Collagen Booster Effects: Do you sometimes have skin that looks weak and your pores look large?

Recently, my skin feels less firm and lacks firmness compared to before, so I am looking into collagen boosters.

I don't have deep wrinkles, but when I look at my cheeks, my skin seems a bit saggy, and my pores seem more defined than before.

I've always had enlarged pores on my nose due to sebum, but now that my cheeks are starting to show this, it seems like it's not just a sebum issue.

Even if I consistently use moisturizing creams or firming products, the feeling of hydration is only temporary, and the overall skin texture doesn't change much.

Can I expect a collagen booster to be effective in this condition?

I am also wondering if I should understand collagen boosters as a treatment that gradually firms the skin rather than immediately adding volume.

I would also like to consult on how many collagen booster sessions I need to see realistic changes in my pores or skin texture.
