In which injections is hyaluronic acid commonly used?

Hyaluronic acid is a naturally occurring substance in the body that is commonly used in dermal fillers to provide volume and hydration to the skin. Restylane is a brand of dermal filler that specifically uses hyaluronic acid as its active ingredient. This makes it highly effective for treating facial wrinkles, lips, and providing overall skin rejuvenation by adding moisture and volume.

In contrast, while products like Botox are used for reducing muscle activity to smooth out wrinkles, they do not contain hyaluronic acid. Collagen injections, although once popular for filling wrinkles, utilize collagen protein, not hyaluronic acid, and have largely been replaced by hyaluronic acid fillers in aesthetic procedures. Vollure is another hyaluronic acid-based filler but is not the most widely recognized or established option compared to Restylane. Therefore, Restylane is the quintessential example of an injection that incorporates hyaluronic acid, making it the correct choice.
