Which comes first, a collagen booster or a lifting procedure?

I am writing to inquire because I am having trouble deciding whether to look into a collagen booster or a lifting procedure first.

Lately, my jawline seems to have become a bit less defined, and the elasticity in my cheeks isn't what it used to be, so I was wondering if I should get a lift. However, my skin isn't sagging that much yet. People around me have suggested that it might be a good idea to try managing my skin itself first with something like a collagen booster.

But I don't really know the different types of procedures, so I'm not sure what criteria to use to choose one lol

Would it be correct to say that collagen boosters focus on improving skin elasticity and texture from within, while lifting focuses on refining facial contours? If I need both, I am also curious about the natural order in which I would receive them.

I don't want a drastic change; I just want my face to look less tired and my skin to look a little firmer.
