How many Botox units, by area

Their generic names are onabotulinumtoxinA and abobotulinumtoxinA. Xeomin, Jeuveau and Daxxify are other brands of the same class.

Dysport starts working slightly sooner. In a split-face study comparing the two at a three to one ratio, both were working by day two and Dysport was measurably ahead at days four and six. The gap closes once both are fully in effect at two weeks.²

Dysport is widely said to spread further from the injection point. The trial that actually measured it found the opposite at equal labeled units, with Botox covering a larger area, and concluded that spread follows the strength of the dose rather than the brand. Dosed equivalently rather than unit for unit, the two behave much the same.³

On the conversion itself: Dysport's own labeling states that its units cannot be converted into any other product's. Clinicians convert anyway, because patients need to compare quotes, and two and a half to three to one is the ratio used in practice and in the comparative literature.¹

They are the same protein, botulinum toxin type A, sold by different companies under different names. Both block the signal from nerve to muscle, both wear off over three to four months, and both do the same job. The difference that matters is the unit scale: a Dysport unit is weaker, so the same result takes roughly two and a half to three times as many of them, which is why a Dysport quote is always a bigger number and why comparing the two without converting is meaningless. Dysport starts working slightly sooner, by a day or two, and that difference disappears once both are fully in effect at two weeks. The common claim that Dysport spreads further from the injection point is not supported by the trial that measured it, which found spread tracks the strength of the dose rather than the brand. Everything at Aahana is quoted in Botox-equivalent units, so the number you are given means the same thing either way.

Almost always a placement problem rather than a dose problem. The frontalis is the only muscle that lifts the forehead, and several muscles pull it down. Relax the lifter without accounting for what opposes it and the forehead sits lower than it did. Relax it unevenly across its width and the outer brow can peak into an arch that was not there before. Both are avoided the same way: assessing the face at rest and in movement before anything is injected, treating the forehead together with the muscles between the brows rather than on its own, and keeping a first session conservative with a review at two weeks, so the adjustment is adding rather than waiting out a result you did not want. Reading which forehead will tolerate what, and where a particular brow will sit afterwards, is judgment built on volume: Dr. Mundluru has injected thousands of patients across a wide range of face shapes and muscle patterns.

Frozen is a decision about amount and placement, not a property of the product. Complete stillness between the brows is usually what people are asking for there. The same approach carried across the whole forehead is what takes expression out of a face. How much movement you keep is worth saying out loud at the consultation, because wanting a smooth forehead and wanting to still raise your eyebrows are different goals that need different amounts.

No. Muscle activity returns to where it was and so do the lines. What usually sits behind that impression is seeing your own face move again after months of not seeing it move, which makes familiar lines read as new. Over years of repeated treatment, lines at rest tend to be softer rather than deeper, because the muscle has spent less of that time creasing the skin.

The product behaves the same way in everyone. Botulinum toxin acts on the signal between nerve and muscle, and that signal does not vary by skin tone, so there is no question of it working less well or carrying more risk. Skin tone matters a great deal for treatments that work through heat or controlled injury, where pigment can respond to the inflammation, and a neuromodulator is not in that category. A history of keloid or hypertrophic scarring is worth raising, though that is about how a needle puncture heals rather than about how the product works. What does differ is anatomy, and what people are asking for. Muscle bulk, where a muscle sits, the height of the forehead, the shape and set of the brow, the fullness of the lower face: all of it varies between people, and it varies with ancestry as much as with anything else. So does the goal. What reads as a natural brow, how much jaw width someone wants to keep, how much movement they want left in their face, is not the same conversation with every patient, and an amount taken from a template rather than from the person in front of you is how a result ends up technically correct and wrong for them. Dr. Mundluru has injected thousands of patients across a wide range of faces, and published dermatology research on skin of color during his training. The anatomy and the goal are the variables here, not the product.

It depends what happened, and the first useful thing to know is that none of it is permanent: it wears off in three to four months. In the meantime an asymmetry can sometimes be balanced by treating the muscle working against it, though adding product to a result you already dislike is a judgment call rather than an automatic fix. Bring photographs from before and after if you have them, and the record of what was used and how much. Knowing the product and the amount is most of the diagnosis.

Usually 10 to 20, and not on its own. The frontalis is the only muscle that lifts the forehead, so relaxing it while the muscles that pull it down keep working is what leaves a forehead sitting heavy. The glabella is treated at the same time, which adds its own amount on top.

In some areas, yes. Brow lift and the upper lip are genuinely small-amount areas. In the glabella and the masseter, too little produces a partial result that wears off early and reads as the treatment not working, which costs more than treating it properly once.

Only where the first amount was too small for the muscle. Once a muscle has what it needs, more units do not extend duration. They add cost and raise the chance of an unnatural result.

Everything at Aahana is quoted in Botox-equivalent units, so a number you are given here means the same thing whichever product ends up being used. Comparing against somewhere else means converting first: two and a half to three Dysport units do the work of one Botox unit, so divide a Dysport unit count by about three before setting it beside a Botox one. Separately, an area price and a unit price are not the same thing. An area price assumes an amount and a unit price does not, so neither tells you what you are actually getting until you know both the number and the product.
