Fillers are injectable substances that are used to add volume to the face and reduce the appearance of wrinkles and fine lines. Fillers can also be used to correct facial asymmetry and to improve the overall appearance of the face.

There are two main types of fillers:

• Hyaluronic acid (HA) fillers: HA fillers are the most common type of filler. HA is a naturally occurring substance in the body that helps to keep the skin hydrated and plump. HA fillers are temporary and typically last for 6 to 12 months.
• Non-HA fillers: Non-HA fillers are less common than HA fillers, but they can last longer. Non-HA fillers include calcium hydroxylapatite, poly-L-lactic acid, and polymethylmethacrylate.

Fillers can be used to treat a variety of areas on the face, including:

• Cheeks
• Lips
• Tear troughs (under-eye hollows)
• Chin
• Jawline
• Nasolabial folds (smile lines)
• Marionette lines (lines from the corners of the mouth to the chin)

The duration of fillers depends on the type of filler used and the individual’s metabolism. HA fillers typically last for 6 to 12 months, while non-HA fillers can last for 1 to 5 years.

Fillers are generally considered to be safe and effective treatments. However, there are some potential side effects, such as bruising, swelling, and redness at the injection site. Other, less common side effects include infection, allergic reaction, and granuloma formation (bumps under the skin).

Fillers are not recommended for people who are pregnant or breastfeeding, or for people who have a history of allergic reactions to the ingredients used in fillers. Fillers are also not recommended for people with certain medical conditions, such as autoimmune diseases and bleeding disorders.

There are a number of alternatives to fillers, including other injectable treatments, such as Botox, and non-invasive treatments, such as laser skin resurfacing and chemical peels.

The best way to choose the right filler for you is to talk to your doctor. They can assess your individual needs and recommend the best type of filler for you.

It is also important to choose a qualified provider who is experienced in injecting fillers.
