The cost of antiaging injections varies widely depending on the type and location. Botox typically costs between 10 to 20 dollars per unit, with most treatments requiring 20-60 units, totaling 200 to 800 dollars per session. Results last 3-4 months. Dermal fillers cost 500 to 1,500 dollars per syringe, with some people needing multiple syringes. Filler results last 6-18 months depending on the type and location. Costs also vary by geographic area, provider experience, and product brand. These are not one-time expenses, as maintenance treatments are needed to maintain results. Consult with qualified providers for accurate pricing in your area.
