There are two main types of nasolabial filler. 1. A method of injecting into the shallow layer of the skin to add volume to only the desired area. 2. A method of injecting deep into the skin to add volume to just the cheekbones and the nasolabial area next to the nose. Do I have a triangle zone next to the nose? Because that part was missing, I wanted to selectively fill only that area, so I went to a hospital that used method 1. However, if you inject it into a thin layer instead, the bad thing is that your skin may turn red. So, I covered it up with a BB... Number 2 is because you can't selectively enhance the area you want, so in a way it just adds volume to the entire cheek... (you have to filter it well) But I think it's better not to get nasolabial filler in the first place. You look like a monkey, and the area next to your nose where your nasolabial folds appear turns black, and your face looks funny rather than ugly haha. Look for it carefully and do it... I should have just had nose surgery when I got nasolabial folds. ㅠㅠ When you get nose surgery, it pulls the skin next to your nose and creates tension in the skin. It seemed to disappear
