My face has lost elasticity and is sagging; will the Livicol be extremely painful? ㅠㅠ

As I get older, my skin elasticity is dropping rapidly; I can see my cheeks sagging and my facial contours collapsing. On top of that, the dryness deep inside my skin is so severe that topical cosmetics alone simply aren't enough to fix it. I need to strengthen the skin barrier by directly injecting collagen into the deep dermis layer. Livicol I was highly recommended injection treatments, so I am seriously looking into them! Since they use a needle to inject densely all over the face, the feeling when getting them pain Is it painful enough to bring me to tears? ㅠㅠ I'm curious if even a scaredy-cat can endure it if I apply a generous amount of numbing cream for a long time, and how long the bruising or embossing marks last lol. I really want to make sure it replenishes collagen. Livicol To the seniors who have actually been hit, seriously Livicol Please give me some advice on whether it works really well lol
