Thank your for your question. It is common for patients to wonder how much correction/ enhancement 1 syringe of filler (Juvederm, Restylane, etc) can achieve. Most syringes are 1ml in size (this means they contain 1/5 of 1 teaspoon - it takes 5 syringes to fill 1 teaspoon). Trying to treat too many areas with one syringe will not give you the result you desire. Additionally, results will depend on: depth of wrinkles, amount of volume loss and which filler is chosen to use for treatment. Your best option is to consult an experienced, board certified plastic surgeon who will fully assess your face and take into consideration what you want to achieve. In our office, we create an individualized plan for each patient which details your concerns and gives you options as well as a guide for accomplishing a beautiful, natural result.
