Will collagen boosters be effective in improving thin skin thickness?

Should I say my skin lacks firmness? When I pinch it with my fingers, it feels floppy rather than firm. I think it's because my skin is so thin, but I want to make it thicker and firmer. Would a collagen booster be effective?

I was originally planning to get a laser lifting treatment, but since my skin is naturally very thin and I lack cheek volume, I think I should improve the fundamental aspects of my skin beforehand to minimize side effects like sunken cheeks. If a collagen booster would be helpful, I was thinking of getting the treatment first. What do you think?

Please let me know how long it takes to see results in skin thickness or elasticity from a collagen booster treatment, and if I receive a lifting laser treatment after the collagen booster, how much of a gap should I leave between them.
