The price of botulinum toxin (commonly referred to as Botox) per unit can vary significantly based on several factors including the country, the clinic, brand, and the specific formulation used. As of my last update, here are some general considerations:

1. Situación geográfica: Prices can vary widely from one country to another and even within different regions of the same country.
2. Clinic and Practitioner: Prices may differ depending on the reputation and experience of the clinic and the practitioner.
3. Brand and Formulation: There are different brands of botulinum toxin (e.g., Botox, Dysport, Xeomin), and each may have different pricing.
4. Quantity Purchased: Sometimes, buying in larger quantities can reduce the per-unit cost.
5. Purpose of Use: Cosmetic treatments might be priced differently from therapeutic uses.

Here are some estimated ranges for Botox prices per unit in various settings (prices are approximate and can vary):

• United States: $10 to $20 per unit.
• Europe: €8 to €15 per unit.
• Asia: $6 to $15 per unit.

Keep in mind these prices are just general estimates and can vary. For the most accurate and current pricing, it’s best to contact local medical aesthetic clinics or suppliers directly.
