My skin has absolutely no elasticity when I pinch it; is a moisturizing collagen injection a surefire fix? ㅠㅠ

Lately, every time I look in the mirror, I feel so depressed because I can see my skin elasticity dropping drastically and my pores stretching vertically in real time, just like in my photos ㅠㅠ. Even when I gently pinch my skin, it doesn't return to the firm texture it used to be; it feels incredibly dry and rough, causing my makeup to cake and look terrible haha. My inner dryness is also severe, so I feel like topical cosmetics have reached their limit. That is why I’m looking into skin boosters that deliver nutrients directly to the dermis! If dry, inelastic skin like mine gets a skin booster to replenish moisture and collagen, will it get that subtle inner glow and firm texture like a peeled egg? I'm scared of the pain since they inject my whole face, and my biggest worry is how long the embossed marks will last ㅠㅠ. Those of you who have tried skin boosters for elasticity management, please leave some vivid tips haha.
