Some people may experience discomfort or pain. The local anesthetic in some of the fillers provides you with a more comfortable treatment experience. You can discuss with your doctor whether you will need additional pain relief.

Your doctor can advise you regarding whether a dermal filler treatment will benefit you. It's important to tell your doctor everything, including your medicines, allergies, and any other medical conditions you've had in the past. Your practitioner will discuss potential side effects from the injection of the filler and how serious they may be. You should tell your doctor if you've had previous aesthetic treatments, including surgical and non-surgical ones.

Patients with an allergy to the ingredients (including anaesthetic) of the filler should not receive treatment, as well as patients with bleeding disorders, or patients who have active skin disease or inflammation near the area to be treated. You can discuss contraindications, precautions, and warnings with your doctor before dermal filler treatments.

If you're pregnant, planning to become pregnant, or breastfeeding, it's best to not use any dermal filler products, because they haven't been adequately tested.

After the treatment, you should be given advice on post-treatment care. It is normal to experience some post-treatment pain, redness, swelling, pain, itching, and redness at the treatment site. See: What are the possible side effects?

Discuss potential treatment risks with your doctor. Sometimes there is a need for a touch-up treatment to achieve optimal results.

The effects of dermal fillers gradually diminish with time, because they are non-permanent injectable products. Treatments can last up to 18 months, but can be different depending on the treatment area, the product used and the characteristics of the individual. Additional treatments, or top-up treatments, can be undertaken to maintain the aesthetic result (see below).
