Fillers for wrinkles and volume loss are remarkable for what they can accomplish. But all fillers aren’t okay for everyone.

Take note of these circumstances that might mean you aren’t a good candidate:

  • Severe allergies with a history of anaphylactic shock
  • An allergy to collagen (if you want to use a filler containing collagen)
  • An allergy to lidocaine (many fillers contain lidocaine)
  • A tendency to form excessive scarring or thick scarring
  • A bleeding disorder
  • An active inflammatory condition — such as cysts, pimples, rashes or hives — or an infection. In such cases you should postpone treatment until the condition is controlled.

The safety of dermal fillers is unknown when used in pregnant or breast-feeding women, in people younger than 18 or when used with Botox and other wrinkle treatments.

You should make it a habit to disclose all medical conditions and medications being taken before having filler or toxin injections.
