Regarding Celle Diem, does it really make the skin firm and supple?

Perhaps because my skin is losing elasticity as I get older, I am worried because the unevenness and enlarged pores in my butterfly zone are particularly noticeable whenever I look in the mirror after washing my face.

No matter how good the moisturizer I applied, only the surface of my skin remained oily while the inner dryness wasn't resolved at all, so I eventually turned my attention to dermatological procedures. Besides the popular injections that many people already get, I've noticed quite a few reviews for Celle Diem lately, so I became interested and am looking into it. Is it a new product?

Since my skin is so dry and rough, if I am going to spend the money on regular care, I want to definitely feel a noticeable change in its texture becoming smoother. However, I am worried that the pain from the Celle Diem injection procedure might be too severe, causing me to give up halfway, or that marks like unevenness or bruising might linger for a long time afterward, interfering with my daily life.

Does Celle Diem really feel like it plumps up your skin from deep within, justifying the price?
