The value of the service is ultimately up to you to decide if you are getting what you pay for. Certainly there should be absolute transparency about how many units you are being treated with and which of the cosmetic botulinum toxin agents you are being treated with (Dysport or BOTOX). There are three treatment trends that are quite misleading: Advertising a small fee by area, but not defining what an area is. In Los Angeles, there are offices that advertise $99 or $199 BOTOX by area but to do an actual standard forhead and brow treatment, this might represent 10 "areas". You can do the math. Another scam is sell BOTOX by the unit. However, it is impossible for the consumer to know how many units are in fact in the syringe. It does not take a rocket scientist to understand that saline is cheaper than BOTOX or Dysport. A vial of BOTOX costs about $550 for 100 units. So if you are being offered BOTOX for $6 per unit, there is a good chance that you are going to get less that a unit of BOTOX for your $6. FInally many offices, glide over precisely how much medication by unit you are getting and instead price by "syringe." Again it is impossible to know what is in that syringe.
Look for honest offices. They will tell you how much product you are getting. Treatments will be every consistent in their effects from treatment to treatment for years. However, expect pay more for experienced physician injectors. Provided you like the service, generally the premium these injectors charge is worth it. This is also about peace of mind. If you don't agree, I am sure you can find a store front that provides a cheaper service. Please do not stay with an office you are not happy with.
