Dermal fillers are made with several ingredients. Some of these are naturally occurring, while others are synthetic substances that help your body increase smoothness and produce more elasticity. Hyaluronic acid Hyaluronic acid is naturally created by your body. It’s mostly found inside the soft connective tissues and fluids around your eyes, in cartilage, and joints. HA in injectable fillers is extracted and reformulated to help produce more of the substance naturally. Calcium Hydroxylapatite (CaHA) Calcium hydroxylapatite is a mineral compound that is naturally occurring in people’s bones. Calcium hydroxylapatite is synthetically reproduced and injected to reduce creases in the nasolabial folds and to lessen frown lines. It improves volume and fullness. Poly-L-lactic Acid Poly-l-lactic acid is one of the most common types of dermal fillers for the face because it encourages the body’s natural production of collagen. It’s a non-toxic stimulator made from biodegradable material. It’s best for the lower half of the face. Polymethylmethacrylate (PMMA) PMMA is longer lasting than the other dermal fillers; it’s considered semi-permanent. This option is best for medium to deep lines, furrows, and wrinkles. It’s also good for acne scars and as a lip filler. All of these ingredients are FDA-approved as facial injections; they should only be given as a medical procedure by a licensed provider as a treatment for lines, wrinkles, or scarring.
