Collagen Booster: How to Reduce Pain

Hello!! Lately, I’ve noticed my face sagging and losing elasticity, so it’s been stressing me out every time I look in the mirror. Cosmetics just aren't working, so I looked into treatments. I heard that collagen boosters naturally add volume and are good for improving skin texture, so I am leaving this inquiry.

I'm really looking forward to this because the collagen booster works by replenishing collagen from deep within the skin, so I think it will be perfect for my dull and sagging skin. However, since I tend to be a total wimp, my biggest concern is how painful the procedure will be. I've seen reviews where people often say it hurts even with numbing cream, so I'm a bit scared... Is there any way to reduce the pain of the collagen booster so I can get the treatment comfortably?
