I'm curious about the types of fillers

Recently, as I've been exposed to various information related to beauty, my interest in fillers has grown. I've always thought of fillers as a procedure used to add volume to the face or improve wrinkles, but hearing about the variety of fillers has made me even more curious.

First, I'd like to know about the basic types of fillers. I've heard there are several types, including hyaluronic acid fillers, calcium hydroxyapatite, and poly-L-lactic acid. I'm curious about the characteristics, pros, and cons of each. For example, hyaluronic acid fillers have the advantage of being natural and safe, but they have the disadvantage of being short-lived. On the other hand, calcium hydroxyapatite fillers are said to last longer, but I've also heard that they may have a higher risk of side effects.

Also, I think the types of fillers will vary depending on their intended use. I'd like to know the differences between fillers for volume and those for wrinkle improvement, and which fillers are appropriate for specific areas. For example, I'd like to know the differences between lip fillers and cheek fillers, and how each works.
