody formation risk. Actual clinical resistance to cosmetic doses is rare but possible with very frequent, high‑dose use. If a patient’s response declines over time, a product switch or dose adjustment may help. Duration: Daxxify is a newer option that may last longer in the upper face, potentially 5 to 6 months for many. Per‑session cost is higher, but it can reduce annual visit frequency. Botox duration remains reliable at roughly 3 to 4 months for most.
If you are deciding between botox vs fillers, remember that neuromodulators relax muscles to smooth dynamic lines, while fillers replace volume or support structure. For etched‑in lines at rest, a combined strategy often works better than trying to solve everything with more toxin.
Tailoring dose to skin, age, and lifestyle
Fine, thin skin shows lines sooner and may require a lighter touch to avoid surface rippling. Thick, sebaceous skin hides lines longer but needs more units when https://www.google.com/maps/d/u/0/edit?mid=1aUhYj2rCluFy9d7J1GP3L3n__OzIOE4&ll=34.976698163911216%2C-81.958175&z=11 they appear. Younger patients often choose smaller doses at longer intervals as part of preventive Botox for fine lines. Mature skin with established static lines benefits from full correction at first, then maintenance, sometimes with adjuncts like microneedling, laser, or retinoids for collagen support.
Endurance athletes metabolize neuromodulators more quickly anecdotally. People with high‑stress jobs or jaw tension may need more frequent masseter sessions at first. If you are on a maintenance schedule for Botox facial rejuvenation, consistency matters more than chasing every fine line. Plan sessions around important events, allowing 2 weeks for peak results and tweaks.
Avoiding a frozen look: it is about balance, not just smaller numbers
Patients often ask for the smallest number of units to stay natural. The goal is not minimal units. It is correct placement and proportionate dosing among muscle groups. If you only treat the forehead lightly while ignoring strong frown lines, your frontalis still fights downward pull and you end up with etched lines and tired brows. Treating the glabella properly allows you to use fewer units in the forehead while keeping an open, relaxed look. Balance creates natural results with fewer side effects. Imbalance creates heaviness, arches that look surprised, or smiles that feel off.
The role of touch‑ups and why two visits can outperform one big session
Experienced injectors favor a conservative first pass followed by a refinement visit 10 to 14 days later, especially for new patients. Small additions of 2 to 4 units in targeted points evenly finish the result. Over time, as we learn your response, we can do single‑visit treatments with confidence. If a clinic refuses to schedule adjustments or charges a full new visit for two units, factor that into your overall botox pricing comparison.
How many units do I need? Putting it together by scenario
First‑timer, female, fine lines: Glabella 12 to 16, forehead 6 to 10, crow’s feet 6 per side. Plan a two‑week check, likely adding 2 to 4 units where motion persists.
Male professional, moderate lines, wants movement: Glabella 20 to 22, forehead 10 to 14, crow’s feet 8 to 10 per side. Emphasize strategic forehead spacing to prevent heaviness.
Masseter slimming, female, mild clenching: 20 to 30 units per side, reassess at 8 weeks, repeat at 12 to 16 weeks for contouring.
Neck bands, early laxity: 30 to 40 units across bands and mandibular border. Combine with skincare and possibly energy treatments for neck tightening for best longevity.
Upper lip lines in a meticulous speaker: Start with 4 units lip flip and reevaluate. If articulation matters greatly, consider fractional laser and a micro‑aliquot of filler instead of pushing toxin dose.
These are starting points, not recipes. Your injector’s eye should trump any chart.
Myths, realities, and long‑term considerations
Botox builds up in your system. Not in the way most people think. The effect is temporary. Muscles atrophy slightly if kept still, making future treatments easier. True toxin accumulation is not a concern at cosmetic doses spaced appropriately.
Higher dilution is safer. Dilution changes spread and injectability, not intrinsic safety. Safety comes from correct anatomy, sterile technique, and appropriate total units.
More is always better for deep wrinkles. Overdosing can flatten expression and cause compensatory lines elsewhere. Deep static lines often require a combination of toxin, resurfacing, and possibly a touch of filler in etched creases after movement is controlled.
Botox is painful and requires downtime. In most cases, discomfort is brief and minimal. You can return to work the same day. Bruises happen but are rare with planning and good technique.
Botox alternatives can replace all uses. Skincare, peels, lasers, microneedling, and energy devices improve skin quality, not muscle motion. Fillers address volume. For dynamic lines and muscle‑driven issues like frown lines or clenching, neuromodulators remain uniquely effective.
Choosing a provider: what to look for beyond glossy photos
If you are searching for botox clinics or botox injections near me, prioritize experience over decor. Ask who will inject you and how many neuromodulator sessions they perform weekly. Look for a thorough consultation, clear documentation of units and points, and realistic botox treatment expectations. Good clinics welcome questions about botox risks, botox aftercare, and what happens if you need a tweak. Reviews help, but pay attention to consistent outcomes across different face types, not just the most dramatic before after images.
Two red flags: a clinic that cannot tell you the brand and dilution they are using, and one that offers botox home remedies or at‑home injections. These treatments belong in a clinical setting with medical oversight.
Building your treatment plan and schedule
A sustainable botox maintenance schedule balances aesthetics, budget, and lifestyle. Many patients rotate on a 3 to 4 month cadence for upper face, with masseter and neck as add‑ons every second or third visit. If you want to stretch the interval, accept lighter motion toward the end rather than chasing a rigid frozen finish. Document your units and response each time. Over a year, you and your injector should see patterns that inform smarter dosing, sometimes reducing the total or spreading points better for a natural look.
For event planning, book your botox appointment online 3 to 4 weeks before the date. This allows the full effect and a possible touch‑up. Avoid trying a new area right before a big event. Familiarity breeds predictable outcomes.
Final thoughts from the chair
The right dose is the smallest amount that achieves your goal when placed correctly, distributed intelligently, and balanced across opposing muscles. Gender guides the starting range, but your own anatomy and expression patterns drive the final numbers. If you remember three things, carry these into your next visit: communicate the finish you want, let your injector treat the whole animation pattern rather than chasing a single line, and schedule a short follow‑up for micro‑adjustments. That is how you trade guesswork for reliable, natural botox results, session after session.
