Comparison
Where the products actually differ
The differences below are real but smaller than the marketing around them suggests. In practice, who injects you and how they place the product matters more than which of the four is in the syringe.
-
Onset
How soon it starts working
All of them begin to take effect within roughly three to five days, and all reach their full result somewhere around two weeks. Injectors commonly describe one product as having a slightly quicker onset than the others, though individual response varies more than the products do. If you are timing around an event, the two week rule applies regardless of which one is used.
-
Spread
How far it travels from the injection point
Some products diffuse a little further from where they are placed than others. Wider spread can be useful across a broad flat area such as the forehead, and unhelpful in a small precise area near the eye or brow where the aim is to affect one muscle and not its neighbor. This is the difference injectors care about most, and it is a reason a practice might carry two products rather than one.
-
Units
Why unit counts are not comparable
Units measure potency, and each product's units are defined against its own standard. A unit of one is not a unit of another, and the numbers are not interchangeable. One product in particular is dosed in substantially higher unit numbers for the same clinical effect, which makes its per unit price look far lower than it is. Always compare the total, not the rate.
-
Duration
How long the effect lasts
Three to four months is the common range across the category. One newer product is marketed on longer duration, and real world experience of it varies. Duration depends heavily on the area treated, how much was used and individual metabolism, and those factors swamp the differences between products for most people.
-
Price
What actually drives the number
Because unit counts differ between products, and because some practices price per area instead of per unit, the only comparison that means anything is the total cost of treating your specific areas with the specific product a practice intends to use. A lower rate per unit routinely produces a higher total.
Cost
What it costs in Napa
Most people in the Napa area pay roughly $12 to $20 per unit, or $300 to $700 for a typical session. Prices vary by provider and treatment area, so ask for a quote at consultation.
The per unit rate is the number practices advertise and the least useful one to compare across brands. Because units are defined differently by each manufacturer, a practice quoting a low rate may simply be using a product that requires more units to achieve the same result. The total for your treatment plan is the only figure that compares cleanly.
Manufacturer loyalty programs are a real factor in this category. Each of the major products has one, they discount meaningfully over a year of treatment, and they only pay out on their own product. If you expect to keep up treatment, which product a practice carries may affect your annual cost more than its per unit rate does.
Questions worth asking about price
- Which product would you use for my areas, and what is the total for that plan?
- How many units does that come to, and how does that compare to what I paid last time?
- Do you participate in that product's rewards program?
- If I want to try a different product next time, does the pricing change?
Suitability
Who it tends to suit
Choosing between these products is a conversation to have with an injector rather than a decision to arrive with. The honest position is that for most people, in most areas, any of the four will produce a comparable result in competent hands. The cases where the choice genuinely matters are narrower: a very broad forehead, a delicate area near the brow, or someone who has previously found one product wore off unusually quickly.
One situation does argue for a specific switch. A small number of people develop resistance to a product over repeated treatment and find it stops working as well. One product in the category is formulated without the accessory proteins thought to contribute to this, and providers sometimes suggest it in that situation. It is not a common scenario and it is a clinician's call, not a self-diagnosis.
Providers screen the same way for all four, since they are the same class of product. That commonly covers pregnancy and breastfeeding, certain neuromuscular conditions, known sensitivity to ingredients, and active infection at the injection site.
If a product has not worked well for you before
- Say which product it was and roughly when, if you know.
- Describe what happened: no effect at all, or an effect that faded unusually fast.
- Ask whether the dose or the placement might explain it before changing product.
- Underdosing is a more common explanation than resistance.
Questions
Questions people ask
Is one of these products better than the others?
Not in a general sense. They are all licensed for cosmetic use, they all work by the same mechanism, and in competent hands they produce comparable results. The meaningful variables are the injector's skill, the dose and the placement. A practice that tells you one product is simply superior is overstating a difference that is real but small.
Why does one product need so many more units?
Because units are a measure of potency defined separately by each manufacturer against its own reference standard. There is no shared scale. One product's units are substantially smaller in effect, so more of them are needed for the same result. This is the single most common source of confusion when people compare quotes.
Can I switch between products?
Yes, and plenty of people do. There is no need to finish anything or wait beyond the normal interval between treatments. Tell the new provider what you had last time and roughly how it went, because that history is more useful to them than the brand name on its own.
Does one last noticeably longer?
One product is marketed on longer duration and some people do report that. Across the category the usual range is three to four months, and the area treated, the dose used and your own metabolism all shift that more than the product choice does. Results are temporary whichever is used.
Which one does my Napa provider carry?
Most practices carry one or two rather than the full range, usually because of pricing agreements and the loyalty program they participate in. It is a fair question to ask when you call, particularly if you have had a good result from a specific product before.
